RELAY MODULE 240V for Blichmann Power Controller

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 doesn’t create electrical noise like other techniques can.  See below for other great features.
