Thanks to thisfeature, it is not required to carry the DC supply fromthe battery to the transfer panels, providing ease ofinstallation.The unit monitors 3-phase mains voltages, sendsremote start command to the generating set andperforms changeover of both generator and mainscontactors.The front panel leds provide information about mainsand generator power availability as well as contactorpositions. Moreover, mains phase voltages andfrequency can be seen on front panel.Mains voltage and frequency high and low limits,mains waiting timer, mains fail timer, generator startdelay, cooldown timer and mains contactor timer arefront panel programmable. Generator contactor timeris adjustable between 1 and 40 seconds through frontpanel knob.DIN Rail mountedNo DC supply requiredMains phase order checkAdjustable MCB and GCB delaysProgrammable mains frequency and voltage highand low limitsProgrammable delay timers10A/250VAC MCB and GCB outputs10A/28VDC remote start outputIsolated mains and genset inputsTest modeFEATURESDESCRIPTION
