PCG

PCG resistors are constructed with one or more steel tube resistor elements and welded into a frame. The resistive element is an active wire that resides inside the steel tube. The tube is made from AISI 304 stainless steel and is filled with magnesium oxide, which has excellent electrical and thermal properties. The connection box is made of aluminum.

Nominal power ratings for Danotherm PCG resistors range from 1 to 6 kW, and the working voltages are up to 1000 VAC / 1400 VDC. PCG resistors can handle 10 times the nominal power ratings of a 5s pulse with a cycle time of 120s. Resistor cooling is accomplished by natural convection.

A thermal switch is provided as a standard feature. Also, a protection grid to prevent touching the very hot tube elements is standard.

Danotherm PCG resistors are IP65 rated and are suited to harsh industrial environments. They are used as braking resistors for applications with extended braking times and short cycle times. PCG resistors are widely used in elevators, cranes, and other lifting applications.
