Aluminium Housed Power Resistors
Type CFH Series
Type CFH Series
The CFH is a high quality range of
aluminium housed power resistors
offering environmental protection to
IP55, 6kV dielectric strength,
1.8kW power dissipation, and the
ability to absorb electrical pulses of
up to 24kJ.
The use of advanced materials in
the construction of this device
enables operating temperatures of
up to 450ºC giving very high power
density.

Heat Dissipation:
Although the use of proprietary heat sinks with lower thermal
resistance is acceptable, up rating is not recommended.
The use of proprietary heat sink compound to improve
thermal conductivity is essential.
