DATASHEET / USER MANUAL
INSTALLATION
←The location must be dry, dust-free indoor use. The acceptable temperature range at full power is -25°C to +50°C. A higher
ambient temperature will limit the power, see diagram first page. The power supply is not waterproof. Keep it dry and away
from areas of high humidity to avoid the risk of electrical shock and damage to the charger.
↑The equipment may be installed either vertically or horizontally. If charger is installed vertical so that cable plate is
down,
then the floor and all below charger must be nonburning material. If material type below the charger is unknown, then
vertical assembling position is prohibited.
→To ensure sufficient ventilation, leave approximately 10cm free space to both ends of the unit.
The charging process generates explosive hydrogen gas. Keep the area well ventilated. Never use an open flame or equipment that
produces sparks near the charger. WALL MOUNTING
Screw the assembly board to the wall using the slots provided in the
back of the board
Then place the PSU to the assembly board and fasten it by using the
small screws on the sides on the board
DIN MOUNTING
Screw the din-clips to the assembly board
Then place the PSU to the assembly board and fasten it by using the
small screws on the sides on the board
Finally snap the PSU to the DIN-rail
Plug the main power cord into electrical socket. After switching on
the mains switch the unit is ready to be used.
POWER SUPPLY / CHARGING OPERATION
←Ensure that the unit is switched off and that the environment meets the conditions described previous section
↑Connect the output cables to the load / battery terminals: +cable to the +terminal and -cable to the -terminal.
NOTE ! Do not cut output calbes. If cables are cut, the output voltage is overcompensated as much as voltage drop in
cables was. This overcompensation may cause voltage variation depending on current consumption.
→Turn the power on by turning the switch to the I position.
↓During the normal power supply operation / charging process the STATUS light will show a constant orange light.
°To avoid sparking, turn the power off before disconnecting the cables.

DATASHEET / USER MANUAL
ANALOG CONTROL MODELS, type number example ADC4370/24AI
Analog control option allows full control for output current and voltages and it gives measured values for both of these.
There is also available +5V internal power source for logic use. The analog input have 500V electrical insulation to
power supply’s input and output.
PIN CONFIGURATION, MODULAR CONNECTOR
Interface to analog control card is made through AMP Modular 6
connector. It’s part number is 215-876-1. The product specification
number is 108-19064 and application number is 114-19019. Part number
for cable connector that fits to modular 6 is 737 336-1.
Controlling analog card:
All control voltages must be between 0 and 5 volts. Over 5V steering is not allowed. Logic for steering is positive so 5V
in target value means maximum value from power supply and 0V means minimum output. If controlling connector is
unplugged from modular connector, the power supply takes it’s minimum values for output.
Measured values can be read from measured signals. Measured voltages are scaled equal as target values. If power
supply lies on it’s voltage reference, then measured voltage should be equal as target. Same thing on current steering and
it’s measured value. Measured signals (both together) can be loaded only 20mA or proper operation is not guaranteed.
Modular connector is isolated from power supply’s input, enclosure and output terminals. That allows serial and parallel
connection to separate power supply’s so that equal steering voltages are used. Number or connected devices are not
limited. Only be sure that 500V insulation voltage is not exceeded. If connector in analog card is not a modular
connector (9 pin D-connector), it is a different version of analog controlled power supply and this manual is not valid to
it.
Connection example, using internal +5VDC power source and external potentiometers:
ADC4370 front panel
Location of tuning trimmers for analog control
Trimmers are covered by sticker
Pin configuration:
1. Ground
2. Target value for current
3. Target value for voltage
4. Measured value for current
5. Measured value for voltage
6. +5V, (max 20mA) output
+5V output can be used to feed logic
voltages for external circuits. Connection in
an example works as a potentiometer
controlled power supply. It is important to
notice that +5V output is not allowed to load
more then 20mA or proper operation is not
guaranteed.
Tuning instructions:
Attention !!!
Analog interface is tuned in a factory before it is delivered to customer. There should
not be any reason for tuning if card is used between 0-5V voltage values. Qualified
person is needed for tuning the device. Tuning can be done with a pair of digital multi
meters and example schematic above. Procedure is following:
1. Adjust from potentiometers 5V to voltage target and 2V for current target. Connect digital voltage meter to
power supply output. Tune from “Voltage Set” trimmer maximum output voltage to right value.
2. Connect digital voltage meter to Modular pin number 5. Tune from trimmer “Voltage Meas” so that digital
voltage meter shows always equal value as is in pin 3 (target voltage).
3. Connect digital current meter to output so that it short-circuits the output. Now tune current target
potentiometer to 5V. Tune from “Current Set” trimmer output current to value that is maximum value for
device according to it’s specification. Be sure that your current meter has a right range. Do never exceed the
current values that are specified for the device. If specified value is not known, take a contact to distributor.
4. Measure with digital multi meter voltage from Modular connector pin 4 Tune from trimmer ”Current Meas”
to equal with voltage in modular pin 2 (Target Current).

