Introduction:

The A70B is an industrial battery charger which uses SCR technology and provides dependable and precise battery charging with easy to use, selectable and preprogrammed functions. The A70B allows you to select the required input voltage with simple transformer tap changes: La Marche A70B Battery Chargers conform to CSA, UL, OSHA, NEMA and FM standards of performance, durability and safety. Except for the AC input contactor which provides line isolation safety, there are no voltage-sensitive relays or moving parts that need continual servicing and maintenance. Special microprocessor programming is used to minimize contactor wear.

Since 1945, La Marche has been providing reliable power conversion products. La Marche products include industrial battery chargers, rectifiers, power supplies, inverters and more. La Marche is an ISO 9001:2008-certified manufacturer which includes 100% functional testing for every La Marche product. La Marche has built its reputation by controlling all aspects of the development process including design, in-house manufacturing and testing.

La Marche has been serving the material handling industry for nearly 70 years with high quality, rugged & dependable battery chargers. La Marche offers industrial motive power battery chargers in four different technologies; including Ferroresonant, Controlled Magnetic Amplifier (Mag-Amp), Silicon Controlled Rectifier (SCR) & High Frequency (Switch Mode). Each of these technologies has feature/cost advantages which can serve many battery/equipment requirements.
