Superseder II

INTRODUCTI ONThe superseder II Battery charger/Analyzer is basicalry aprograhmable consLant currenL source for charging and a constanLcurrent sink for discharge, using scR's with phase choppingfor the charge and a transistor linear road for discharge.The duration of the charge and discharge cycles i\re autonaticallyconLrorled by presettabre digitar Liuers, programuablein hours or minutes (or seconds in the tesL cloct< mode).The charge and discharge cycles are also terminated automaticallyas a function of the battery voltage. A cell selectorprograEs the discharge cuL-off vortage at the equivarenL of1.00 volL/cerr and an overvortage charge cut-off at the equivalentof L.7O VoIts/cell.A monitor circuit verifies proper operation and shuLs offthe insLrumenL if an abnormal condition is detected. Conditionsbeing monitored include current tracking (actual vs programnred)battery overtemperaLure (through an externar prate), reversepolarity, open circuit and discharge road bank overheating.A conLrol switch selects the operating mode, while aseries of indicator Iights ahow the operating status.Two digital Panel meters are used to indicate current flowand battery voltage. Ttre voltmeter can also be selected to measureexternal volLages.page 2 - Superseder II - Technical Manual, rev 0
