Product description

The ZM48V3A-151AZC power supply is a 48 V floating-operation power supply with battery circuit resistance measurement and RS232 or RS485 digital communication, designed for automation, power engineering, and telecommunications. It ensures compatibility with batteries in buffer mode and uninterrupted power supply in the event of a failure. The buffered power supply remotely signals a failure of the backup power source. Additional LEDs can be connected to the power supply to indicate a mains failure and a general fault signal. The low-power version (151) provides a nominal output current of 3 A. Full compliance of the power supply with the requirements of PN-EN 54-4 + A2 and PN-EN 12101-10 is achieved when installed in an IP30 enclosure equipped with a battery bank. External dimensions: 66x111x203+17 (connectors).
