Function and use
NW5 series power quality power units are suitable for power systems with AC 50/60Hz and rated voltage AC690V or less. The product integrates multiple core functions of harmonic control, reactive power compensation, and three-phase unbalance control. It can accurately detect and filter out grid harmonics from 2 to 50 times, with a harmonic compensation rate of more than 95%. It can quickly track changes in load reactive power, increase the power factor to more than 0.99, and effectively balance three-phase currents, completely solving the problem of power pollution caused by nonlinear loads.
Detailed description
Parameters:
Rated voltage: 220V/400V/480V/690V
Noise index: ≤65dB
Full response time: ≤10ms
Communication interface: RS485
Advantages/core functions:
01 Flexible adjustment
SVG, APF Both have reactive power compensation, harmonic control, and three-phase unbalance control capabilities. The priority can be set independently, and the management function is more powerful. The compensation function can be flexibly adjusted according to the site conditions
02 The product performance is better
The overall machine efficiency is up to 97.5%, the product performance is better, and the use is more energy-saving. Under full power operation, the annual power loss of a single module can be reduced by up to 4000+kwh
03 Multi-scenario adaptation
A variety of voltage specifications (220~690V) optional; two frequencies (50/60Hz) adaptation, more optional specifications, adaptable to more application scenarios
