Advantages

The Dellner FWR (Full Wave Rectifier) and HWR (Half Wave Rectifier) are critical components in brake control systems that convert alternating current (AC) into direct current (DC) to effectively manage power supply for electromagnetic brakes. Full Wave Rectifier (FWR): This component converts the entire AC waveform into a smooth, unidirectional DC current, ensuring efficient power conversion for applications that require consistent and robust DC power for brake operation. Half Wave Rectifier (HWR): In contrast, the HWR converts only half of the AC waveform into pulsating DC, making it suitable for applications that require a simpler, less powerful DC supply for effective brake function. Both rectifiers play a vital role in controlling the engagement and release of electromagnetic brakes, enhancing the overall performance of braking systems. Dellner’s rectifiers are designed for easy integration, often mounted in junction boxes or directly on DIN rails to facilitate seamless installation in various setups.
