Product description
The microprocessor-controlled controller ST501-KU3KA.12P consists of a service and a separate power
pack plate and is used for thermostatic temperature regulation in simple refrigerating plants. It is supplied
with 230V AC and has four relay outputs as well as an exit for a DC voltage fan.
The relays can be used for different functions, e.g. for a compressor, a defroster, an alarm relay, etc.. (see
parameters U1-U4). The two resistance sensors seize the refrigerating chamber temperature and the
evaporator temperature.
