Power resistors are used in the braking circuit of the inverter wherever high dynamics of drive braking is required and in drive systems e.g. lifts, cranes, winch cranes, presses and spindle drives, where fast acceleration and fast braking or a quick change of rotational speed are required. They are adapted to receive and dissipate high power. The dimensions of the resistor depend on its power and resistance value.
We produce and sell resistors with different powers, resistances and IP protection levels. On special order we also produce resistors with unusual parameters and with forced cooling with both air and water.
Very good technical parameters and low prices make our resistors very competitive comparing to those produced by other manufacturers.
