- Wave types are available for direct current method, pulse method, PR method, alternative current method, alternative & direct current method, recovery method, inversion method.
- Nowadays the electroplating rectifier in the market is mainly by direct current method, the global biggest quantity consumed market is in China and it is divided by two categories: high frequency and SCR, these two categories is with advantage, defect individually.
- Advantage of high frequency rectifier: electricity saving, less space occupied, light weight, saving of material consumption, it is mainly used for electronics components application, with more cheaper price. Wave is better than SCR when it is without added wave filter. Defect: most of electronics components is easy to corrode by humidity and acid, alkaline air, trouble chance is higher than SCR type, with less durability, especially is high power capacity. High-frequency rectifier If maker technology is not matured enough,would often malfunction.
- SCR rectifier：Advantage：Low trouble chance, durable long life, with more higher material cost, Electronics components application is less than high frequency type, it is not easy to corrode by humidity, acid, alkaline air. (defect: with more higher price,with more bigger space occupied, with more heavy weight, with more higher power consumption when it is compared with same power of high frequency type).
- Cooling method of high frequency rectifier is available for 2 types: fan cooled type, water circulation cooled type.
- Cooling method of SCR rectifier is available for 4 types: air cooled type, fan cooled type, oil dipping cooled type, oil dipping + water circulation cooled type.
- Air cooled type, fan cooled type, is easy to corrode, aged by acid, alkaline air, due to contacted mechanical components directly, it is not suitable for application when factory site is under higher acid, alkaline air status. Water cooled type , Suitable for moderately acidic and alkaline, air pollution state electroplating factory use.
- Oil dipping cooled type and oil dipping + water circulation cooled type is to immerse most of rectifier unit into oil, mechanical components is not easy to get trouble, due to it is not contact acid, alkaline air easily. It is suitable for application of electroplating factory when it is under higher acid, alkaline air status.
- High-frequency rectifier: High efficiency, very low power consumption, small size, machine light, the price is cheaper than SCR quoqua, becomes the mainstream in China electroplating factory.
- If you can accept expensive, low-failure, durable, oil-immersed SCR rectifiers, it average service life is about 15 years.

- Plating rectifiers are divided into: single-phase half-wave, single-phase middle out, single-phase bridge, three-phase half-wave,three-phase bridge, double star six-phase, and other rectification methods, feasible automatic constant voltage, automatic constant voltage setting Current, automatic current density, etc.
- Plating rectifier series, the current waveform varies due to rectification, DC waveform differences effect the plating luster, current level of uniformity.
- Our company Rectifier has perfect error protection: Such as short circuit, over voltage, under voltage, lack of phase, super fluid,overheating protection etc.
- High-frequency water-cooled / air-cooled rectifiers are divided into / A / B / C / D grades, using different materials, quality and price differences, the warranty period is different. (Electroplating Rectifier consultation, please specify specifications or other
- requirements, etc..).
- When you purchasing any product, it definitely should be supplied by a professional manufacturer and not to pursue cheap price only, easy to use with low trouble is cheap, difficult to use with high trouble chance is expensive.
※Wave Filter:- Can improves the difference of high-low current plating layer (A-grade ripple efficiency is 1-3%), (B-grade ripple efficiency is 4-6%), (C-grade ripple efficiency is 8-10%), ( D-grade without ripple function), (Chrome-Plated advisable add ripple filters).
- (The ripple more fine is more good coated for low electric are plating layer, also the machine will be expensive), (Because of the market competition, in addition to the customer inquiry the ripple power needs to reach up how much %), general suppliers is not free-will to tell to add the ripple filter)
- Waveform of rectifier plays affect hugely to electroplating quality, the rectifier, ripple, and shunt as necessary accessories in Europe, the U.S.A., Japan
There are available for added optional accessories, the unit price will be surcharge as below.
- Ampere Meter: accumulates amperage record for supplying parameter reference in consumption and refill electroplating additive.
- Slow start : to avoid sudden pressure raising and causes electroplated parts with corner burnt due to high current.Generally it is apply for plating decoration chrome and Electrophoretic paint treatment.
- Pre-dip dimension setting start electrification : reduces surface of plated parts with air bubble holes, generally is apply for electrophoretic paint treatment.
- Setting of multi-step automatic timing pressure raising : reduces personnel operation fault by carelessness, generally it is apply for aluminum anodizing.
- Positive /Negative pole switch. To install on the rectifier to operate control anti-electrolysis degreasing etching, activate, electroplating, adds the adhesion of electroplating layers. Generally it is most suitable for apply for iron-steel material of hard chrome plated.
- Digital type of timing meter, alarm, to remind the operator for plating time.
- (Inquire about the product please specify: DC：V and A specifications and other related requirements, etc.)
- (Including AC:220 / 380 / 415 / 440 / V ±10V /single-phase/three-phase 50 / 60HZ )
