A75MD
Mine Battery Charger (SCR)
SCR Technology Mine Battery Charger
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.
The rugged A75MD is specially designed for the mining market to perform reliably under severe conditions such as
moisture, corrosive atmosphere and rugged handling. The unit is convection cooled utilizing a 180°C class H insulation
system and powder coat paint for durable finish.
