3. Connecting method
Pay attention to the input wiring. If it is connected to wrong terminal, the product will be damaged.
•
Input must be off when making connections.
•
Connect terminal to earth (frame ground of the equipment etc.) by thick wire for safety and improvement
of noise sensitivity.
• 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.
• Use input/output connector (housing) specified by the table below.
• Use the terminal pin SVH21TP1.1 or BVH21TP1.1, when output current per connector pin is 5A or less.
• Use the terminal pin SVH41TP1.1 or BVH41TP1.1, when output current per connector pin is 7A or less.
• Use recommended crimping tool. Connector is not included with this product.

4. Explanation of Functions and Precautions
41. Input Voltage Range
Input voltage range is single phase 85265VAC (4763Hz).
Input voltage, which is out of specification, might lead the product damage. For cases where conformance to
various safeties required, described as 100240VAC (5060Hz).
Output derating is required for AC input voltage less than 90VAC.
42. Output Voltage Range
Output voltage is set at the rated value. Output voltage within the range specified can be adjusted by V.ADJ
trimmer. Please set output voltage within specified adjustable range.
Turning 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 as not to exceed the maximum
output power.
When the trimmer turns quickly at no load condition, the output voltage might become unstable. To maintain
the output voltage stable, flow the output current, or remove the input of the product until the output be shut
down, and then reinput. Please turn the trimmer slowly during the output voltage adjustment.
