BVR-25A-230V | Burst Firing AC Regulator

Description

BVR-25A-230V Burst Firing AC Regulator

The BVR-25A-230V is a robust OEM 25A AC energy regulator designed for precise proportional manual control of single-phase resistive loads. Using burst fire control aligned to mains zero crossover, it delivers clean, RFI-free operation with a full 0–100% output range.

Engineered for industrial and commercial heating applications, the BVR-25 offers adjustable block burst control — from rapid burst firing to a variable duty cycle of 1–30 seconds — giving users accurate and stable heat management.

Key Features

• Integrated high-speed fuse for reliable protection
• Built-in heatsink and mounting plate for efficient heat dissipation
• RFI-free operation using zero-cross burst firing
• Single-entry cable gland for simplified wiring
• Control knob and dial supplied for easy manual adjustment
• Variable duty cycle range: 1–30 seconds (adjustable via trimmer)
• Rapid burst fire mode capability
• Available in 230V AC models
