QVR-RFI 17A Non-Switched Phase Angle Regulator with RFI Suppression

The QVR-RFI 17A Phase Angle Regulator is a robust and compact variable phase-angle voltage controller designed for precise power regulation of single-phase mains-driven loads. With RFI filtering, it is particularly suited to commercial kitchen equipment, quartz lamps, heat lamps, ovens, restaurants, hospitality equipment, and other demanding applications.

Offering adjustable 0–98% output, the QVR-RFI provides smooth voltage and power control while its high-current TRIAC design helps manage demanding inrush conditions. Available in non-switched, switched, and multi-position potentiometer configurations, it provides flexible installation options for OEM and replacement applications.

⚠️  NOTE: This regulator is a high-current solid-state device. Efficient heat transfer is mandatory for reliable operation. For proper installation, a thermal grease/paste MUST be applied evenly to the back of the regulator before mounting to ensure maximum thermal coupling.

Operation

The QVR-RFI uses phase-angle control to regulate the voltage delivered to the connected load. Rotating the potentiometer adjusts the output from approximately 0 to 98%, allowing the user to control heating power or the operating level of suitable electrical equipment.

The regulator incorporates a high-current TRIAC capable of handling significant surge currents, making it suitable for applications where heating elements or lamps experience high inrush currents during energisation.

The RFI version is designed for applications where radio-frequency interference suppression is important, helping provide cleaner operation in environments containing sensitive electronic equipment.

• Dryers
• Heating elements
• Transformers
• Suitable single-phase motors
• Other compatible inductive loads

Benefits

• Precise variable voltage control
• Adjustable power output up to 98%
• High current-handling capability
• Improved RFI performance
• Compact design for equipment integration
• Flexible potentiometer configurations
• Suitable for commercial kitchen environments
• Reliable solid-state power regulation
• Ideal for OEM equipment and replacement applications

Safety & Installation

• Installation should only be carried out by suitably qualified personnel.
• Isolate the mains supply before installation, adjustment or maintenance.
• Thermal grease/heatsink paste MUST be applied evenly to the rear of the regulator before mounting.
• Effective heat transfer is essential for reliable operation.
• The warranty is void if the required heatsink paste is not used.
• Ensure the regulator is mounted to a suitable heatsink or thermally conductive mounting surface.
• Do not exceed the recommended load for the operating ambient temperature.
• Ensure adequate ventilation around the regulator.
• Select the correct 110V or 230V version for the application.
