1. Overview:
This is an indoor use pure RLC load bank LB-640KVA-AC400V-J.
The load testing system is composed of two parts: the loads and the control system, which mainly include alloy resistors, shunt reactors, capacitors, gear contactors, PLC, protection system, heat dissipation device, auxiliary control. All the elements are packaged in an enclosure, can be used indoor and outdoor.
