Speed controller RDCPSD

RDCPS(KB0) series D type controller,is mainly applied to power system of AC50Hz,rated operational voltage up to 400V,rated current from 1A to 125A,control motor power from 0.05kW up to 50kW,to realize the speed control and protection against overload,phase-loss,overcurrent,short-circuit for double-speed motor. Normal operation condition 3.1 Amibent temperature:MAX +40C,MIN -5C.Average dairy temperature:+35C 3.2 Altitude:2000m 3.3.Humidity:Max50% at +40C.the higher humidity can be accepted under the lower temperature,like Max90% at +20C.And the condansation caused by temperature change should be taken care. 3.4 Pollution level:3 level 3.5 Installation type:install type is related with rated operational voltage,Install type of Main circuit under 380V is IV,Install type of Main circuit and control circuit under 690V is IV,alarm circuit installation is II. 3.6 Install method:Angle between Install plane and vertical plane should not exceed 5. 3.7 Install type:install bottom board with 4XM6 screw.
