Solutions of remote power supply for the coverage along the highway, high-speed railway

The program for power supply system

Supply remote 220vac along with -48vdc communication power.

Mains is normal: supply 220vac power for remote load.

Mains is abnormal: invert -48vdc to 220vac to remote load.时期

With the features of high efficiency and safety, one device can provide power for several RRU, this is good for installation and after-sale service. Meanwhile, the AC power supply program decrease the cost effectively.
