SCR rectifier compare HF power supply

SCR rectifier compare HF power supply

,

In the plating industry application, normally, there are two types of rectifier, which is:

1, Silicon controlled rectifier.
2, High frequency power supply.
While, what is the different between for the 2, sometimes it will cause us confused to choose them.
Here we use a table sheet to find out what exactly difference for them.

For easy to distinguish, we choose same power: 1000A 12V type rectifier. From this, I think you will know which one is what you want.

Electroplating rectifier application in hard chrome plating

Hard chrome plating high frequency electroplating rectifier absorb new technology, adopting international standards do 15KHz frequency pulse as signal source, and high-power IGBT soft-switching resonant converter technology, which are both in the international and domestic leading technology and unique applications constant current technology, constant current control accuracy up to 1 ‰, industry-leading, high-frequency, high-power, pulse width (big working rate) output, the cost performance is much better than similar products. Electroplating rectifier application in hard chrome metal plating case, and can be set two, three level strick hard chrome work method, so the chromium layer uniformity, strong adhesion, and can increase the thickness, showing additional advantage of energy-saving (90% efficiency), save time (takes only two-thirds of original electroplating rectifier, or even shorter), material-saving (raw material can save 30%), high efficiency (each working section can increase capacity of more than one-third).

Three phase electroplating rectifier features:

1. Electroplating rectifier machine adopts antiseptic treatment, sealed control components, each adapter sealed plastics, in order to protect them air corrosion from acid, alkali and salt, to ensure long-term stability working in corrosive environments.
2. Leading international technology, to achieve real high current, high frequency, high working rate pulse output.
3. PVC shell or spray metal shell, beautiful, will not corrode, straight cooling structure, installation and maintenance is very easy.
4. High efficiency (≥90%), a significant electricity saving (saving more than 30%) (6V1500A electroplating rectifier compare with silicon rectifier and SCR, can save electric charge more than $1600/year).
5. Variety control of constant voltage, constant current, steady current, constant power, etc.
6. Current, voltage, working time, frequency meter (optional), return meter (optional) and other all use high precision digital display, with sound and light alarm.
7. Soft start and stop function, with over current, over voltage, less voltage, over temperature, phase loss, less water, and short circuit protection function, high reliability.
8. Before delivery, our electroplating rectifier through rigorous testing and long time aging test, can be at full load day and night, uninterrupted running under high current, the failure rate is very low.
9. Adopting our electroplating rectifier, the plating layer can be more uniform, dense, good finish, enhanced the plated workpieces wear resistance.
10. Short working time, high efficiency, saving raw materials, reduce cost, will help you increase output efficiency multiplied.
11. Small size, light weight, easy delivery.
