Features
Idling behavior
The CPS-i Series is permanently open-circuit proof. When an output
voltage is preset it comes stable. If a load is switched suddenly, the unit
stabilized within <1ms. An overshoot of the output voltage is irrelevant.
Start behavior
The power supply has a start delay of 1s to stabilize all measuring
circuits for the interface messages accurately. The power supply starts
with a ramp (soft start) of 100ms. The output voltage does not overshoot
- regardless of whether a load is connected or not.
Galvanic isolation and insulation
The switching power supply is galvanically isolated between the input
and the output. All major digital inputs and outputs of the interface are
electrically isolated.
V programming (Ureg)
The output voltage of the CPS-i power supply can be adjusted by a
control signal. The setting is linear to the input signal. The power supply
operates data stable even at very low output voltages.
C programming (Ireg)
The output current of the CPS-i power supply can be adjusted by a
control signal. The setting is linear to the input signal. The power supply
operates data stable even at very low output currents.
V Monitor (Umon)
The power supply provides real-time monitoring of the output voltage. It
is the exact and real value at the output terminals. If the sense line is
used, the real value is measured directly at the load. The latency signal
preset to the measured value is negligible, since the control circuit is
constructed completely analogously.
C Monitor (Imon)
The power supply provides real-time monitoring of the output current. It
is the exact and real value at the output terminals. If the sense line is
used, the real value is measured directly at the load. The latency signal
preset to the measured value is negligible, since the control circuit is
constructed completely analogously.
Constant Voltage or Constant Current Mode (CV/CC)
The device can optionally be operated as a DC voltage source or a
constant current source. The operating mode is signaled on the
interface.
Auxiliary Voltage (AUX)
The devices feature a 12V / 500mA auxiliary voltage to operate external
peripheral.
Potentiometer Internal Control (Uadj/Iadj)
If the power supply shall only set with the built in internal potentiometers,
the use of the internal auxiliary voltage is possible. The power supply
requires no external signals and can operate completely autonomously.
Potentiometer External Control (Uadj/Iadj)
If the power supply shall only set with external potentiometers, the use
of the internal auxiliaryy voltage is possible. The power supply requires
no external signals and can operate completely autonomously.
Sense Mode
The power supply has a sense mode to compensate for voltage drops of
2V per load line.
Fuse Mode
The unit can be operated in fuse mode. In the fuse mode, the unit is
turned off and locked when it was more than 5 seconds in constant
current mode to protect a connected defect load. The lock can be
controlled remotely or repeal by disconnection from the mains again.
Continuous Mode
The unit can be operated in continuous mode. In the continuous mode,
the power supply provides constant current mode in a continuous flow
and no ticker-operation.
Master-Slave Mode (Ureg-Out/Ireg-OUT)
The master-slave mode can be defined in the parallel operation. One device
can be set as the master, the other involved network units act as a slave and
the setting signals follow current / voltage, which are commanded by the
Master. This ensures that all devices are operated synchronously.
Current Share Bus (CS)
In parallel operation, the involved network components communicate with
each other and share the total power evenly to each other.
Remote Shutdown (SD)
All CPS-i devices have a remote shutdown (open collector or switching
contacts).
Inhibit Mode (Interlock)
The inhibit circuit reliably prevents unintentional starting of the power supply.
The control loop is internally locked. Since this blocking is done progressively
it is active even when the control signal, is missing due to a cable break or
temporarily suspends. A premature restart of the power supply is prevented.
The inhibit input can be connected to a relay or switch. If the contact is
interrupted, the power supply is switched off. If the contact is closed again, the
power supply restarts.
DC and AC Fail
By DC-fail the power supply reports that the power output is disabled.
By AC-fail the power supply reports an AC undervoltage. Both signals have
separate outputs. Each of them can be selected between NO and NC.
Over Voltage Protection (OVP)
On the interface is a message signal. Until the abolition of the fault the device
switches off.
Over Current Protecttion (OCP)
On the interface is a message signal. Until the abolition of the fault the device
switches off. (ticker mode)
Temperature Control (TEMP)
The operating temperature of the power supply can be monitored via a signal
applied to the interface output.
Temperature Alarm (TA)
If the device is in the critical range, a warning signal is applied to the interface.
Over Temperature Thermal Shutdown (OT)
The device has a thermal monitoring: shutdown with automatic restart. The OT
signal is applied to the interface.
Fan Failure Monitoring (FF)
If it comes to a fan failure or blocking, a signal is applied to the interface. The
speed signal of the fan is monitored. Thus, even a creeping fault is detected at
an early stage and there is a warning long sold separately in front of a fan
failure.
Fast Down Programming & PowerSink (PS)
For fast down programming an internal PowerSink is offered as an option. The
current sink discharges the output electrolytic capacitors and eleminates
skidding inge fed tensions.
A further output allows to control external PowerSink modules. The internal
current sink for quick programming must be installed at the factory.
Digitale Interface (in preparation)
The standard equipment of the power supply is an analog interface.
Optionally, the unit can be equipped on request with a digital interface.
Options include either a RS485 interface or a TCP/IP interface.
3D-HD (3D Heat Dissipation)
Our aligned and controlled heat dissipation design opens possibilities that are
formerly being reserved to custom design power supplies: Steplessly hard
mount of the CPS-i2000/3000 power supply modules in a 3D-room.
In practice that means that one can mount the modules into every angle
imaginable. Our 3D heat dissipation (3D-HD) ensures optimal cooling in each
mounting position you may consider.
