Function 2.1 Overcurrent protection Overcurrent protection circuit is built-in to be operated over 105% of the rated current. ¡ This function works to protect against short circuit and overcurrent condition of less than 20 seconds. When cause of activation of overcurrent protection is removed, the output will be automatically recovered. The power supply which has a current foldback characteristics may not start up when connected to nonlinear load such as lamp, motor or ¡ constant current load. See the characteristics below. Z : Load characteristics of power supply : Characteristics of load (lamp, motor, constant current load, etc.) Note: In case of nonlinear load, the output is locked out at A point. Fig. 2.1 Current foldback characteristics 2.2 Isolation ¡When conducting tests such as the Hi-Pot test at an incoming test, gradually increase the voltage. Also, gradually reduce the voltage for shut down. Avoid using the Hi-Pot tester with timer because it may generate the voltage a few times higher than the applied voltage when the timer starts and ends. 18 3. Wiring to Input/Output Pin Input filter is built-in. By external capacitor Ci closer to the input terminal, input connected noise from converter can be reduced by forming ¡ the π type filter. Since operating frequency is high, select the capacitor with high frequency type. ¡Install Ci at input terminal when the line from source to converter is long. When Ci is not installed, it may unstabilize the output, it makes input feedback noise big and several times voltage of input voltage is applied. Moreover, install Ci at input terminal if abnormal voltage from input power supply like surge is drawn.

Series Operation and Parallel Operation 4.1 Series operation ZS1R5/ZW1R5• ZS3/ZW3• ZS6/ZW6 ¿ Series operation is available by connecting below. However, output current in series connection should be lower than the lowest rated ¡ current in each unit. But at series operation with same output voltage, diode is not required to attach even if at (a). (a) (b) D1, D2: Please use Schottky Barrer Diode which has lower forward voltage. ¿ZS10/ZW10 ¡Series operation is available. However, output current in series connection should be lower than the lowest rated current in each unit. 4.2 Parallel redundancy operation Parallel redundancy operation is available by connecting below. ¡ Values of I1 and I2 might be slightly different because of fine differences of output voltage. Keep balance of output current, as output ¡ current from each power supply should not exceed the rated current value. I1, I2 * the rated current value Z 5. Assembring and Installation Method 5.1 Installation method ¡The unit can be mounted in any direction. Position them with proper intervals to allow enough air ventilation. Ambient temperature around each power supply should not exceed the temperature range shown in delating curve. Avoid placing the DC input line pattern layout underneath the unit because 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. 20 Fig. 5.1 Pattern wiring 5.2 Derating By derating the output current, it is possible to operate the unit from -10ª~+60ª for ZS(W)1R5~ZS6 and from -10ª~+70ª for ¡ ZS(W)10. ¡When unit mounted any way other than in drawings below, it is required to consider ventilated environments by forced air cooling or temperature/load derating. For details, please consult our sales or engineering department. Except ZS(W)10 ZS(W)10 ¡The temperature increase of case surface at full load is shown by below table as referenced data.

Input Voltage/Current Range When a non-regulated source id used as a front end, make sure that the voltage fluctuation together with the ripple voltage will not exceed ¡ the input voltage range.

Water type 2 Clean Through 750H(KAO Corporation) 3 IPA Solvent type 4 Asahiklin AK-225AES(ASAHI GLASS CO.) Z Cleaning period ¡ The total time of varnishing, ultrasonic wave and vapor should be within 2 minutes. In case of ultrasonic wave cleaning, the ultrasonic should be less than 15W/R. During cleaning to drying (the condition that cleaning liquid is soaked into the ink of name plate), do not touch on the surface of name plate. ¡After cleaning, dry them enough. 8. Soldering ¡Flow soldering : 260ª less than 15 seconds. ¡Soldering iron : 450ª less than 5 seconds. 22 9. Input/Output Pin ¡When too much stress is applied on the input/output pins of the unit, the internal connection may be weakened. As below Fig. 8.1, avoid applying stress of more than 1kgf on the pins horizontally and more than 2kgf vertically. ¡The input/output pins are soldered on PCB internally, therefore, do not pull or bend them with abnormal forces. ¡When additional stress is expected to be put on the input/output pins because of vibration or impacts, fix the unit on PCB (using silicone rubber or fixing fittings) to reduce the stress onto the input/output pins. Fig. 8.1 Stress onto the pins 10. Peak Current (Pulse Load) ¡When converter is used for pulse load, there is a way to supply pulse current by connecting the capacitor externally at output.
