Coefficient %/ºC ogic/analog Signals Remote Control Power Good Remote Sense On/Off control of output. A low signal(<.v) disables output. It defaults to normal output when there is no connection to this pin. Goes high - ms after the output reaches regulation. It goes low at least ms before loss of regulation. Remote sense terminals force regulation to where sensing terminals are connected. Return for logic signals, same as output ground. Fan Drive FanDrive Provides V, ma to drive a DC fan. Protection Circuits Overload Output Over-voltage Short Circuit Input Under-voltage Over temp. Current limiting starts at % of the rated output current and recovers automatically. Output is protected against overvoltage. Unit shuts down at -4% of rated voltage. Protected. ong term short circuit may reduce reliability. Power supply shuts down when ac input is under 8 VAC. When ac line reappears over 86 +/- VAC, the power supply restarts automatically. Power supply shuts down when temperature is in excess of 8 ºC. Auto recovery.
