Overload Protection
The Power Supply is provided with an overload protection function that protects the load and the power supply from possible damage by over-
current. When the output current rises above a set value (refer to the table below), the protection function is triggered, decreasing the output
voltage. When the output current falls within the rated range, the overload protection function is automatically cleared.

Note:
1. When using the 7.5-W single-output models within the input voltage range between 90 and 110 VDC, the overload protection func-
tion will operate at currents from 95% to 160% of the rated load current.
2. When using the 90-W model at an ambient temperature exceeding 25
"
C, the overload protection function will operate at currents
from 92% to 1 11% of the rated load current.
3. When using the 100-W model with PFC in parallel operation, the overload protection function will operate at currents from 3.78 to
4.2 A.

Note:
Do not short-circuit the output terminals of the S82K or use the S82K with excessive output current for a long time, otherwise the
internal circuitry of the S82K may be deteriorated or damaged.

Output Models
The +V output detects the total output power (+V output and -V output) to trigger the short-circuit protection against overcurrent. This protection
varies depending on the -V output state. The -V output independently triggers the short-circuit protection.
