Features, Applications

The is a microprocessor controlled buffer unit rated 20 A usable 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 ms at full load.

Wide voltage range - 85 VDC Compact size DC BUS voltage self-tracking Boost Max peak power of DC supply Multiple protections Digital regulation Reliable topology, based on standard electrolytic capacitors > 150 Joules energy storage Integrates low power step-up (boost) converter to charge the capacitor bank Integrates 20 A step-down (buck) converter to discharge the capacitor bank at an adjustable output voltage in case of mains failure Relays dry contact and an opto-isolated input for inhibit Integrated safety circuit that disconnects the capacitor bank in case of internal failure Parallelable for power and backup time increase
