DC Guardian Power System for Power Applications
5 kW Bidirectional High-Frequency Isolated DC-DC Power Module
IBDC50100
5 kW Bidirectional High-Frequency Isolated DC-DC Power Module, supporting three operating modes: Charging, Discharging, and Automatic Switching. In the event of bus voltage loss, the module automatically switches to guard mode. Battery voltage range: 45–65 Vdc; DC bus-side voltage range: 187–264 Vdc; Specifically designed for 220 V DC guard power systems.
