But the bigger issue is that when the bed heater is ON the temperature sensitive is is the biggest issue in that it causes the power supply to cycle way to often and how I know this it is because it hooked up with a UPS device that has a amp bar graphics that pegs the meter range

The plain is put a PWM controller on it and have it stay on longer yes I know that it might make the temperature sensitive to swing a little bit but if adjusted correctly it will probably be okay
