Product description

The SI48D-2U5-153-ET DC power system provides an output voltage of 48 V DC, a current of up to 45 A, and a power output of 2,400 W. Its modular design allows for easy system expansion and quick replacement of rectifier modules using hot-swap technology without shutting down the device. The DC power system can operate on either AC or DC voltage, which increases application flexibility. High efficiency exceeding 90% and voltage regulation of 0.6% guarantee a reliable power supply to connected devices. The model supports up to two batteries and nine output circuits. The RS485 and Ethernet interfaces allow for configuration and monitoring of the unit’s operation. Overload and temperature protection features enhance operational safety, and the memory stores a history of over 1,000 events. The unit’s design, adapted for installation in a 2U/19" rack, facilitates integration with telecommunications cabinets.
