EN7000 Constant Current AC Controls with Advanced Features

EN7000v2 is the next generation of our SINGLE PHASE AC / 3 PHASE DC Constant Current Control for 50/60 Hz welding applications. The EN7000v2 can be configured to suit your Resistance Spot, Projection, Seam, Crosswire, Hot staking and Heating applications and can be used with a range of thyristor contactors. To reduce capital equipment costs, the EN7000v2 can be configured as Multi-welder (Cascade) control firing up-to 8 AC welding transformers in a flexible sequence. The EN7000v2 comes in 2 formats, with or with-out integrated touch screen programmer. Both formats included include Discreet IO and integrated EIP.

Please refer to the EN7000v2 & EN7000v2-TS Bulletin.
