Factory Direct Supply R4875G1 Rectifier Module -40℃~+75℃ Working Range Peak Efficiency up to 97% Power Supply Module

Product details

Ultra-Wide 85-300VAC Single Phase Wide Input Voltage: Supports 85V to 300V alternating current wide input range, adapting to unstable rural and remote mountain power grids. No extra voltage stabilizer needed, compatible with most global commercial power grids, reducing auxiliary equipment investment for telecom project deployment and simplifying on-site construction.

Industry-Leading 97% Peak Conversion Efficiency Energy Saving: Optimized internal power circuit architecture raises peak conversion efficiency to 97%. It greatly reduces idle and full-load power consumption compared with old generation rectifiers. Lower heat generation cuts fan power loss, helping telecom operators lower long-term electricity operation costs of communication machine rooms.

Adjustable 42V-58V Wide DC Output Voltage Range: DC output voltage continuously adjustable between 42V and 58V via system monitoring unit. It perfectly matches charging voltage requirements of lead-acid batteries and lithium iron phosphate batteries widely used in communication power systems, flexible for various energy storage and backup power design schemes.

Comprehensive Multi-Layer Full Electrical Safety Protection Circuits: Integrates overvoltage, undervoltage, overcurrent, short-circuit, over-temperature, reverse battery connection multi-protection circuits. Once abnormal operating status occurs, the module automatically locks output to protect internal core components, storage batteries and downstream communication loads from permanent damage.

Ultra-Wide Working Temperature -40℃ ~ +75℃ Harsh Environment Adaptation: Designed for extreme indoor and outdoor temperature environments, stable normal operation from -40℃ low temperature to +75℃ high temperature, no power derating below 55℃. Suitable for unattended outdoor base station cabinets, alpine, desert and tropical communication sites without extra temperature control auxiliary devices.
