Closed-Loop Three Phase Thyristor Power Regulator 25A-200A Get latest price

Overview

This Lorentzzi three-phase power regulator is intended for applications where basic open-loop power control is not sufficient. Closed-loop regulation can help maintain a selected electrical parameter despite supply or load variation, making the product suitable for demanding process-heating and power-control applications.

Key features

• Current ratings listed from 25 A to 200 A
• Closed-loop constant-voltage, constant-current and constant-power modes
• Open-loop operating mode also available
• 4-20 mA and 0-10 VDC analog control options
• Potentiometer control option
• RS485 communication
• Soft-start function
• Designed primarily for precise heater power control
• Can also be used with a transformer for indirect heater control where suitable
  
  

Applications of this product

• Precision industrial heating systems
• Ovens and furnaces
• High-value process temperature control
• Heating loads affected by supply-voltage variation
• PLC/HMI or network-integrated power-control systems
  
  

Why choose this product

• Closed-loop modes provide more controlled power delivery than a basic SCR regulator
• RS485 enables integration with PLC/HMI and supervisory systems
• Multiple current ratings cover a broad range of industrial heaters
• APS can integrate the regulator with sensors, PID/PLC/HMI and control-panel hardware
