Rectifier - Power Collection

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.

These compact half-wave and bridge rectifiers are ideal for installation in space restricted junction boxes of brake motors. They can be delivered with flying leads or terminals for connection. Various accessories are available to meet different installation requirements.

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.

Thanks to extremely compact design the overexcitation rectifier "Slim Collection" can be installed in very restricted space. The module features a central bore for screw fixing inside the terminal box. It can also be installed by using an adhesive pad.
