GMS20CA Single Phase SCR Controller

The GMS20CA is a single-phase constant voltage, constant current, constant power of power regulator with a highly integrated feedback control voltage stabilization system. It is suitable for various industrial and commercial applications. 

Product Features

🔸 Multi-Function Switching

Supports three modes: constant voltage, constant current, and constant power.

Easy switching via a digital panel or third-party communication devices (e.g., RS485 bus) by setting parameters.

🔸 Highly Integrated Design

Built-in high-power thyristor chip with digital phase-shifting control circuit.

Integrated output voltage and current measurement circuits.

Built-in MODBUS-RTU communication system based on the RS485 bus for remote control and monitoring.

🔸 Communication and Control

Supports 0-10V or 4-20mA control signals, with settings adjustable via the digital panel.

Provides two sampling methods: average value and RMS (root mean square), which can be configured as needed.

Features overvoltage and overcurrent protection, with overheat protection triggered when the temperature exceeds 80°C.

🔸 Intelligent Monitoring

Supports open-circuit detection and lifespan monitoring for lamps.

Automatically detects the absence of AC input.

🔸 Convenient Operation and Maintenance

Equipped with an operable digital panel for easy parameter viewing and modification.

Adopts pluggable control terminals with spring-press wiring, making it convenient for troubleshooting and device replacement.

🔸 Integrated Design

The controller and heat sink are integrated into one unit, eliminating the need for an additional heat sink.

Unique installation structure supports both rail and screw mounting.

Operating Environment Requirements:

🔸 Operating Temperature: -25°C to 45°C.

🔸 Environmental Conditions: The surrounding area must be dry, ventilated, away from heat sources, and free of dust, corrosive liquids, and gases.

Safety Precautions

🔸 The controller cannot be used as an isolation switch.

🔸 To ensure safety, an air switch must be installed in front of the controller.

The MS20CA is designed with high performance, ease of operation, and safety in mind, making it suitable for scenarios requiring precise power control, such as industrial heating and lighting control.
