Thermostats and Controllers
The SCC-001-B thermostat works on the basis of a bimetal make contact and does not require its own power supply. Ideally it is connected into the current feed to the power supply unit which supplies the Peltier cooler. In this way the cooler is only turned on if the temperature exceeds an adjustable switching point. Thus overcooling of the switch cabinet with switched off electrical loads can be prevented.
The SCC-002-B hydrostat also does not require its own power supply. It has a changeover relay and is the ideal extension to the PSE-001-B switch cabinet dehumidifier. The SCC-002-B makes it possible to only switch on the dehumidifier when the relative humidity in the switch cabinet is high enough to require a dehumidification.
The SCC-003-A controller is specially designed for controlling Peltier coolers. It has 2 setpoint temperatures and automatically switches the cooler to cooling or heating mode. Thus it is possible to keep a switch cabinet within a specific temperature range, regardless of the outside temperature. The supply-voltage is 24 V-DC, the switching-current is 16 A.
