The ZBM20 series provides 380-millisecond hold-up time to prevent data loss during brief power interruptions or enabling equipment to shut down safely.

SAN DIEGO – TDK-Lambda Americas Inc. in San Diego is introducing the ZBM20 12-, 15-, and 24-=volt 20-amp rated open-frame buffer power electronics modules for robotics, test, communications, semiconductor fabrication equipment, and industrial automation.

The ZBM20 series provides an extended 380-millisecond hold-up time to power supplies to prevent data loss during brief power interruptions or enabling equipment to shut down safely.

These power electronics devices store energy in electrolytic capacitors, replacing the need for batteries. Users can activate a remote on/off function to avoid an unsafe discharge of stored energy.

Users can monitor the charge and discharge status locally or remotely via a DC OK relay, an LED indicator, and photo-coupled signals. Designers can connect modules in parallel for longer hold-up times.

The 24-volt model has a switch that can select either fixed- or variable-voltage power buffer levels. In fixed mode, it will provide power when the input voltage drops to 22.4 volts; in variable mode when the input decreases by one volt.

The power module measures 175 by 85 by 57 millimeters, and will operate without derating in ambient temperatures of -25 to 70 degrees Celsius. The five-year warranty protects against input overvoltage and overcurrent conditions, has inrush current reduction, and internal fusing. Safety certification includes IEC/UL/CSA/EN 62368-1 with CE marking to the Low Voltage, EMC and RoHS directives.
