- Communications (FARM type) (FARM-50NHE, 30N, 50N
FARM-75, 100) - High-efficiency, high-density DC power supply for Base station and Relay Base-Station
Rated output voltage: -54V / +27V
Overview
It is a device that supplies DC power to base station and relay base station for communication.
As a modular format, it is 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.
- Rack type modular
- For small cell wireless communication base station
- Output current range: Difference by product specification (30A / 50A / 75A / 100A)
- Small and lightweight module production
- Efficiency: over 90% (rated input 50-100% load)
- Output stability according to load change: within ±1% of output voltage (10~100% load)
- Surge: input reference voltage 6 ㎸ (1.2 X 50 ㎲), current 3 ㎄ (8 X 20 ㎲)
- Overheat protection cutoff: output cutoff within rectifier module internal heat sink temperature 95℃ ± 10℃
Specification
It can be customized according to customer requests, such as rated output voltage and maximum output current, etc.
