Power rheostat - 25 - 500 W | FVR series
The MFPS high power rheostats rotary variable power wire wound resistors are heavy duty rheostat load boxes which feature resistance ranges from 25W, 50W, 100W, 300W and 500W. As rheostats do not have a standard resistance value, all are designed and manufactured to a customer's specific requirements. Different load currents and resistance ranges require different resistance materials to withstand the current and achieve the resistance value. In terms of rated power, a smaller rated resistance value means that the rheostat can have an increased rating regarding the maximum current capacity. For power larger than 3kW, please refer to MFPS's tandem mounted rheostat bank. Standard features include an ammeter, a voltmeter, a wattmeter, an over current protection, a thermal protection and a cooling fan system. It is improtant to note that consulting the factory about your specific needs is recommended, as any products needed will be designed and constructed to these requirements
