SPM Benefits SPMD
Build custom high power systems using
volume produced power modules, with
proven reliability and short lead time. The
compact, innovative, IP modules are SPMC or
physically easy to handle and install. SPMU
Cleaner power by minimising input harmonics with ,
or pulse rectifiers or eliminate harmonics with an active
input configuration.
Control dynamic loads with the inbuilt brake controller or full
regenerative energy control with an active input.
Reduce running costs by circulating energy between braking and
motoring drives on a common DC bus system and by returning
excess energy to mains supply with an active input.

The modular nature of the power circuit allows drive systems to

possible to implement a drive system of between and
kW in an enclosure no taller than 1m. This would be
achieved by mounting the drives, rectifiers and inductors side by
side. This is of great interest for crane hoists, deep mine

Optimise Spares Inventory
The possibility of standardising on a single, compact drive module is highlighted by
the following schematic. It is based on an actual marine project that incorporated
a wide range of applications and motor ratings, but with each one implemented by
various combinations of SPMA.
In addition to minimising spares inventory, this approach also standardises the system
build, with many of the cubicles being identical.
