TND series voltage regulator is a common type voltage regulator power supply, this series of voltage regulator varieties, specifications, beautiful appearance, economic and practical advantages. It has the characteristics of small size, light weight, undistorted output waveform, high efficiency, stable performance, reliable, simple maintenance, long-term unattended operation, and has the protection function of short delay start, overvoltage/undervoltage
Power range: 40KW-1000KW, dual-channel output.
Can be made into high-power compensation power supply TNS
Three-phase AC power regulator, is designed for stable AC voltage
Easy to produce, low cost, cheap
Good adaptability to load properties
The whole machine efficiency is high (auto-regulator loss is small, the general efficiency is more than 95%)
The output voltage waveform is the same as the input voltage waveform, and the phase is also consistent
