Product description
The SI24D-2U2-252-ET DC power system provides a stable 24 V DC power supply to equipment. It offers an output current of 50 A and a power output of 1200 W. The unit is housed in a standard 19″ 2U rack-mount enclosure, which facilitates installation in telecommunications cabinets. The telecommunications power supply unit is equipped with two hot-swappable rectifiers that can be replaced without interrupting system operation. The device has 4 slots for optional modules (DC/DC converters or DC/AC inverters). It supports two AGM batteries and, optionally, LiFePO4 batteries. Microprocessor-based control ensures precise regulation of power supply parameters, and an audible alarm signals any alarm conditions. USB, RS-485, and Ethernet interfaces with web and SNMP support enable local configuration and remote monitoring of the device’s operation. An efficiency exceeding 93% and an operating temperature range from -33°C to +70°C guarantee reliable operation in demanding conditions.
