Product Details:

A Watlow SCR power controller is a high-power electronic switch that precisely regulates heater power using thyristors instead of mechanical contactors. 

Specification:     

• Type: Solid State Power Controller (SCR / Thyristor-based)
• Function: Controls electrical power to heaters (0–100% regulation)
• Load type: Resistive & infrared heating elements
• Phases: Single-phase / 2-phase / 3-phase models
• Current range: ~65 A to 1000+ A (model dependent)
• Control modes:
  • Phase angle firing
  • Zero-cross / burst firing
• Accuracy: High stability (±2% typical control linearity in modern models)
• Communication: Modbus RTU/TCP, EtherNet/IP (advanced models)
• Protection: Short circuit / SCR fault / heater break diagnostics (model dependent)
• Cooling: Air-cooled or fan-assisted (higher amps)
• Mounting: Panel / DIN / modular rack systems
• Input control: PID controller (4–20 mA, logic, or digital commands).
