Aluminium case braking Resistors model HPRF

The resistors of the HPRF series are high-power resistors in an aluminium casing. HPRF resistors are intrinsically safe and short circuit-proof resistors for the operation in frequency converters. Due to their compact shape, further possibilities of application are possible. The best results are reached when the resistors can be mounted directly on a dissipator. Their form and design guarantee the maximal produce of the active material to reach an increased impulse stability as well as a high nominal permanent power at the same time. All materials are incombustible. The winding wire is in a water-proof cement core which furthermore reaches a high thermal conductivity and a high insulation.
