1. Switch Mode Rectifiers for Plating Introduction
Switch mode rectifier for plating is a series of switch mode rectifiers designed to meet all surface treatment requirementsof metals and plastics. As a technology specialist in power supplies, Green Power provides wide range of power solutions for various electroplating process, including for nickel plating, copper plating, zinc plating, gold plating, silver plating, chrome plating, hard chrome plating, tin plating, cadmium plating. Based on high speed IGBT PWM technology, Green Power IGBT plating rectifiers provides high efficiency and performance with module structure with compact size, meeting all process requirements and guarantee the user excellent results.
2. We have the best power supply for your electroplating application
Electroplating rectifiers provide reliable and stable DC power supply for various electroplating process covering metal plating and plastic plating, plating on brass, bronze, steel etc., used for barrel plating, rack plating and continuous plating line. Typical types including igbt plating rectifier 1000A 15V, plating rectifier 2000A 12V, copper plating rectifier 1500A 12V, current rectifiers for plating 3000A 12V, gold plating rectifier 500A 12V, ac to dc rectifier 5000A 12V, used plating rectifiers 300A, 100A 12V etc. power supplies.
3. Why Green Power's switch mode power supplies could replace SCR rectifier?
The main advantages of Green Power pulse IGBT plating rectifiers over thyristor rectifiers(SCR) include but not limited to:
● High conversion efficiency, power saving at least 17% than SCR rectifier. E.g for 1000A 12V plating rectifier, suppose 6300 hours running time one year, saving power 18,613kwh than SCR rectifier.
IGBT rectifier adopts AC-DC-AC-DC topology, 3 phase AC is firstly converted to DC, which has capacitors for energy charging and discharging, it will suppress power fluctuation, so rectifiers don't need bigger capacity than actual use.
SCR rectifier doesn't have energy buffer function, it is affected directly by the grid power fluctuation, so it always keeps much extra capacity and increase user's investment cost.
● Pulse output needs less plating time, customer feedback 40% shorter time needed for plating
Rectifier won't break down: in case of one module failure, the rectifier continues working with reduced power
Less downtime and easy recovering: plug-in structure, replacing module directly, downtime is shorten to minimum, this reduces potential high cost of your plant stop and increase your plant's availability and productivity.
Current expansion available: thanks for the modular design and supporting parallel connection, if you need more power, you only need to add more modules.
Less floor space occupied: the rectifiers can be built on top of each other(rack mounted), making them easy to fit into your plant's design, optimizing floor space.
Easy to install and maintain: each rectifier consists of up to ten modules and naturally two or more stacks can be connected to allow higher currents (up to 40kA) and voltages (up to 200V DC).
Separate output or parallel running output available: you can let the rectifier modules with separate outputs to be connected to more tanks, or in parallel connecting to get higher current for one tank.
● Compact size, modular structure, e.g. air cooling 1000A 12V size only 525*600*310mm, weight is only 58kg. much less size and weight than SCR rectifier, don't need forklift
|1000A 12V air cooling||2000A 12V air cooling|
● Low pollution to grid, power factor>0.94
● Lower cost for the same specification
