LDX-B20 Series | Bel Power Solutions

Application

The LDX-B20 is a microprocessor controlled buffer unit rated 20 A usable in 12 V, 24 V, 48 V and 72 V systems.

The LDX-B20 monitors the voltage coming from a DC power supply and in case of failure a capacitor bank is used to keep the output regulated for at least 300 ms at full load.
