Danotherm, 68Ω 75W Wire Wound Chassis Mount Resistor CAH165C777-68R-KT ±10%

These dynamic braking resistors are insulated and can easily be mounted in compact constructions. They are specially constructed for high pulse loads compared to the average load. The nominal load can be improved by forced air cooling or by mounting the resistors on a heat sink.

Compact size

The CAH series is a range of braking resistors from Danotherm's medium power range of Alpha aluminium housed compact resistors. They are electrically insulated and feature small dimensions. They can easily be fitted into compact constructions and are especially designed to endure high pulse loads in industrial drive systems. The steady state power range spans from 70 W to 410 W per housing. The pulse load capability is up to 75 times the nominal power for one second every 120 seconds, and 18 times the nominal power for five seconds every 120 seconds, depending on the ohm value and resistor type. Danotherm has developed thermal models for all resistor types and resistor values. By using these models, they are able to predict the temperature rises of the resistor wire and on the surface for all possible load applications.
