ULC-2 Overview
Metaphase Technologies’ Universal LED Controller (ULC-2) provides independent true
constant-current or voltage control of two LED loads from 0.02 to 4 Amps continuous
(DC) with a maximum output power of 60 Watts per channel. In Pulse (Strobe) Mode, the
ULC-2 is capable of output currents ranging from 0.1 to 40 Amps. Pulsewidths are adjust-
able down to 2 microseconds and external trigger rates up to 50kHz. In Voltage Mode,
ULC-2 output can range from 3V and 50V in 0.1 Volt increments.
The ULC-2 may be remotely controlled over Ethernet using Metaphase Technologies’ Me-
taBOSS Windows software or by third-party programs using the ULC-2’s Ethernet Com-
mands. Additionally, user-adjustments of the ULC-2 are provided by way of a user-friendly
LCD interface. Up to ve preset congurations may be saved and recalled to meet the
changing demands of today’s applications.

Wiring Connections
Please refer to the diagram below for LED output and trigger input connections.
The ULC-2 is powered by a user-supplied regulated power supply having the following ratings:
• 24VDC +/-10% recommended. Minimum of 9VDC with DC Mode output power derating
(see appendix E).
• 6Amp
• Switching topology (as opposed to linear)
• CE
ULC-2 LED Outputs
• Minimum recommended wire size - 18AWG
• Maximum recommended distance to LED - 10ft (for more info, see Appendix D)
• Un-powered, connect channel 1 & 2 LED loads to the positive and negative LED outputs.
Connecting or disconnecting LED loads while the ULC-2 is powered may damage the ULC-2
controller and/or the LED load.
• To minimize rise-time distortion and guarantee pulsewidth values, keep all LED load wires as
short as possible, and preferably twisted.
ULC-2 Trigger Inputs – (Minimum Recommended Wire Size – 24 AWG)
• For external trigger operation, each channel has its own separate trigger inputs.
Trigger pulses enable the LED output for a period set by the Pulsewidth parameter.
• Twist the + and - input wires together tightly (Twisted pair will pick up less noise)
• Make the trigger input wires as short as possible
• Route the trigger input wires separately from the LED output wires
• Cross wires for other circuits at 90° if necessary. Avoid running them parallel to each other.
(Reduce coupling of large transient noise sources to sensitive circuits)

Quick Start
Follow the steps below to quickly setup the Metaphase ULC-2 for basic operation using the
ULC-2 keypad:
1. With external loads disconnected, apply 24V power to the unit.
2. After applying power to the device, the boot-up screen will ash and display the current
software versions. At the bottom left you will nd the current Controller Version followed by the
two Driver Versions:
3. When prompted, choose Yes to enter the Setup Menus.
Though the intended operation of the ULC-2 may be only DC, Voltage or Strobe, the unit should be
congured to safely operate in all three modes in case the operation mode is set improperly at a later
time. Scroll through the various menus using the button located on the ULC-2 front panel.
*If setup prompt is missed at startup, the unit can be prompted to enter the setup menu at any time by
pressing the and buttons simultaneously.
• DC Current Limit – set the maximum DC current for which the LED load is rated. A setting of
200mA is the default. (Range 20 – 4000mA. This parameter applies only to DC Current Mode.)
• Strobe Current Limit – set the maximum peak current for which the LED load is rated for its
associated maximum pulse width. A setting of 1000mA is default. (100-40,000mA Range. This
parameter applies only to Strobe Mode.)

• Pulse width Limit – set the maximum pulse width associated with the maximum peak current.
A low value is safest, but may not
be seen if set too low.(2-60,000µs
range). A setting of 200µs is de
fault.
• Strobe Minimum Period Limit – set the minimum period for which external trigger
pulses will be allowed. A high
value, ex. 60,000 microseconds, is
safest. (20-60,000µs range). A set-
ting of 1000µs is default.
• Voltage Mode Enable – A setting of No-normal is default.
• Voltage Limit – Used to limit the maximum voltage output of the ULC-2. (3-50V range. This
parameter applies only to DC Volt-
age Mode). A setting of 3V is de-
fault.
• Trigger Source – Used to determine Internal or External trigger source. A setting of Internal is
default
• Trigger Polarity - Used to dene which edge of the trigger pulse the system res from.
Rising edge is the default, which is
typical for most users.
• Trigger Controls DC - Used to control DC LED output via trigger signal if set to YES; Default
(Normal) is a setting of NO. If “Trig Controls DC” is set to YES, then the trigger input will control
the DC Current or DC Voltage output. If “Trigger Polarity” is set to “RISING”, then the output
will be ON when a voltage is present at the trigger input. If “Trigger Polarity” is set to “FALLING”,
then the output will be ON when a
voltage is NOT present at the trig-
ger input.”

