Note: 1. Use with DC voltage input is beyond the conditions of approval or conformance to applicable safety standards.
2. Use the 7.5-W single-output models under the load of 90% max. if the voltage range is between 90 and 110 VDC.
3. Defined with a 100% load and the rated input voltage (100 or 200 VAC).
4. The output specification is defined at the power supply output terminals.
5. The settings for the output voltage must be within the following range:
+V: r1% of the rated value
–V: r5% of the rated value
6. 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. When using the 90-W model under the ambient temperature over
25qC, the protection function may operate at a current of 92% to 111% of the rated load current.
7. Circuit-breaker type. To reset, turn the input power supply OFF, then after 1 min has elapsed, turn the input power supply ON
again.
8. Do not press down on the terminal block with a force exceeding 75 N while tightening the terminals.
9. To ensure the emission ratings, a noise filter should be used on the output lines at the closest point.
(3- to 50-W models: S82Y-JF3-N, 90-W and 100-W models: S82Y-JF6-N)
10. To ensure the Emission Enclosure rating, a ferrite ring core should be used on all cables (for S82K-P24024).
11. To meet Class 2 requirement with 100-W model, either a fuse or circuit breaker that is UL listed or CSA certified, and rated at
4.2 A max. should be used in the output of the power supply. Only then can the power supply output be considered as meeting
Class 2.
