DBM20: 24 V / 20 A buffer module
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.
- DIN rail housing with only 49 mm width - more space on the DIN rail
- 250 ms hold-up time at 448 W load - Prevents data loss during power failures
- Uses electrolytic capacitors for energy storage - No batteries to maintain
- Can be paralleled - Hold time can be easily extended
- Remote output on/off function - Prevents unsafe discharge of stored energy
