Rectifiers

7.1.3 OEX Switch Wiring Diagrams

The OEX Rectifier excites the brake magnet with the nominal voltage and then reduces
the voltage by 50% for holding. This reduced holding voltage significantly reduces the
power consumption and speeds up the engagement of the brake when the voltage is
switched off.
