Dear Sir,

We are pleased to introduce our W7 Series Digital SCR (Thyristor) Power Regulator (Controller), designed specifically for high-performance heater and temperature control applications.

Engineered with cutting-edge digital technology, the W7 Series offers exceptional precision, versatility, and energy efficiency—helping you reduce operational costs while enhancing control reliability. We are confident this solution will be an ideal fit for your thermal control needs.

Key Features of the W7 Series:

• Fully Digital Control with high resolution and accuracy
• Wide Input Voltage Range: 40–120VAC, 180–480VAC, 460–690VAC
• High Capacity: Single unit supports up to 750A
• Versatile Control Modes:
• Phase Control (Proportional)
• Zero-Crossing Cycle Sampling (Variable Cycle)
• Zero-Crossing Time Sampling (Constant Cycle)
• Phase Start → Zero-Crossing Sampling
• Constant RMS: Voltage / Current / Power
• Current Limiting
• Flexible Control Inputs:
• Analog: 4–20mA, 0–20mA, 1–5VDC, 2–10VDC, 0–5VDC, 0–10VDC
• Digital: RS-485, Keypad input
• Supports Various Load Types:
• Resistive Load
• Inductive Load (e.g., Transformer)
• Infrared Lamps
• MOSi₂ Heaters
• Complex Resistive Loads
• Removable Front Panel Keypad:
• Functions as an independent programmer or display unit
