Space saving high power resistors, studied for all those cases in which a high dissipation power is required, but problems of space or aesthetics do not allow the employment of a classic IP22  resistor system in metal box.


HPR resistors consist of RFH resistive bodies inside an aluminium case, provided with an efficient heat sink and shaped for an easy mounting. These characteristics guarantee the same performances as a traditional resistor bank in a volume up to 5 times smaller, with a high degree of protection (IP55) and full inalterability of surfaces and connections, even in the extreme conditions of a “building site” installation.


Also available on request with external IP20 protection grid and IP23 cable box (HPRG).
