Conguration rules

¿

(1) The code of the module installed in Slot 1 is selected from Slot

1 output module specications.

(2) Slot 1 has to have a module selected.

(3) The code of the module installed in Slot 2 is selected from Slot

2, Slot 3 output module specifications and Slot 2 dedicated

output module.

(4) The code of the module installed in Slot 3 is selected from Slot

2, Slot 3 output module specications.

(5) It is possible to congure Slot 2, Slot 3 as an empty slot. (Refer

to Fig.1.1, Fig1.2)

If you do not install a module, code “O” (blank code) should be

selected.

However, It is not possible to congure both Slot 2 and 3 as “O”.

If you congure Slot 2 as “O” , pin no.5 to 7 of CN2 is NC.

If you congure Slot 3 as “O” , CN3 is not installed.

(6) Series operation is possible only if Slot 2 and Slot 3 are the

same module. Please refer to section 3.1

AC-DC Power Supplies Congurable Type

2 Function

2.1 Input voltage range

The range is from AC85V to AC264V. (please see SPECIFICA-

¡

TIONS for details).

In cases that conform with safety standard, input voltage range is

¡

AC100 - AC240V (50/60Hz).

If input value doesn’t fall within above range, the unit may not op-

¡

erate in accordance with specications and/or start hunting or fail.

If you need to apply a square waveform input voltage, which is

commonly used in UPS and inverters, please contact us.

When the input voltage changes suddenly, the output voltage ac-

¡

curacy might exceed the specication. please contact us.

2.2 Inrush current limiting

An inrush current limiting circuit is built-in.

¡

If you need to use a switch on the input side, please select one

¡

that can withstand an input inrush current.

Relay technique is used in the inrush current limiting circuit. When

¡

you turn the power ON/OFF repeatedly within a short period of

time, please have enough intervals so that the inrush current limit-

ing circuit becomes operative.

Surge current in the lter unit does not include (0.2ms or less).

¡

2.3 Overcurrent protection

An overcurrent protection circuit is built-in and activated at 105%

¡

of the rated current. A unit automatically recovers when a fault

condition is removed.

Please do not use a unit in short circuit and/or under an overcur-

rent condition.

Intermittent Operation Mode

¡

Intermittent operation for overcurrent protection is included in a

part of series. When the overcurrent protection circuit is activated

and the output voltage drops to a certain extent, the output be-

comes intermittent so that the average current will also decrease.

Output voltage shuts down when the output voltage continuously

¡

drops due to overcurrent protection.

Output voltage recovers from overcurrent protection by shutting

¡

down the input voltage and waiting more than 3 minutes then turn-

ing on AC input again.

2.4 Overvoltage protection

An overvoltage protection circuit is built-in. If the overvoltage pro-

¡

tection circuit is activated, shut down the input voltage, wait more

than 3 minutes and turn on the AC input again to recover the out-

put voltage.

Remarks :

Please avoid applying a voltage exceeding the rated voltage to an

output terminal. Doing so may cause a power supply to malfunc-

tion or fail. If you cannot avoid doing so, for example, if you need

to operate a motor, etc., please install an external diode on the

output terminal to protect the unit.

Instruction Manual

2.5 Output voltage adjustment range

To increase an output voltage, turn a built-in potentiometer clock-

¡

wise.

To decrease the output voltage, turn it counterclockwise.

2.6 Output ripple and ripple noise

Output ripple noise may be inuenced by measurement environ-

¡

ment, measuring method Fig.2.1 is recommended.

Remarks :

supply are crossed, ripple and ripple noise might not measure cor-

rectly.

Please note the measuring environment.

2.7 Isolation

For a receiving inspection, such as Hi-Pot test, gradually increase

¡

(decrease) the voltage for the start (shut down). Avoid using Hi-

Pot tester with the timer because it may generate voltage a few

times higher than the applied voltage, at ON/OFF of a timer.

When you test a unit for isolation between the input and output, or

¡

between output and terminal FG, short-circuit between all outputs

and function terminal.

When you test a unit for isolation between output V1,V2, and out-

¡

put V3,short-circuit between output V1 and output V2.

2.8 Start/stop sequence

The start / stop waveform changes due to external capacity, load

¡

current, etc, so please evaluate if start / stop sequence is required.

Please contact us if start / stop sequence is required.

3 Series Operation and

Parallel Operation

3.1 Series Operation

Series operation is possible only if Slot 2 and Slot 3 are the same

¡

module. Fig.3.1 shows an example of wiring.

Remarks :

Please be sure to have enough cooling in case one of the slots

stops due to activation of the protection circuitry.

In case of malfunction (Failure of protection circuit activation),

please stop the operation.

The combined output voltage of series operation is 48 V.

If the combined output voltage exceeds 60V, the safety agency

approvals are void.

4.1 Heat dissipation (derating)

For reliable and safe operation, please make sure the maximum

¡

component temperature rise given in table 4.1 is not exceeded.

Please refer to Fig.4.2 for derating information based on each

mounting methods.

Please allow enough ventilation for the power supply.

Temperature of points 1 through 5 should be lower than the up-

per limit temperature.

The expectancy life in the upper bound temperature (Points 1

through 5) is 3 years or more. Please refer to 4.5 if you want to

extend the longevity.

it with care.

If the output of an external power supply is within the range of 4.5
