I am looking at heating a composting toilet in my caravan by building a special base plate to accommodate two of your 100x50 heat pads wired in series. The power supply is 13.6 volts. So I have two questions:
On my rough sums they should reach around 63 degrees. Does that sound about right?
What is the insulation material on the supply wiring that comes with the pads? Will I have to replace it with high temperature wiring?
I assume you mean PWM? Dimmer switchers are normally thyristors - they’ll only work with AC, and most of them are mains voltage. This heating pad is intended for very low DC voltage, though you could equally power it with very low voltage AC - it’s just a bit tricky to obtain that.
