SRP SCR DC Power Supply

SRP is three-phase input high-power DC power supply adopts SCR rectifying technology, which could give high power DC output (up to 1000KW), which linear mode and switching mode could not reach.



And different from common DC rectifiers, this series has perfect built-in filtering circuit to give stable & precise high power DC output.



Also this series has perfect protection functions which give safe operation; currently it is widely used for high precision electroplating, corrosion, energizing, accumulator manufacturing and electrolysis etc.
