DBM20 – 24 V 20 A DIN rail hold-up module

TDK-Lambda announces the introduction of the DBM20 DIN rail mount 24 V 20 A buffer module. The buffer module is ideal for providing short term hold-up or peak power for loads connected to a 24 Vdc output AC-DC power supply. It can supply an additional 250 ms hold-up at 448 W output power, or 2 s with a 2.5 A load. The extended hold-up time allows equipment to safely shutdown and avoid data loss during AC power interruptions. Applications for the module include industrial automation, robotics and semiconductor fabrication equipment.

A remote on/off function to avoid unsafe discharge of stored energy, a DC OK relay, LED indicators and photo-coupled signals indicating fully charged and discharging modes are fitted as standard. Multiple modules can be paralleled for longer buffer times. Energy is stored in electrolytic capacitors, avoiding the need for servicing and maintenance of batteries. A front panel accessible switch can be used to select either fixed or variable voltage buffer levels. In fixed mode, it will provide power when the input voltage drops to 22.4 V, in variable mode when the input decreases by 1V.

Measuring just 49 x 123.6 x 115.4mm (WxHxD), the units will operate in ambient temperatures ranging from -25°C to +70°C. The five-year warranty DBM20 has protection against both input overvoltage and overcurrent conditions. Inrush current reduction and internal fuses are also provided. Safety certification includes IEC/UL/CSA/EN 62368-1, UL 508 with CE marking to the Low Voltage, EMC and RoHS Directives.
