Overviews

Emerson HD4825-3/HD4830-3 provides the core components of the DC 48V system for power to cooperative manufacturers. Cooperative manufacturers can use this component to form a 48V DC system with a certain capacity configuration, which can be used in power plants, hydropower stations, various substations and other occasions that require communication power.

 

Communication power supplies HD4830-3, HD4825-3, and HD4810-3 are developed using modern power electronics and industrial control technology, built-in advanced microprocessors, and adopt comprehensive soft-switching technology. The efficiency and EMC have reached the industry's first-class level.

 

Features

1. Emerson's communication power supply adopts active power factor compensation technology, with a power factor value of 0.992. The normal working range of the AC input voltage of Emerson communication power supply is as wide as 90~290V. When the voltage is as low as 170V~180V, the rectifier module will limit the power output and the return difference is less than 10V.

3. Emerson's communication power supply adopts comprehensive soft-switching technology with an efficiency of over 91%4. Emerson's communication power supply adopts non-destructive hot-swappable technology, plug and play, and the replacement time is less than 1min

5. Emerson's complete fault protection and fault alarm function of communication power supply

6. Emerson communication power supply has ultra-low radiation, safe and reliable
