In a DC UPS ( Un-interruptible Power Supply ) , the charger simultaneously powers the DC load

as well as the battery. As long as the AC power to the charger is available and the charger is

working normally, the charger will supply the DC load as well as charge / oat the battery. In

case the AC power fails or if the charger stops working, the battery will automatically power

the DC load. As soon as the AC power to the charger is restored, the DC load will once again

be fed by the charger and at the same time the battery will be recharged.

CAUTION! Please ensure that the sum of the current drawn by the DC load and the current

desired for charging the battery is less than the maximum current capacity of the charger. To

use as a DC UPS, rst switch off the DC load and connect it to the battery. Now connect the

battery. Switch on the charger and then switch on the DC load.

Installation

MOUNTING

Mount the unit in a DRY location. Allow at least 4 inches of clearance around the heat sink

ns for adequate cooling.

POWER CONNECTION

The unit is supplied with power leads about 3 feet long. This should normally be adequate to

connect to a source of power. If you must extend the power leads, be sure to use at least a

good quality (typeTEW) AWG 8 gauge wire. The wire colours are:

Operation

Prior to turning on the unit, you must decide on which charging prole, 2 or 3 stage charging,

to use. To help you decide, please see the following section entitled 2 or 3 Stage Charging to

determine the charging prole.

Once you have decided on the charging prole you must set the switch to the correct

position. Set the switch to the correct position as shown on the label.

To turn the unit on, simply move the power switch to the ON position. The alarm buzzer will

sound and the Low Output LED will come on briey, and then the green OUTPUT ON LED will

illuminate.

When the unit is rst turned on, it will charge the batteries at a constant current and

the charging light will be on. After a period of time, which may be minutes to hours, the

batteries will reach the oat voltage at which time the charging light will go off, and the

charging current will reduce as necessary to maintain the batteries at that voltage. You

may check this voltage at the output terminals of the unit with a good digital voltmeter. As

shipped from the factory, the unit is preset to 13.6, 27.2, 36.3 or 54.4 VDC, which is generally

recommended for lead-acid batteries. If you wish to adjust the charging voltage, reach in

with a very small at blade screwdriver to rotate the potentiometer. Clockwise increases the

output voltage, and counter clockwise decreases it. It is advisable to check with the battery

manufacturer before changing the oat voltage.

110 VAC 220 VAC

Black/Brown - AC Hot Brown - AC Hot / Phase 1

White/Blue - AC Neutral Blue - AC Neutral / Phase 2

Green - Ground Green/Yellow - Ground

All connections should be made inside an appropriate junction box. The maximum current

draw from the 110 VAC supply is 16.2 amps, so a 20 amp circuit breaker should be used in the

circuit panel and for a 220 VAC supply, 8.1 amps is the maximum current draw, so a 10 amp

circuit breaker should be used in the circuit panel to feed power to the power supply.

This charger features user selectable 2 or 3 stage charging. The charging prole is selected by

turning the switch on the front panel to 3 stage or 2 stage charging.

A two-stage charger provides a constant current until the battery reaches its rated capacity

and then switches to a “oat” voltage. The current then reduces as necessary to maintain

the battery at the oat voltage. The charger can be connected to the battery indenitely and

will provide the appropriate prole. A two-stage charger is recommended in most instances

since it is the most versatile and can be permanently connected to attenuate the characteristic

discharge of unused batteries. A load can be put on the battery or batteries without altering its

ability to keep the battery at optimal charge.

A three-stage charger is the fastest charger. It charges the battery at a constant current until

the battery voltage reaches a slightly elevated level. The battery is maintained at this voltage

while the charging current diminishes to a low value, and then the battery is switched to the

oat voltage where it can be maintained indenitely. However, the charger cannot differentiate

between a current going to a load on the battery, or being absorbed by the battery, so it can

overcharge a battery supplying current to a load. A two-stage charger is preferred for “loaded”

batteries and a three-stage for idle or unloaded batteries during recharging.

All of Analytic Systems’ chargers include adjustable output voltage for charging standard or

deep cycle lead-acid, VLRA or gel type batteries.

