"VPN-650" power rectifier is made as a thyristor rectifier circuit and is intended to power plasma deposition plants. The thyristor rectifier, power transformer and inductor are water-cooled.
Structurally, the control system is a cassette with a set of modules implemented on a modern element base.
The source control system provides regulation of the rectifier output current.
Advantages of the VPN-650 source:
- fast shutdown in cases of current overload;
- easy of maintenance;
- no phasing required for source when first turned on;
- easy pairing with central control devices.
