Background

Hydro Turbine AC POWER SOURCE

Frequency stabilized power supply
DW 1/ 3 1/ 3 5K
DW series Input phase number Output phase number Power5KVA
Product overview:
The DW series stabilized frequency power supply manufactured by our company is specially designed and developed for the unstable power supply voltage and frequency, serious voltage malformations, and comprehensive voltage quality problems such as flicker and drop, to ensure the precision of power equipment with high requirements for power network.
Product Description:
The power supply uses advanced high frequency pulse width modulation (SPWM) IGBT inversion technology. It has an AC-DC circuit design structure and a special power frequency isolation transformer. It is safe and reliable, completely eliminates power grid interference, and the output waveform is pure. It has the characteristics of stable voltage and frequency stabilization with high accuracy, light weight and small size.
