Overload Protection
The Power Supply is provided with an overload protection function that protects the load and the power supply from possible damage by overcur-
rent. 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 function
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 111% 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.
