See Figure 1 for the PS-ON diagram and control function. Figure 1 VOF-300 Note: Power on: VPS-ON 2V, IPS-ON 2 mA (PS-ON and GND short, IPS-ON = 4.5 mA typical) Power off: Open circuit, VPS-ON = 11~16 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.
