Thermostat-Controlled Cabinet Fan Heaters
One box, one job, no extra wiring: the CRH-100W packs a PTC element, a fan and temperature control into a single DIN-rail unit. Power options run from 50W to 500W, so the same family covers a small terminal box and a large outdoor panel. The easiest heater to specify when the customer does not want to source a thermostat separately.
Heating and Temperature Control in One Box
A fan heater and a thermostat usually mean two parts, two DIN-rail slots and two wiring runs. The CRH packs the PTC element, the fan and the temperature control into one unit, so a panel builder installs a single part and is done.
Power spans 50W to 500W, which covers a small terminal box and a large outdoor panel with the same family. The factory-set switch-on is around 10C, adjustable on request, and a thermal fuse plus the PTC self-limiting element give double protection. DIN-rail mount, -40C to +70C operating range.
