Electronic voltage regulators mainly consist of isolation transformers, contactors, CPU control cores, and safety protection devices. By adopting the latest DSP operation measurement chip control technology, fast AC sampling technology, effective value correction technology, current zero crossing switching technology, and fast compensation voltage stabilization technology, intelligent instruments, fast voltage stabilization, and fault diagnosis are combined to achieve full electronic control, making the product safer, more efficient, and more precise.
Power range: 40KW-1000KW, dual-channel output.
EVR is the modern standard for voltage regulation in most power quality applications
The cost of EVR is about 25% higher than comparable mechanical voltage regulators, but the difference in correction speed often prevents the use of mechanical devices
The output voltage regulation is good (tap-changer) to very good (double conversion)
Ultra-fast voltage correction speed
The number of correction cycles is unlimited
Versatility of KVA rating, voltage and configuration
Very low or no regular maintenance
Good line isolation
The current overload capacity and durability of the EVR can exceed that of the brush type mechanical regulator, because the brush is often damaged quickly when subjected to high currents
Eliminate the inherent overload weakness of FPS and dual conversion units