Equalize Option

The purpose of the Equalize Option is to deliberately overcharge the battery at a low rate of

current to ensure that all cells are fully charged and to reduce the chance of sulfation of the

battery. During the Equalize cycle, the cells, which are fully charged, will produce Hydrogen

gas, and the cells, which are undercharged, will be brought up to full charge. An Equalize

cycle should be done once every 2-3 months, or whenever battery capacity appears to be

diminished. The Equalize Option also includes a battery temperature sensor to compensate the

charging voltage for battery temperature, as well as to shut the charger down if the battery

should become overheated. A second temperature sensor can be added to allow monitoring of

both batteries if the charger is connected to 2 banks of batteries.

An Equalize cycle can be initiated at any time by simply pressing the equalize start button

located at the front panel. This button is deliberately recessed to prevent accidental operation.

It is most easily pressed by using a ballpoint pen. If the charger is in the middle of charging

the battery (the Charging LED is on), the Equalize LED will ash. Once the main charging cycle

is complete, the Equalize cycle will begin and the Equalize LED will stay on all the time. If the

Charging LED is off when the button is pressed, the Equalize cycle will begin immediately.

The charger will charge the battery at approximately 10% of its normal rate (i.e. 5 amps for

a 50 amp charger) until the battery reaches equalize voltage and then the current reduces as

necessary to maintain the battery at that voltage. Three hours after the Equalize cycle begins,

the charger will return to the oat mode where the battery can be maintained indenitely. If

the battery temperature reaches 120 degrees F (50 degrees C) the equalize cycle will end and

the charger output reduced to a very low voltage until the battery cools, and then the charger

will return to the oat mode.

Remote Battery Temperature Sensor Installation

The remote battery temperature sensor allows the monitoring of the battery bank so that

the charging prole can be adjusted to optimally charge the battery bank depending on the

temperature of the battery bank. NOTE: The temperature sensor must be used during an

BATTERY TEMPERATURE SENSORS

Up to 2 battery temperature sensors can be connected to the charger to allow temperature

compensation of the battery charging voltage (1 is supplied with the unit). If only the 1 sensor

is used, it MUST be plugged into the ‘BATT 1’ connection on the front panel of the unit. If no

sensor is used, the charger will default to standard output voltage.

For installation instructions of the temperature sensor, please see the section entitled

Remote Battery Temperature Sensor Installation.

Troubleshooting

This unit provides LED indicators and a buzzer to help diagnose any problems. The unit should

sound the buzzer to alert you prior to shutting itself down. You should immediately check the

indicators to determine the cause of the shutdown.

CHARGING Indicates that the battery charger is charging the batteries:

If the LED is not on, the batteries may be fully charged and the charger is supplying a oat

voltage to the batteries to keep them fully charged.

LOW OUTPUT Indicates that the output voltage is below normal because:

The current demanded by the devices connected to the unit exceeds the maximum output

current rating, causing the output voltage to drop to maintain the current at the maximum level,

The input voltage is not high enough for unit to operate,

LOW INPUT Indicates that the input voltage is below normal because:

The input voltage is not in the correct range for proper operation of the unit.

OVERTEMP Indicates that the Battery Charger is running too hot because:

Too much power is being drawn, turn off or unplug some devices.

The Battery Charger is located in a poorly ventilated area.

If the load exceeds the continuous rating for too long a period, the temperature sensor inside

the unit will turn off the outputs. After the unit cools sufciently, it will automatically come back

on. If this happens frequently, remount the unit for increased airow so it cools better.

equalize cycle or damage to the battery may occur.

The battery temperature sensor may be installed in many different ways, so long as the sensor

stays in contact with the battery. The preferred method is as follows:

The batteries to be charged will be placed on a platform made of wood. Prior to placing the

batteries on the wooden platform a cavity is hollowed out such that the sensor will t inside

the cavity and be ush with the battery. Place the sensor inside the cavity facing the proper

way (this is shown on the sensor). Next connect the sensor wiring to the telephone jack

marked “Batt 1” on the front panel of the unit. Note: If there is only one temperature sensor, it

gets plugged into “Batt 1”. If there is a second temperature sensor, it should be plugged into

to the phone jack labeled “Batt 2”.

If the load exceeds the continuous rating for too long a period, the temperature sensor inside

the unit will turn off the outputs. After the unit cools sufciently, it will automatically come

back on. If this happens frequently, remount the unit for increased airow so it cools better.

Dry Contact Relay

Dry contact output fail relay is available at the front panel. Pin1-2 is normaly close contact.

Pin2-3 is normally open contact.
