Memco P.W.M Chopper Series Welding Rectifier

Features :

Chopper 400/500/600

Sturdy and proven construction to withstand extraordinary welding environments
Rugged construction for long life and least maintenance
Very high power factor
Stepless current regulator over the entire range
Constant current characteristic regardless of + 10% or - 15% voltage fluctuation
Fully protected against single phasing and short-circuiting
Thermally protected against overload, under voltage and abnormal supply or site condition
Specially designed for insensitivity to voltage transience due to galvanic separation from the mains
Intelligent fit-up of active component on the low voltage side makes the PWM chopper series more reliable, resulting in faster control and better welding
