The La Marche model A75MD mine battery charger product line utilizes microprocessor controlled SCR charging technology. The A75MD comes with a Vacuum Fluorescent Display (VFD) which is bright with clear contrast and functions normally from -40°C to 80°C, making them ideal for outdoor use.
This charger features automatic AC line voltage compensation, current limiting, controlled I-E-I charging cycle and more. The I-E-I charge cycle provides constant current start charge rate followed by constant voltage and completing with constant current finish rate. The constant current finish rate can be terminated either by DV/DT or time to assure full charge.
