Power buffer modules deliver extra 380ms hold-up in an open frame package
TDK-LAMBDA ZBM20 series 12V, 15V and 24V 20A rated open-frame buffer modules provide an extended 380ms hold-up time to power supplies preventing data loss during brief power interruptions or allowing equipment to safely shutdown. Energy is stored in electrolytic capacitors, replacing the need for batteries and their associated maintenance and servicing. A remote on/off function can be activated to avoid an unsafe discharge of stored energy. The charge and discharge status can be monitored locally or remotely via a DC OK relay, an LED indicator and photo-coupled signals. Measuring 175 x 85 x 57mm (L x W x H), units operate without derating in ambient temperatures of -25°C to +70°C. Applications include industrial automation, robotics, test, communication and semiconductor fabrication equipment.
