FCP Speed Controller
FCP Speed Controllers
Speed Controllers For Stand-Alone Condensing Units
FCP is a speed controller for single-pahse fans on stand-alone units with up to two circuits.
It controls the fan speed according to the variation in pressure in the condenser circuit, so as to maintain the set point, via a 0 to 5 V signal from the ratiometric pressure transducer (SPKT*R0) positioned in the water circuit.
This device is installed directly on the condensing unit. It can control asynchronous electric motors (specific for phase control), with a load of up to 8 A / 230 Vac.
Available in the Master/Slave or power version.
