3phase input rectifier 110VDC 20A with output voltage range 100V~155V

NASN POWER RM11020-B3 is an intelligent high-frequency rectifier module designed for critical infrastructure. It operates on a 3-phase 380Vac input range of 330~456Vac, making it adaptable to fluctuating grid conditions. One of its standout features is high efficiency up to 94%, which significantly reduces power consumption and lowers long-term operating costs. With a power factor ≥0.95, it ensures optimized energy usage and minimal harmonic distortion.

Built on microprocessor-based control, the unit supports remote monitoring via RS485, allowing operators to manage systems without physical intervention. It features intuitive LED indicators for alarm and status recognition. Maintenance is simplified through its hot-pluggable design, facilitating future extensions or replacements without shutting down the system. Furthermore, the module includes comprehensive multiple protections—covering over current, over voltage, short circuits, and over temperature—ensuring reliability in demanding environments such as telecom stations or power plants.
