DBM20
NEW RANGE24Vdc 20A DIN rail mount buffer module
The DBM module is ideal for providing short term hold-up or peak power for loads connected to a 24Vdc output AC-DC power supply. It can supply an additional 250ms hold-up at 448W output power.
During normal operation, energy is stored in the DBM20’s electrolytic capacitors. When the AC power is interrupted for a short period of time, the DBM20 continues to power the load, allowing equipment to shut-down in a safe and controlled manner. The DBM20 can be set to fixed or variable buffer mode. In fixed mode it will provide power when the input voltage drops to 22.4V, in variable mode when the input decreases by 1V. Multiple buffer modules can be paralleled for additional hold-up time. Product status can be accessed remotely via a DC OK relay, or locally using the LED indicators. The output voltage can also be inhibited to avoid an unsafe discharge of the stored energy.
