CUI Inc

│ SERIES: VOF-300 │ DESCRIPTION: AC-DC POWER SUPPLY

On/off Remote Control

A PS On/Off remote control is provided in CN4. See Figure 1 for the PS-ON diagram and control function.

APPLICATION NOTES

Figure 1

Note: Power on: V

(PS-ON and GND short, I

Power off: Open circuit, V

When the PS On/off remote control function is not

used, connect a short circuit between the PS-ON

control & the signal GND.

Output Remote Sensing

The VOF-300 series can remotely sense both lines of the output. The feature moves the effective voltage regulation point

from the output of the unit to the point of connection of the remote sense pins. This feature automatically adjusts the real

output in order to compensate for voltage drops in distribution and maintain a regulated voltage at the point of load. The

remote sense voltage range is as follows:

[(+Vout) – (-Vout)] – [(+Sense) – (-Sense)] ≤ 10% Vo_nominal

If the remote sense is not used, the sense pins should be connected locally to the respective Vout pins. The remote sense pins are located

on CN4.
