Rectifier - Standard Line
Overexcitation rectifiers - intelligent and flexible
Description
The rectifier with built-in current sensor for fast turn-off is designed for the operation of electromagnetic devices. It ensures fast turn-on and turn-off. The rectifier with bridge circuit comprises a thyristor and timer. During overexcitation, the rectifier delivers bridge rectified output voltage before changing over to half-wave rectification. On the DC side, the output voltage is enabled by the built-in current sensor which measures the AC current of the connected motor. If the motor is stopped, the rectifier turns off on the DC side as soon as the current falls below the turn-off threshold. The turn-off voltage generated by the inductive load is limited. The rectifier is suitable for connection in parallel with AC motors. The current sensor must be wired into the motor current path in such a way that the current flow created when the motor operates in generator mode will not pass through the sensor. This is crucial to avoid delayed or impaired DC side switching.

These overexcitation rectifiers are designed to increase the attractive force and reduce the attraction time of actuating solenoids, to shorten the coupling and disconnection times of clutches and brakes and to decrease the power consumption of clutches, brakes and actuating solenoids. To increase the attractive force, the solenoid is overexcited during the overexcitation time, applying bridge rectified voltage. Then the rectifier changes over to the selected holding voltage which must not exceed the rated voltage of the solenoid.

ESM for AC-brakes: The module consists of a time-controlled rectifier with integral electronic fast turn-off. During start-up, the ESM delivers bridge-rectified output voltage before changing over to half-wave rectification. The built-in voltage sensor ensures that the DC side output voltage is interrupted electronically when AC input voltage is removed. Thanks to its compact design, the ESM can be installed in very restricted space. ESM for DC-brakes: The module keeps the voltage supplied to the electromagnetic device at a constant level over a wide input voltage and temperature range. Full operating voltage is applied to ensure fast switching when the load is switched on. The module then reduces the power supply to constant holding voltage. A 30% reduction provides power savings of 50%. The ESM is very compact thanks to the use of state-of-the-art microelectronic and power electronic components. Overexcitation time and holding voltage can be factory-programmed to customer demands.

These half-wave and bridge rectifiers are ideal for installation in the junction boxes of medium-power brake motors, brakes and solenoids. Accessories include flying leads and a range of mounting hardware so that installation on DIN rails is also possible. Encapsulated versions for an extended operating temperature range are available as options. In case of additional DC side fast turn-off, the induction voltage generated by inductive loads is limited within the rectifier.
