Product Description

Product introduction

Sanhe LDVR is an inverter based system that protects sensitive industrial and commercial loads from voltage disturbances. It is optimally designed to provide equipment immunity from power quality events on the Alternative current system .

Feature
No energy storage needed
By-pass working mode
Electrical isolation for overhauling and maintenance
Voltage sags and swell correction, even with regenerative loads
Rugged overload capability
Fault log and voltage event data logging
Ethernet/RS485 connectivity
Modular construction
User-friendly experience design

Product Description
Voltage sags is quite popular in the AC supply system, specially caused by large load changes,motor, compressor, cap.bank starting etc. The short circuit faults in the distribution and transmission grid or at a neighbouring load, which are caused by lightning, storms or overhead lines problem, physical damage to the grid etc. bring voltage sags. Voltage sags impact the peoples life and industrial production. Sanhe LDVR is a good solution to correct voltage sag and swell.

Product Solution Selection
In the market, there are three types of voltage stabilization,automatic voltage regulator, automatic voltage conditioner(without energy storage), dynamic voltage restorer(with energy storage). The main difference is in full response time, short interruption treatment. The price is quite different. Anyhow,we can give you a suitable voltage treatment solution.
