Description
The BERCO brand (British Electric Resistance Company) was founded in 1926, and since 1976 it has belonged to a British manufacturer of stabilizers and transformers. Bercostat rheostats come in 7 sizes of 25–500 W, with manual or motor drives, in single or tandem versions, open or enclosed. Berco RA resistors are fixed and adjustable, of 20–380 W, with a resistance from 0.22 ohm to 100 kohm, and are made enamelled, in silicone or open. Mica card resistors have 45–260 W. “J” Coil spiral resistors cover 0.1–5.08 ohm and stand on porcelain insulators, which keeps the wire in a heated state without deformation. Tubular ones, fixed and slider-type, give 240–1080 W at 0.2 ohm – 1.4 kohm. The wirewound construction removes heat well, so such elements are taken where currents are significant and smooth regulation is needed, for example in equipment tests, load banks and starting circuits.
How to choose
First the resistance and power are determined, since the ranges of the types hardly overlap. For low resistances from 0.1 to 5.08 ohm the “J” Coil spirals are taken, for smooth manual regulation the Bercostat rheostats, and for high power up to 1080 W the tubular slider-type resistors. If voltage regulation is needed rather than resistance, an autotransformer is better than a rheostat.
