For use with the Blichmann 240V Electric Brewing Power Controller. Add up to 4 additional relay modules and drive them all with one power controller. Unlike cheap “dimmer switch” based power controllers, whose power output is not linear, the modular power controller is much easier to control the perfect boil intensity and heating rate. We accomplish this using a tried and true industrial technique called Pulse Width Modulation (PWM). Simply put, it controls the percentage of time the heater is energized over a very short 1 sec interval. So turning the knob to 6 energizes the heater for 0.6 seconds, and turns it off for the remainder of the 1 sec interval. This robust reliable technique is gentle on your heater, is extremely linear, and doesnt create electrical noise like other techniques can.
