  • Motor Termination Units

    Hilkar

    Since the rise time of IGBTs are in the range of a few tens of nanoseconds (between 50ns-200ns), even short cables between PWM motor drives and motors cause voltage doubling at the motor terminals due to Travelling Wave Phenomenon as in transmission lines. The insulation of motor windings are prone to failure due to high voltage spikes if necessary precautions are not sufficiently taken. RC Type Output Filter Modules reduce these high voltage spikes to protect motors by connecting to stator terminals.

  • Reservoir Isolators

    Parker Hannifin Corp.

    Fluid contamination can lead to high maintenance costs and downtime in hydraulic systems. Parker reservoir isolators provide protection against the ingestion of airborne contaminants such as dust, chemicals and water vapor through the breather-vent of your hydraulic system. Utilizing an elastomer bladder as a lung, the changes in gas volume in a hydraulic system's reservoir can be trapped and prevented from mixing with the outside atmosphere. Unlike conventional breather-vent filters, Parker reservoir isolators provide a positive separation without the possibility of clogging or need for maintenance.
