High Power 4 Quadrant PM Applications
The MillipaK series of controllers offer the most compact designs in the PowerpaK range and use new patented power technology and
PowerpaK switching principles. The MillipaK range offers a cost effective solution for low to high power applications such as pallet trucks,
sweepers, scissor lifts, golf carts and other electric vehicles fitted with Permanent Magnet DC motors.
The most striking characteristic of the MillipaK range is its physical size. The ultra compact design provides an unrivalled power – dimension
ratio which optimises the power /size / cost relationship.
The primary benefits of the MillipaK are as follows: –
♦ Contactorless Direction Changing – eliminating delays and the need for contactor maintenance.
♦ Adjustable Regen Braking – Regen braking on a conventional series motor typically requires additional electronic circuitry and a
solenoid contactor.
♦ Built-in Speed control – the MillipaK can control the motor in either Torque or Closed Loop speed control modes, selectable using the
diagnostic tools.
♦ Diagnostic and set-up tools – adjustments can be made using a handheld calibrator or via an RS232 connection to a computer running
the Sevcon PCpaK diagnostic software.
