EVR-1kW 230V Mini Stack Phase-Angle Power Controller with Soft-Start

The EVR-1kW-230V Mini Stack Power Controller is a compact, high-performance phase-angle regulator engineered for precise proportional control of electrical power in single-phase 230V applications. Designed for smooth and accurate load management, this 1kW controller is built with an integrated high-speed semiconductor fuse, a convection-cooled heatsink and multiple signal-control options, making it ideal for industrial heating and process-control environments.

Offering exceptional reliability, soft-start functionality and flexible installation configurations, the EVR-1kW delivers stable performance across a wide variety of resistive and inductive loads.

Key Features

• Wide range of control signal options including manual, voltage or current input.

• Convection-cooled heatsink for efficient thermal management.

• Phase-angle control with soft-start (0–20 seconds) for smooth load protection and extended component life.

• Integrated SCR-type high-speed semiconductor fuse for enhanced circuit protection.

• Versatile installation options: metal enclosure, DIN-rail mounting with Perspex cover or back-plate mounting.

• Rugged industrial construction with full isolation and overvoltage protection.

• Precise proportional power regulation, suitable for demanding heating and process applications.

Applications

The EVR-Series Phase-Angle Controllers are suitable for precise energy management in a wide range of industrial processes, including:

• Industrial and process heaters

• Ovens, dryers and furnaces

• Air curtains and hot plates

• Ventilation and HVAC systems

• Electroplating and chemical process control

• Controlled rectifiers and transformer regulation

This makes the EVR-1kW ideal for manufacturing facilities, catering environments, laboratory settings and temperature-critical applications.
