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

Description

Introducing the BVR-25 series, a robust OEM 25A AC energy regulator designed for precise proportional linear manual control of resistive loads. Utilising burst fire control, this advanced regulator delivers variable on/off bursts of complete main cycles of energy, aligned with mains zero crossover. Achieving a full 0 to 100% output range, the BVR-25 allows for block bursts with adjustable block lengths, ranging from rapid burst fire mode to a variable duty cycle of 1 to 30 seconds.
