We are instrumental in offering our clients a wide variety of Resistance Boxes PS/SS, which are meant for adding resistance into both AC and DC electric motor circuits. In turn, these boxes help in enhancing the performance of slip ring electric motors, installed in EOT cranes, rubber mills, steel rolling mills, cement mills, power plants, conveyors, coke oven, blowers and so on. Further, these boxes control the speed by developing starting torque with low starting currents. These may also serve as dynamic breaking resistors for VVVF AC drives and electric loading of AC alternators, DC generators & dynometers.
