• Wide mains input variation tolerance
• Fast acting electronic protections for charger, battery and load
• Automatic Float/Boost charging modes
• Appropriate metering, annunciation and alarms
• Special models with wider input sustainable design
• No break output for load in case of mains failure
• Design characterized by requirement of least attendance of user
• Epoxy powder coated wear resistant cabinet
• All PCB`s with solder masking and legend printing
• 100% incoming Q.C. checked active devices
• 100% outgoing Q.C. checked and heat run tested
• Output protected against overload and short circuit.
• Over voltage protection at output by fast acting electronic trip circuit [with manual reset]
• Protection against reverse polarity of battery, provided by diode fuse combination.
• Input protected by fuse of appropriate rating.
• Input Voltage: 160 to 270 V R.M.S. 50/60 +/- 3Hz single phase AC
• Output Voltage: 52 Volts DC [nominal]
