3. Terminal Connection Method
Pay attention to the input wiring. If it is connected to wrong terminal, the power supply will be damaged.
Input must be off when making connections.
Connect terminal of input connector and mounting hole to protective earth of the equipment.
The output load line and input line shall be separated to improve noise sensitivity.
Do not apply stress to PCB, when connecting or removing connector.
Do not apply stress to other components (especially VR51 and C51), when connecting or removing connector.
Use input/output connector (housing) specified by the table below.
Use recommended crimping tool. Connector is not included with this product. (Refer to the following)
Input/Output Connector

Output ( CN51 )
ZWS10B, ZWS15B
Output ( CN51 )
Hand Crimping Tool : YC-160R (J.S.T.)
4．Explanation of Function and Precautions
4-1. Input Voltage Range
Input voltage range is single phase 85-265VAC (47-63Hz). Never operate the unit out of the specified input voltage range to avoid unit
failure.
For cases where conformance to various safeties required, input voltage range will be 100-240VAC (50/60Hz).
4-2. Output Voltage Range
Output voltage is set the rated value at shipment. V.ADJ trimmer (VR51) can adjust the output voltage within the range. Output voltage range
is within ±10% of nominal output voltage. To turn the trimmer clockwise, the output voltage will be increased. Take note when the output
voltage is increased excessively, over voltage protection (OVP) function may trigger and voltage will be shut down. Furthermore, when
increasing the output voltage reduce the output current so as not to exceed the maximum output power.
