Product description

The ZEM40-D-RS485 floating-operation power supply is designed to power telecommunications equipment and power systems. It offers two 24 V DC outputs—a buffer output and an output with a time-delay shutdown function. Microprocessor-based control ensures stable operation and supports a 7 Ah battery in buffer mode. A 0.3 A charging current and a minimum cut-off voltage of 21 V protect the battery from excessive discharge. LED indicators show the device’s operating status and any errors. Additional outputs enable remote signaling of selected power supply statuses. The RS485 communication interface allows for remote monitoring of the power supply's operating parameters. The metal enclosure with an IP20 protection rating is designed for mounting on a TS35 DIN rail. The buffer power supply operates over a wide temperature range from -25°C to +70°C.
