DYNAMIC BRAKING RESISTORS

Dynamic braking resistors provide a means of rapidly decelerating or stopping the motor and load. The mechanical energy stored in the spinning mass is converted into electrical energy by the drive and then quickly dissipated into the resistor, (See Power Accessories section for braking resistor ratings and model numbers)

INTERNAL EMC FILTERCommander SK Internal EMC Filter

An internal EMC filter is provided as standard with the Commander SK which is adequate for most industrial applications. The drive and filter conforms to EN61800- 3 (second environ- L ment). For installations where it is deemed necessary, Control Techniques provide a range of addition external EMC filters. The internal filter can be easily removed if the drive is to be used on IT supplies or with low earth leakage external EMC Footprint filters.

EXTERNAL EMC FILTERS

EMC filters are used to minimize high frequency power supply line disturbances caused by PWM AC drives that may interfere with proper operation of sensitive electronic equipment. These specific filters have been assessed for conformance with the EMC directive by testing with the appropriate Control Techniques drives. Commander SK 2 Mounting Styles in One

TWO MOUNTING STYLES IN ONE

The Commander SK EMC filters are designed such that they can be mounted in either of two orientations.

  • Bookend: filter mounts next to the drive with the smallest dimension being the width of the filter
  • Footprint: filter mounts between the drive heatsink and the panel or enclosure
