VIRDI'S Electroplating Rectifier is an economical and most efficient method of obtaining D.C. from A.C. supply by anodizing and many other electrochemical processes. The widest applications in the field of electroplating normally require the maximum voltage of 8V, 12V, 16V and 20V D.C. at various current capacities as per requirement. A range of current rating from 50 to 5000 amps is covered in our regular range.(Other ranges available on specific order)
VERDI'S RECTIFIER FOR RECTIFIER FOR:
- Cleaning Other Electrochemical Processes
VERDI'S Rectifier is designed for three phase 50 Hz A.C. input supply are suitable for operation at any voltage between 380/415 volts bread crumbs needs to be corrected
The D.C. output is variable in steps or continuously and stemless variable from Zero to its rated full load. VERDI'S rectifier comprises of the following controls for D.C. output:
VER-15 Steps Control (range variation from 40% to 100% D.C. output voltage).
VER-63 Steps Control (range variation from 15% to 100% D.C. output voltage).
VER-Stepless Control (range variation from 0% to 100% D.C. output voltage).
VER (S)- (Stepless control with a transformer in the separate tank).
The ripple content in the output is very low and is less than 5% and as such these units are very much suitable for all special processes such as chrome plating where low ripple content is necessary.
The circuit employed in VERDI'S Rectifier is simple and universal. A.C. supply is given to an auto-transformer, which in turn supplies a variable voltage to the primary of a three phase double would Delta/Double star connected transformer. The secondary of the transformer is connected to hex a Phase/ Bridge connected rectified using silicon diodes. The output is obtained from the rectifier and the star points of the transformer through an interphase transformer.
This is made up of sturdy liberally rated silicon diodes are connected in parallel. On a special made up of casting heat sink and depending upon the output rating of the rectifier units.
A moving coil ammeter and a moving iron voltmeter along with indication lamps are provided on a panel indicating the output current. The panel is mounted on one of the tanks to enable easy manipulation.
