ELECTRONICSUPPLYSYSTEMSRECTIFIER SERIESB2, B5, PS - 2

A number of modules, ranging from simple circuits with classic designs, to complex assemblies ensuring quick action and drives positioning have been designed to drive the brakes. Relevant brake applications with switching in the primary or secondary circuits are ensured by half- or full-wave rectifiers and fast electronic circuits. The manufacturer recommends to use as low alternating current voltages as possible to supply the brakes. Appropriate choice of the control voltage will prevent or at least limit surges that may occur in power supply circuits. It is not recommended to use...

ELECTRONICSUPPLYSYSTEMSRECTIFIER SERIESB2, B5, PS - 3

Disconnection of power supply on AC side The diagram presents connection of rectifiers to supply circuit of motor. When disconnecting the voltage, the magnetic field causes the coil current to flow further through the rectifying diodes and drops slowly. The magnetic field reduces gradually causing prolonged time of braking action and consequently delayed increase of braking torque. If action time is irrelevant, brake should be connected on the AC side. When switching off, the supply circuits act as rectifying diodes. Disconnection of power supply on DC side The diagram presents connection...

ELECTRONICSUPPLYSYSTEMSRECTIFIER SERIESB2, B5, PS - 4

Rectifier PS-1 Circuit PS-1 is built on the basis of MOSFET type semiconductor technique which enabled achieving effects not available in traditional designs. The brake electromagnet energized through circuit of this construction enables the brake to achieve connection and disconnection time parameters analogous to breaking of circuit on direct current side. The parameters obtained are not however gained through utilization of additional electrical circuits and switches. Simplicity of installation and parameters achieved enable very wide application, particularly in cases requiring...
