RFH100 – RFH 100
I.R.E
ALUMINIUM HOUSED BRAKING RESISTORS
STUDIED TO DISSIPATE HIGH POWER IN TRANSITORY STATES,
THEY ARE THE IDEAL SOLUTION FOR INVERTERS, SNUBBERS AND
MOTOR BRAKING.
RFH RESISTORS CONSIST OF A HIGH RESISTIVE ALLOY CORE IN A
CERAMIC SUBSTRATE, PROTECTED WITH A VERY THICK CASE OF
EXTRUDED ALUMINIUM, OXYCOLOURED (NEUTRAL STANDARD)
AND DESIGNED TO ALLOW EASY MOUNTING AND HIGH
DISSIPATION.
HIGH QUALITY, STAINLESS, FIRE-PROOF COMPONENTS AND A
SIMPLE AND FUNCTIONAL DESIGN ENSURE A PRICE/PERFORMANCE
RATIO WHICH IS CERTAINLY AMONG THE MOST INFERESTING ON THE MARKET.
