Access 50 is a 3-phase charger with capacities up to 5 kW. The charger can be powered by all commonly existing mains voltages and many of the models are certified to UL and CSA standards for use in the USA and Canada by Underwriters Laboratories. The Access charger from Micropower provides you with powerful and energy efficient battery charging. The modern state of the art MOSFET power conversion circuit efficiently and accurately converts AC power to the proper DC power levels required to charge different kinds of industrial batteries. Every Access charger can be set to perform both conventional charging and various levels of opportunity charging. There are several different charging curves available, such as for ionic mixing and opportunity charging, preprogrammed into every Access charger.
