FEAS Accupacks LDR4012 and LDR4024 charging regulators

The FEAS Accupacks LDR4012 and LDR4024 charging regulators buffer 12 and 24 V systems, connecting between the line voltage and an electrical installation to provide DC to equipment. In the event of a mains power failure, the onboard sealed batteries supply power to equipment connected to the outlet. The supply duration depends on the load current of the consumer. The batteries can be easily replaced, if necessary.

A built-in switchmode power supply provides the needed power and to maintain a wide input voltage range of 85-270 VAC and 150-400 VDC.

An AC/DC converter supplies the accumulator with optimal charging voltage as well as the output load so that, under normal operation conditions, the batteries are always properly charged.

The output voltage follows the battery voltage. In both normal and emergency operation modes, full load can be drawn from either unit. For a limited period, the peak current could exceed the nominal current up to 50%. The output is protected against short-circuit and polarity failure. Two built-in relays allow remote monitoring of the LDR status.
