Enclosure rheostat / booster / mounted in tandem - max. 5 kW | FVRB series
MFPR's Rheostat Load Boxes of the FVRB series are heavy duty tandem rheostats. With a standard power range from 300W up to 5kW, for some applications the power range can be up to 20kW. In regards to rated power, a smaller rated resistance value means the rheostat can have a larger rated maximum current capacity. These load currents and resistance ranges require different resistance materials to withstand the current and achieve the resistance value. Features include a voltmeter, an ammeter, a power meter, a thermal protection, an over current protection, a control main switch, as well as a cooling system. As there is no standard resistance value suitable for all applications, the resistance is manufactured according to the customer's application needs, and the company will work with large or smaller customer orders.
