3.1 Isolation

■ For a receiving inspection, such as Hi-Pot test, gradually increase(decrease) the voltage

for a 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.

3.2 Mounting method

■ The unit can be mounted in any direction. When two or more power supplies are used side

by side, position them with proper intervals to allow enough air ventilation. The temperature

around each power supply should not exceed the temperature range shown in derating curve.■ Avoid placing the DC input line pattern layout underneath the unit, it will increase the line

conducted noise. Make sure to leave an ample distance between the line pattern layout and

the unit. Also avoid placing the DC output line pattern underneath the unit because it may

increase the output noise. Lay out the pattern away from the unit.■ Avoid placing the signal line pattern layout underneath the unit, this power supply might

become unstable.

Lay out the pattern away from the unit.■ Avoid placing pattern layout in hatched area in Fig.3.2.1 to insulate between pattern and

power supply.

3.3 Stress onto the pins

■ When too much stress is applied to the pins of the power supply, the internal connection

may be weakened.As shown in Fig.3.3.1, avoid applying stress of more than 19.6N

(2kgf) on the pins

horizontally and more than 39.2N (4kgf) vertically.

■ The pins are soldered on PWB internally, therefore, do not pull or bend them with

abnormal forces.

■ Fix the unit on PCB (using silicone rubber or fixing fittings) to reduce the stress onto the pins.

■ The base plate at Option"B" and "BC" is attached by glue.

When fixed to cabinet with screw, fix the power module before soldering the input and

output pins to prevent the power module being damaged.

Fig.3.3.1

Stress to the pins

3.4 Cleaning

■ When cleaning is necessary, clean under the following conditions.

Method : Varnishing, ultrasonic wave and vapor

Cleaning agents : IPA (Solvent type)

Total time : 2 minutes or less

■ Do not apply pressure to the lead and name plate with a brush or scratch it during the

cleaning.

■ After cleaning, dry them enough.

3.5 Soldering

(1) Flow Soldering :260℃ 15 seconds or less

(2) Soldering Iron :maximum 450℃ 5 seconds or less

(3) Reflow Soldering (option "-S")

■ Fig.3.5.1 shows conditions for the reflow soldering for option "-S" of CHS series.

Please make sure that the temperatures of pin terminals +VIN and -VOUT shown

in Fig.3.5.1 do not exceed the temperatures shown in Fig.3.5.2.

■ If time or temperature of the reflow soldering goes beyond the conditions, reliability

of internal components may be compromised.

Applications manual

For CHS series

● Notes to use option "-S"

■ Solder iron or other similar methods are not recommneded soldering method for

option "-S" because it may not be able to retain connectioin reliability between the PCB

and the Pins. Solder reflow is the acceptable mounting system for the option.■ Option "-S" is not reusable product after soldered on any application PCB.

3.6 Safety standard

■ To apply for safety standard approval using this power supply, the following conditions

must be met.● This unit must be used as a component of the end-use equipment.● The equipment must contain basic inslulation between input and output.

If double or reinforced insulation is required, it has to be provided by the end-use

equipment in accordance with the final build-in condition.● Safety approved fuse must be externally installed on input side.

3.7 Automatic Mounting (CHS series : option "-S")

■ To mount CHS series automatically, use the coil area near the center of the PCB as an

adsorption point. Please see the External View for details of the adsorption point.

If the bottom dead point of a suction nozzle is too low when mounting excessive force is

applied to the coil, it could cause damage. Please mount carefully.

3.8 Storage method (CHS series : option "-S")

■ To stock unpacked products in your inventory, it is recommended to keep them under

controlled condition, 5-30℃, 60%RH and use them within a year.■ 24-hour baking is recommended at 125℃, if unpacked products were kept under

uncontrolled condition, which is 30℃, 60%RH or higher.

Original trays are not heat-resistant. Please move them to heat-resistant trays in preparation

to bake.

To check moisture condition in the pack. Silica gel pacet has some moisture condition

indicator particles.

Indicated blue means good. Pink means alarm to bake it.■ Notification. The tray will be deformed and the power supply might be damaged,

if the vacuum pressure is too much to reseal.

3.9 Stress to the product

■ CHS series transformer core and choke coil are attached by glue.

