Product description
The SI48-1U-8-2 DC power system provides a stable 48 V DC power supply to devices. It offers an output current of 8 A and a power output of 400 W. The unit is housed in a standard 19″ rack-mount chassis with a height of 1U, which facilitates installation in telecommunications cabinets. The DC power system supports two battery packs and can also operate without batteries connected. Microprocessor-based control ensures precise float voltage regulation with temperature compensation and provides accelerated battery charging with current limiting. The RS232 interface enables communication with the device and remote monitoring of its operation. Automatic cooling enhances operational reliability, while visual, audible, and remote alerts notify users of alarm conditions. The digital display shows voltages, currents, and temperature, facilitating real-time monitoring of operating parameters. The operating temperature range of -33°C to +70°C ensures reliable operation in demanding conditions.
