- Communications (NARM-200NHE)
- High-efficiency, high-density DC power supply for Base station
Rated output voltage -53.5V
Overview
It is a device that supplies DC power to large communication devices.
As a modular format, it can be mounted max 10 modules on the rack and easy to repair and can adjust current range.
With hot-swap method, it can be repaired without power off and enable continuous operation in case of power failure through the batteries.
It can be displayed with the control keys PAD and LCD.
