Housed Metal Clad Braking Resistors
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.

ORDERING PROCESS
FOR EXAMPLE:-
ONICS
UHPAR1KW100RKTW3MM/YY
ONICS – BRAND NAME
UHPAR1KW–MODELNUMBER
100R = RESISTANCE VALUE,
K=TOLERANCE10%,T=THERMALSWITCH,W3=WIRETERMINAL300MM 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.
