Features
Using timing control function, the setting is simple and convenient, and the working time of positive and negative current polarity can be arbitrarily set according to the plating process requirements.
It has three working states of automatic cycle commutation, positive and negative, and reverse, and can automatically change the polarity of the output current.
How to install rectifier
This is installation way for remote control rectifier. Not only this way.
1. To connect copper bar with bath/tank
2. To ensure power supply/rectifier is grounded
3. To ensure there is enough water for water cooling type power supply/rectifier
4. We advice that all rectifiers should be isolated to increase of its life.
Other advantages
1. Cabinet
a: Adopting completely digitalized machining
b: Adopting cold rolled production of iron steel sheet, after phosphorization, zinc plating, plastic spray, the rectifier gets better structural strength and anti-corrosion.
c: Reasonable structure design, isolated inverter design, rectification part is convenient to disassemble and mend because of its neat assembling.
d: Radiator gets better cooling effect because of its 1.5 times capacity.
2 Electric control system
a: The rectifier adopts full bridge phase-shifted soft switch control, ensuring the lowest power loss of IGBT. The capacity of IGBT become 3 times bigger.
b: The main transformer. It adopts amorphous core to increase transformer efficiency and cool transformer, and not only can lighten rectifier weight, but also can strengthen rectifier stability and reliability. At its elementary stage, it adopts series blocking capacitor.
c: Magnetic deviation automatic correction circuit is adopted and the total power of magnetic core gets enlarged 1.5 times.
3 Schottky Barrier Diode
a: It has been expanded 4 times.
4 All the controlling boards get antiseptic treatment with imported lacquer.
