High Power Aluminium Resistors (UHPAR)

Onics UHPAR series resistor are capable of withstanding very high pulse loads, at the same time they get cooled faster compared to conventional resistors and are best suitable for wind turbines and other braking applications. These resistors are available in eleven different power ratings. These resistors are continuously rated.

For Example:-

Onics

Uhpar 1kw 100R K T W3 mm/Yy

Onics – Brand Name

Uhpar1kw – model number

100R = Resistance Value,

K=tolerance 10%,T=thermal switch,W3=wire terminal300mm Length, Mm/Yy = Month/Year of Manufacturing

Note: -

For 5% tolerance use J instead of K.
For 500mm wire terminal length use W5 instead of W3.
For clip terminal use C instead of W3 or W5.
