The BVR-25 series is a powerful OEM 25A ac energy regulator for proportional linear manual control of resistive loads using
burst fire control – this is principally variable on/off bursts of complete main cycles of energy, coincident with mains zero
crossover. A 50% on/off setting with a light bulb as a load would show even on/off flashes. The output is in block bursts, with
a full 0 to 100% range. The output block lengths can be varied from a rapid burst fire mode to a variable duty cycle range of 1-
30 seconds.
The unit comprises of a high current triac (power device) mounted on an integral heatsink controlled by a populated PCB with
fuse and connection terminals, all enclosed, for simple connection, maintenance and installation.
APPLICATIONS
Virtually all resistance heaters including ovens, electric furnaces, moulders, dryers, smelters, heating tapes, stress relieving,
space heating and heating mantles. Not suitable for use on lighting and inductive loads.
