IGBT Pulse rectifiers for silver plating with 12v 100a 220v AC input
features:
Normal silver electroplating machine can’t obtain bright plating coating directly, in order to get brightness need chemical dip or barrel rolling treatment, but will cause silver electroplating coating loss, and difficult to recover 50% of loss, resulting in a greater waste. Bright silver plating can obtain bright plating coating directly, which simplifies operation and reduces waste, but electro plating coating antitarnishing worse, and conductivity deteriorates. Because silver in the air due to the sulfur can easily change color, additives, mostly as sulfur compounds, attached to plating coating inevitably promote its easier to change color, thereby seriously affecting the electrical plating and welding properties. Furthermore, the plating agent attached (in this case the agent can be regarded as impurities) make the silver plating layer impure, electrical properties then decrease. To make an inappropriate analogy, cold medicine to cure a cold, but comes with side effects (such as dizziness, drowsiness, etc.). Bright silver palting solution additives like cold medicine, the use of which may obtain directly bright silver plating layer, but side effects (such as anti-tarnish coating capacity, electrical conductivity variation, additive decomposition products difficult to handle, etc.)

IGBT Pulse rectifiers for silver plating with 12v 100a 220v AC input cooling method:
- High frequency switching power supply AC to DC rectifier adopts air cooling/water cooling design, easy to install. With remote control device, simple operation. Can switch off the machine when loading, reduce cumbersome procedures of adjustment.advantage of small size and energy saving:
- Small size, light weight, the whole high frequency water cooled zinc plating igbt power supply 18v 3000a machine use a full range of anti-corrosion technology, enhanced the product’s anti corrosion ability, extend the service life.
- High efficiency, energy saving, work efficiency can reach more than 90%, any voltage current ratio is always linear matching. Eliminating the need for traditional rectifiers regulator and the main transformer loss, energy saving in more than 35%, greatly reducing the electro plating cost, which is the most sensible choice for surface treatment plating machine industry

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.
