4.8 DC_OK signal

An open collector output provides a low output voltage detection signal. The open collector output is on when the output voltage is higher than 80%+/-5% of the rated output voltage of the power supply.

The open collector output is referenced to the Signals_Return potential and is isolated from the power supply +V and -V terminals

The maximum sink current is 10mA and the maximum external voltage is 15V. Refer to Fig 4-3 for typical application.

4.10 Remote On/Off control

A Remote On/Off control input is provided. The Remote On/Off input is isolated from the power supply +V and -V terminals and is referenced to the Signals_Return potential. The Remote On/Off can be operated either by electrical signal or by dry contact.

(1)Operation by electrical signal: 0~0.6V: Output is On. 2~15V: Output is Off.

The maximum sink current is 2.6mA and the maximum external voltage is 15V.

(2) Operation by dry contact (relay or switch):

Short between On/Off input and Signals Return: Output is On.

Open circuit between On/Off input and Signals Return: Output is Off.

When the Remote On/Off function is not used, connect a short circuit between the On/Off control and the Signals_Return. Refer to Fig 4-5 for the remote On/Off circuit description:
