The 4003 series power controllers are compactly packaged to allow for fast and easy DIN-rail or sub-panel mounting, with wiring terminals easily accessible from the front. The depth and height of all controllers in the 4003 series are consistent, optimizing the mounting and wiring of mixed controller types. Optional heatsink thermostat protects the SCRs from failure.

Quick, Easy Installation
The 4003 series power controllers are compactly packaged to allow for fast and easy DIN-rail or sub-panel mounting, with wiring terminals easily accessible from the front.

Electrical and Safety Features
• Ground Potential Heatsink
• SCR to Heatsink Isolation
• SCR resistant to Electrical Spikes, PIV up to 1600V

Minimal Electrical Noise
The dependable back to back SCRs fire at the zero-crossover (zero voltage) point in the sine wave. This minimizes both RFI and EMI that can create havoc for other electronic equipment in a plant.
