Cin is shown in Table.. mm Measuring board DC Input Cin + Co Load Function. Overcurrent protection Over Current Protection (OCP) is built-in and works over % of the rated current or higher. However, use in an overcurrent situation must be avoided whenever possible. The output voltage of the power module will recover automatically when the fault causing overcurrent 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.. Overvoltage protection The overvoltage protection circuit is built-in. The DC input will be shut down if overvoltage protection is in operation. The output voltage of the power module will recover automatically when 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.. Thermal protection When the power supply temperature is kept above C, the thermal protection will be activated and simultaneously shut down the output. The output voltage of the power supply will recover automatically when the unit is cool down. -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 second or toggling Remote ON/OFF signal..

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 cm.. Adjustable voltage range () To adjust output voltage 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. If the output voltage drops under the output voltage adjustment range, the Low voltage protection operates. By connecting the external potentiometer (VR) and resistors (R, R), output voltage becomes adjustable, as shown in Fig... Recommended external parts are shown in Table..

Parallel operation Power + Supply - Fig.. Examples of series operation -P (CHS,CHS) This option is for parallel operation. Sensing and adjustment of the output voltage are not possible at the time of the use with this option. As variance of output current drew from each power supply is maximum %, the total output current must not exceed the value determined by the following equation. Load Load (Output current in parallel operation) =(the rated current per unit) x (number of unit) x.9 When the number of units in parallel operation increases, input current increase at the same time. Adequate wiring design for input circuitry is required, such as circuit pattern, wiring and current capacity for equipment. Total number of units should be no more than pieces. Thick wire should be used for wiring between the power supply and load, and line drop should be less than.v. 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.

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.

As shown in Fig.., avoid applying stress of more than 9.N (kgf) to the pins horizontally and more than 9.N (kgf) vertically. The pins are soldered on PWB internally. Therefore, do not pull or bend them with strong force. Fix the unit on PCB (using silicone rubber or fixing fittings) to reduce the stress to the pins. 7 Safety Considerations 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 insulation 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.
