Another question from a customer that, I thought, could be useful for some people:
Do you market a temperature controller with a proportional output at mains voltages capable of handling 5 amps?
We require the current to be continuous, varying only to adjust the temperature. It is for an air heater with a low thermal mass so we require continuous proportional control, a simple on/off type (relay
output) would be clicking away all the time with consequent fluctuations in air temperature.
