Description
The PMG series includes fast-switching rectifiers designed to optimize the operation of electromagnetic spring-applied brakes in demanding industrial applications.
By switching from bridge rectification to half-wave rectification after an initial boost period, PMG rectifiers enable faster brake release and reduced power consumption during holding operation. Available in different voltage configurations, including versions with integrated quick shutdown, the series provides flexible solutions for industrial braking systems requiring improved switching performance and efficient voltage control.
Key Features
-
Fast Brake Release: Increased excitation voltage helps reduce brake release times.
-
Automatic Voltage Switching: Changes from bridge to half-wave rectification after the initial boost period.
-
Reduced Power Consumption: Lower holding voltage helps limit energy consumption.
-
Reduced Thermal Load: Suitable for temperature-sensitive applications.
-
High-Torque Applications: Supports the release of brakes with high braking torque.
-
Integrated Quick Shutdown: Available in the PMGU version for faster brake engagement.
