L-8

Switch mode Power Supply

S82K

3- to 240-W models without PFC

Note: 1. Defined with a 100% load and the rated input voltage (100 or 200 VAC).

2. The output specification is defined at the power supply output terminals.

3. The settings for the output voltage must be within the following range:

+V:

±1% of the rated value

−V: ±5% of the rated value

4. When using the 7.5-W single-output models within the input voltage range between 90 and 110 VDC, the protection function will operate

at a current of 95% to 160% of the rated load current.

5. When the ambient temperature exceeds 25

°C, the protection function will operate at a current of 92% to 111% of the rated load current.

6. Circuit-breaker type. To reset, turn the input power supply OFF, then after 1 min has elapsed, turn the input power supply ON again.

7. Parallel operation is set with the Parallel/Single Operation Selector Switch. (This setting is not required for S82K-10024 models.)
