Brake control unit BUT-20-380 is designed for supplying power to solenoid circuit of electromechanical brake positioned on motor shaft.
BUT is a variable converter with DC output link, which power circuits are fed from a 3-phase network 380V 50Hz. By means of pulse-width modulation an impulse voltage of a preset average value is generated at the BUT output. The output is connected to electromechanical brake electric solenoid.
