Power wire resistor family PWR-TR 4xx up to 2600 W
Resistance wires material of NiCr alloys have a high thermal capacity and are well suitable for continuous power and pulse loads. Oxidized wire is used for the very powerful series of PWR-TR4xx. The oxide layer takes over the insulation between the coils and so can be omitted on the usual cement. This thermally optimised resistor designs a lot of possibilities to combine resistance values and performances. Specially selected materials guarantee a maximum of reliability and stability. The PWR-TR4xx series can be completed with different terminals and mounting accessories. On request, we can realize other kinds of terminals or mounting options.
For special requirements with high security we offer a resistor with fuse. A spring clip opens if a critical surface temperature is reached.
