Three-Phase Thyristor Power Regulator
- 32-bit high-performance control with precise voltage and current regulation.
- Robust electrical isolation enhances safety and interference immunity.
- RS485 Modbus RTU support for remote monitoring and control.
- Compact design for easy installation in control cabinets.
- Features protection against overcurrent, overheating, phase loss, and load disconnection.
Product Overview & Applications:
How to select products?
Actual current per phase
Power (W) ÷ 380 ÷ √3
For example: Actual current for a 50kW resistive heater
50000 ÷ 380 ÷ 1.732 ≈ 76A
The built‑in thyristor module in the power regulator already amplifies the normal margin. Choose one around 100A.
There’s no such thing as a 2x, 3x, or 5x margin.
