Thyristor controller panel

Thyristor Controlled Panel

A Thyristor Controlled Panel is a precision-engineered power control system that uses thyristors (SCRs – Silicon Controlled Rectifiers) to regulate and manage the flow of electrical energy to resistive or inductive loads. At Swaraj Engineers, we design and manufacture high-performance thyristor panels that offer seamless power regulation, energy efficiency, and reliable operation for critical heating, lighting, and motor control applications.

What is a Thyristor Controlled Panel?

A Thyristor Controlled Panel provides solid-state switching to control power supplied to electric loads. It replaces traditional electromechanical contactors and relays, offering fast, silent, and wear-free operation. These panels are ideal for applications where precise and continuous control of electrical power is essential, such as in industrial ovens, furnaces, heating systems, lighting banks, and variable voltage systems.

Key Features:

  • Solid-State Switching: Uses SCR modules for smooth, contactless switching with long operational life and minimal maintenance.

  • Precise Power Regulation: Offers phase-angle or zero-cross control for accurate output voltage and power regulation.

  • Closed-Loop Control: Compatible with PID controllers, PLCs, or analog signals (4-20 mA / 0-10 V) for dynamic control based on temperature, voltage, or current.

  • Modular Design: Scalable and configurable for single-phase or three-phase systems, suitable for small to large loads.

  • Built-In Protections: Includes protection against over-voltage, over-current, short circuit, phase failure, and overheating.

  • User-Friendly Interface: Front panel indicators, digital displays, and optional HMI/SCADA integration for monitoring and control.

Frequently Asked Questions (FAQs)

1. What is a Thyristor Controlled Panel?

A Thyristor Controlled Panel uses SCRs (Silicon Controlled Rectifiers) to regulate electrical power precisely. It provides solid-state switching without mechanical contacts, making it ideal for high-precision control in heating, lighting, and motor-based applications.

2. How is it different from traditional contactor-based panels?

Unlike electromechanical systems, thyristor panels switch power silently and rapidly, without arcing or mechanical wear. This ensures longer life, faster response, and more accurate control.

3. What types of loads can thyristor panels handle?

They are suitable for both resistive (heaters, ovens, lighting) and inductive (motors, transformers) loads across various industrial sectors.

4. What control inputs do you support?

Our panels accept analog signals like 4–20 mA, 0–10 V, and digital inputs such as RS485. They’re compatible with PLCs, PID controllers, and SCADA systems for closed-loop control.

5. What safety features are included in the panel?

Our thyristor panels are built with multiple protections:

  • Over-voltage and over-current

  • Short-circuit

  • Phase failure

  • Thermal (overheating) protection

6. What are the available configurations?

We offer both single-phase and three-phase configurations with load capacities ranging from 10 kW to 1000+ kW, customized as per your requirements.