TEMPERATURE COMPENSATION MODELS, type number example ADC4370/24T
MASTER SLAVE CONNECTION
Using master power supply together with Slave unit.
Master unit can be trimmer adjustable standard model ADC4370/24 or analog controllable model ADC4370/24AI
(24V as an example).
Note !
Unit with relay alarm, type exampleADC4370/24H can’t be used as a master unit.
Slave unit is separate unit without any adjustment possibility, type ADC4370/24S or ADC4370/24SH slave with relay
alarm (24V as an example).
Note !
Slave with relay alarm, type ADC4370/24SH can’t control another slave unit.
If more current is needed adjustable Master power supply can be parallel or series connected via digital bus to Slave
power supply which equals Master but is without adjustment possibility. Then output current or voltage is doubled and
the both supplies can still be adjusted thought multi turn potentiometers. If still more current is needed then more Slave
power supplies can be connected in parallel so much that desired current value is reached. Supply’s output terminals and
communication bus terminals are isolated so that output's serial connection is allowed for more voltage.
Bus cable connection:
Master unit
Slave unit
Slave unit
Bus cables can be connected from
previous units to the next with the
same way. The first unit must be the
master unit (with adjusting knobs).
Wrong connection does not damage
the units but in that case slaves does
not follow the master's commands.
Quantities of the slave units are
unlimited.
Temp.comp. / sense
Modular connector
The temp.comp cable enables the charger to adjust the
output voltage in accordance with battery voltage and
temperature fluctuations

INSTRUCTION TO CHANGE THE PROGRAMMED VOLTAGE FOR TEMP.COMP./SENSE MODELS,
type number example ADC4370/24T
←Disconnect the power cord from the power line.
↑Disconnect the output cables from the battery to be charger.
→See the current code switch position of the unit.
↓See new switch position code from the programmed output voltages sticker on the unit
°Rotate the code switch under the sticker to the required position.
The hole of the code switch
The adjustment can be checked as follows:
Short-circuit the output cables of the charger (output short circuit).
Connect the charger to the power line.
Follow the Status-led color. Switch the charger on from the on/off switch.
Count all the number of green blinks.
There must be as much number of blinks as the code switch position number is.
Note!
If the position of the code switch is O, Status-led blinks only once and returns to red.
The code switch positions A…F respond numbers 10…15
☺Now the charger has been adjusted!
HINTS IF NOT SUCCEED
You didn't have chance to count the number of blinks
=> You can start the test with the on/off switch of the charger again and count.
You have made the wrong setting
=> Switch the charger off again and make the correct setting and count the blinking to check.
You cannot find the required charging algorithm on list available
=> Contact the seller / importer and ask if the charger can be up dated with the algorithm you need.

INSTRUCTION TO ADJUST TEMP.COMP/SENSE MODELS VOLTAGE BY THE TRIMMER,
type number example ADC4370/24T
If the battery is charged in a very cold place or desired constant voltage didn’t found from the charging algorithm list,
then there is a need to tune the output voltage. The output voltage can be tuned +/-5% from its nominal value.
←Choose such programmed output voltage, which can reach the desired voltage by +/-5% adjustment. Read the
instruction from ”Changing programmed voltage”.
↑Connect the voltage meter to output wires.
→Tune with a small screw driver the voltage calibration trimmer and check the result from volt meter. Clockwise
direction
increases the voltage. Look at the position below
Voltage trimmer
When desired voltage is found the tuning is ready.
NOTE !
The voltage tuning trimmer affects to every programmed voltage settings. The original list is not not valid without
returning the original tuning.
Incorrect trimmer tuning may be harmful to the battery.