Thres is a possibility that the core will be removed and power supply will be damaged

when they receive stress by the fall or somekind of stress.■ The base plate at Option"B" and "BC" is attached by glue.

There is a possibility that the base plate will be removed and power supply will be damaged

when they receive stress by the fall or some kind of stress.

6.1 Output voltage adjusting method by external potentiometor

■ Output voltage is adjustable by the external potentiometer.■ When the output voltage adjustment is used, note that the over

voltage protection circuit operates when the output voltage is set

too high.for CHS■ If the output voltage drops under the output voltage adjustment

range, the Low voltage protection operates.■ By connecting the external potentiometer (VR1) and resistors (R1,R2),

output voltage becomes adjustable, as shown in Fig.6.1.1.

Recommended external parts are shown in Table 6.1.1.■ The wiring to the potentiometer should be as short as possible.

The temperature coefficient could become worse, depending on

the type of a resistor and potentiometer. Following parts are recommended

for the power supply.

7.1　Overcurrent Protection

■ Over Current Protection (OCP) is built in and works at 105% of the rated current or higher.

However, use in an over current situation must be avoided whenever possible. The output

voltage of the power module will recover automatically if the fault causing over current is

corrected.

When the output voltage drops after OCP works, the power module enters a "hiccup

mode" where it repeatedly turns on and off at a certain frequency.

7.2　 Overvoltage protection

■ The overvoltage protection circuit is built-in. The DC input should be shut down if

overvoltage protection is in operation.

The output voltage of the power module will recover automatically if the fault causing

over voltage is corrected.

Remarks :

Please note that devices inside the power supply might fail when voltage more than

rated output voltage is applied to output pin of the power supply. This could happen

when the customer tests the overvoltage performance of the unit.

7.3　Thermal protection

■ When the power supply temperature is kept above 120℃, the thermal protection will

be activated and simultaneously shut down the output.

The output voltage of the power supply will recover automatically if the unit is cool down,

● Option "-U"

Option "-U" means output is shut down when the abovementioned protection circuit

is activated.

If this happens, protection circuit can be inactivated by cycling the DC input power off

for at least 1 second or toggling Remote ON/OFF signal.

9.1　When the remote sensing function is not in use

Fig. 9.1.1

Connection

when the remote

sensing is not in use

■ When the remote sensing function is not in use, it is necessary to confirm that pins

are shorted between +S and +VOUT ,and between -S and -VOUT.■ Wire between +S and +VOUT ,and between -S and -VOUT as short as possible.

Loop wiring should be avoided.

This power supply might become unstable by the noise coming from poor wiring.

9.2　When the remote sensing function is in use

Fig. 9.2.1

Connection

when the remote

sensing is in use

■ Twisted-pair wire or shield wire should be used for sensing wire.■ Thick wire should be used for wiring between the power supply and a load.

Line drop should be less than 0.3V.

Voltage between +VOUT and -VOUT should remain within the output voltage adjustment range.■ If the sensing patterns are short, heavy-current is drawn and the pattern may be damaged.

The pattern disconnection can be prevented by installing the protection parts as close

as possible to a load.

■ Output voltage might become unstable because of impedance of

wiring and load condition when length of wire exceeds 40cm.

10.1　Series operation

■ Series operation is available by connecting the outputs of two or more power supplies,

as shown below. Output current in series connection should be lower than the lowest

rated current in each unit.

Fig. 10.1.1

Example of

Series operation

10.2　Parallel operation (CHS400 / CHS500 option "-P")

■ Sensing and adjustment of the output voltage are not possible at the time of the

use with option.

■ As variance of output current drew from each power supply is maxmum 10%, the

total output current must not exceed the value determined by the following equation.

( Output current the Parallel operation )

=( the rated current per unit ) × ( nunber of unit ) × 0.9

When the number of units in parallel operation increases, input current increase

at the same time. Adequate wiring desing for input circuitry is required, such as

circuit pattern, wiring and currentcapacity for equipment.■ Total number of units should be no more than 3 pieces.■ Thick wire should be used for wiring between the power supply and load, and line drop

should be less than 0.3V.■ Connect each input pin for the lowest possible impedance.■ When the number of the units in parallel operation increases,inputcurrent increases.

Adequate wiring design for input circuitry such as circuit pattern, wiring and current for

equipment is required.
