Product description
The Deltasol AL E HE is equipped with a PWM output and two strong-current relays to which an electric immersion heater up to 3 kW (230 V~) can be connected. The heater can be connected directly to the controller without the need for additional relays. For data communication, the controller has a RESOL VBus.
