Introduction
The MillipaK 4QPM (Four Quadrant Permanent Magnet) range of controllers provides a new
range of power frames for 24V-48V, 330A in small, highly efficient packages. This is achieved
using a Sevcon patented power switching scheme and radical new construction techniques, which
enable large powers to be incorporated into very small packages.
The MillipaK provides a completely sealed (IP66) unit containing both power and logic circuitry,
as well as all suppression components and an optional integrated pump soft start/stop chopper.
MillipaK supports Sevcon's existing MOS90 calibrator for adjustment of vehicle performance
characteristics. MillipaK is ideally suited to applications requiring a single traction controller, for
example walkies, golf cars and basic ride-on trucks.
Controllers are FLASH microprocessor based enabling field re-programming for new features and
have numerous user set-up options. The MillipaK uses high frequency (silent) MOSFET power
switching technology, to control a 4Q power frame bridge. Armature current is monitored. Motor
feedback should not be necessary. Controllers have been designed to satisfy the requirements of
the relevant UL and EC standards.
