Auxiliaryvoltageoutput,4.6~5.25V,referencedtopin3(G-AUX). Themaximumloadcurrentis0.5A. Thisoutputhasthebuilt-inoring
diodesandisnotcontrolledbythe"remoteON/OFFcontrol".
Opencollectorsignal,referencedtopin11,12(GND).LowwhenPSUturnson. Themaximumsinkcurrentis10mA andthemaximum
externalvoltageis 5.6V.
Currentsharingsignal.Whenunitsareconnectedinparallel,theCSpinsoftheunitsshouldbeconnectedtoallowcurrentbalance

Negativesensing. The-Ssignalshouldbeconnectedtothenegativeterminaloftheload. The-Sand+Sleadsshouldbetwistedinpairto
minimizenoise pick-upeffect. Themaximumlinedropcompensationis0.5V.
