Bel Power Solutions' LDX-B20 microprocessor controlled buffer unit is rated at 20 A and is usable in 12 V, 24 V, 48 V, and 72 V systems. It monitors output voltage from a DC power supply and, in the case of failure, keeps the output regulated for at least 300 ms at full load. This buffer module is just one of many DIN rail accessories available from Bel Power Solutions.

Many systems are subject to power disruptions that can cause failures and data loss. The LDX-B20 can be used where millisecond-to-second backup is required to finish processing during a power disruption. Because of the wide voltage range, this unit is flexible enough to operate within a majority of standard battery output voltages. The LDX-B20 is parallelable for power and backup time increase and at a width of only 63 mm, it will not take up a lot of valuable space in a system.
