Fail-safe power supplies for unsecured power nets PLG - Accumulator buffered power supply 24 V power supply unit with accumulator buffering Usable for lead and gel accumulators with capacities of 1.2 Ah up to 38 Ah Output voltage is independent of the state of charge of the accumulator Short circuit and overload resistance of the output current High efficiency by microcontroller supported loading and unloading of the accumulator Integrated deep discharging and reverse-connect protection for the accumulator Higher accumulator life time by an optional temperature sensor Operating and state of charge supervision by LEDs and potential-free contact Mounting on DIN rail

PLG - Accumulator buffered power supply General system description PLG The buffered dc power supply of the type PLG uses external lead or gel accumulators for the storage. At an available line voltage the PLG makes the output voltage UA available and charges the accumulator or keeps its charge. The load current is independent of the state of charge of the accumulator .
