ULC-RFI 17A Switched Regulator – 4 Position, 230V | Quartz Lamp Control
Description
The ULC-RFI 17A Switched Regulator is a high-performance phase-angle power controller with integrated RFI suppression, designed for precise voltage regulation on single-phase 230V loads up to 17A. Serving as a direct replacement for the QLC RFI, this unit is ideal for catering, industrial, and heating applications where smooth dimming, stable power control, and interference protection are essential.
Engineered with a high-capacity TRIAC and robust surge protection, the ULC-RFI ensures dependable performance even under demanding inrush conditions. Its compact, panel-mount design allows easy installation, and optional accessories—including a silver adhesive label and hairline control knob—provide a clean, professional finish.