User-interface Menus
A. Setup Menus
The setup menus below appear only when the ULC-2 is powered on. Each menu described below ap-
plies to two channels independently. The menus include:
Trigger Source (Internal or External)
This menu allows the setting of the source of trigger when in Strobe mode. In normal operation, Exter-
nal trigger is selected, but for setup and testing purposes, users may elect to use internal trigger in an
effort to verify wiring connections and operation.
When set to External trigger, the ULC-2 will ignore external trigger input events received faster than
what is set by Strobe Minimum Period.
For Internal trigger, the frequency of the strobing output is set by Strobe Minimum Period. For both
types of trigger, the output Strobe Pulsewidth is determined by the Strobe Pulsewidth parameter.
Continuous (DC) Current Limit
This “Limit” menu provides the user a way to set the upper bound of the LED output DC Current up to
4 A current found in the “Run time” menus. For example, if the DC Current Limit is set to 1.6 Amps, the
DC current can be adjusted from 20mA to 1.6 Amps. Such a limit assures adjustments never exceed the
limits of the LED load. This limit applies only to DC Current Mode of operation. In DC Voltage Mode, the
ouput current may exceed 4A depending upon the load.
Voltage (DC) Limit
This “Limit” menu provides the user a way to set the upper bound of the LED output DC Voltage (found
in the Runtime menu) between 3 and 50 volts. For example, if the DC Voltage Limit is set to 24 volts,
the DC Voltage can be adjusted from 3 volts 24 volts. Such a limit assures adjustments never exceed the
limits of the LED load. This limit applies only to DC Voltage Mode of operation. In DC Current Mode, the
output voltage may exceed 60V depending upon the load.
Strobe (Pulse) Current Limit
This “Limit” menu provides the user a way to set the upper bound of the LED output Strobe current up
to 40 amps found in the “Run time” menus. For example, if the Strobe Current Limit is set to 9 Amps,
the Strobe current can be adjusted from 100mA to 9 Amps. Such a limit assures adjustments never ex-
ceed the limits of the LED load.
Strobe Pulsewidth Limit
This “Limit” menu provides the user a way to set the maximum LED output Strobe Pulsewidth found
in the “Run time” menus. For example, if the Strobe Pulsewidth Limit is set to 100 microseconds, the
Strobe Pulsewidth can be adjusted from 2 to 100 microseconds. Such a limit assures adjustments never
exceed the limit of the LED load.

User-interface Menus
Strobe Minimum Period Limit
This “Limit” menu provides the user a way to set the Minimum Period of the external strobe triggers
found in the “Runtime” menus. For example, if the Minimum Period Limit is set to 100 microseconds,
the Minimum Period can be adjusted from a maximum of 60 milliseconds down to a minimum of 100
microseconds. Such a limit assures adjustments never exceed the limits of the LED load.
Restore to Default
This allows for the device to be restored to original factory settings, but does not change the IP address.
First, reboot the device until the version menu is displayed.
When the above is displayed, hold the Down Arrow button to restore default settings.
The device should now be restored to the original settings and prompt you to enter setup mode.
Jump to Setup
Hold down the and buttons simultaneously to return to the Setup Menu at any time.
Resetting IP Address
In the unlikely event that, the software is corrupted, preventing IP address changes within the Setup
menu, the IP Address can be reset to 172.16.1.1 by pressing & simultaneously immediately after
power up. Alternatively, for applications where the controller does not have buttons on the front face,
the IP address can be reset to 172.16.1.1 by power cycling the controller four times, leaving it in pow-
ered on for 5 to 6 seconds each time. Exceeding the 6 seconds will reset the counter and subsequently
require four more power cycles.

Runtime Menus
These menus are shown after the setup menus. Each menu described below applies to two channels inde-
pendently. The menus include:
Mode - The Mode menu controls whether the ULC-2 output is continuous DC current, DC voltage, or
Strobed.
DC Current - The DC current menu controls the ULC- 2 out put from 20mA to the Current Limit value
set in the Setup menus. This menu ap-
pears only when the mode is set to DC
Current.
DC Voltage - The DC Voltage menu controls the ULC-2 output from 3V to the Voltage DC Limit value
set in the Setup menus. This menu appears only when the mode is set to DC Voltage.
Strobe Pulse Current - The Pulse current menu controls the ULC-2 output from .1 Amps to the
Pulse Current Limit value set in the Setup menus. This menu appears only when the mode is set to Strobe.
Strobe Pulsewidth - The Strobe Pulsewidth menu controls the ULC-2 output from 2 microseconds
to the Strobe Pulsewidth Limit value set in the Setup menus. This menu
appears only when the mode is set to Strobe.
Strobe Minimum Period - The Strobe Minimum Period menu controls the ULC-2 output from 60
msec down to the minimum value set by Strobe Minimum Period Limit
value set in the Setup menus. This menu appears only when the mode is
set to Strobe. The ULC-2 controller ignores trigger inputs faster than the
Strobe Minimum Period.

Runtime Menus
Strobe Trigger Delay
The Strobe Trigger Delay menu controls the delay between a trigger input and the ULC-2’s subsequent
pulse output from 60 msec down to the minimum. There exists a minimum delay of 6 usec (typical) by
default. This menu appears only when the mode is set to Strobe.
One-shot Internal Trigger
This menu allows the user to simulate one cycle of strobe output triggered by the internal trigger. Dur-
ing setup, this feature helps the user determine the appropriate values of pulse width, period, and strobe
current for their specic application. This menu appears only when the mode is set to Strobe.
Save/Recall (5 Presets)
This menu allows all Setup and Runtime settings to be stored in up to 5 presets. Each preset allows pa-
rameter settings for both Channels 1 & 2.
To use one of the presets, select what mode the device will be operating under (Strobe, DC Current, or
DC Voltage) and change settings as desired. After going through all settings, you will nd the Preset Display:
To save the options chosen select the preset number you would like with the button
After choosing which preset to use, select the down arrow to save.
