Its special benefit is the optimised heat dissipation through the integral water cooling. This foot print resistor enables the customer to assemble his Cold Plate inverter or an other component direct on the resistor and to have his component cooled using the same water-cooling of the braking resistor. The biggest benefit of a liquid cooling is the independence of the ambient temperature in the installation location. With high ambient temperature the resistor may remain cooler than the ambient temperature and thus to a limited extent may also cool down the environment. The water flow temperature for cooling of the components in general is considerably lower than the ambient temperature. The cooling pipes made of aluminium are suitable for most of the standard liquids and oils. The braking resistor is completely wired and with internal aluminium piping.

Overload factor

The ratings apply for continuous duty (100 % duty cycle). In many applications in practice resistors are not being used in continuous operation, they are charged for a short-time only. The ratings may be increased in short-time duty in fuction of the duty cycle by multiplication with the correspoinding overload factor from the diagram below.
