Highly customisable architecture

All PPM 300 variants can be specified with 4 or 7 I/O module slots. The modules provide

voltage and current measurement, I/O, engine control, governor and AVR functions,

and communication. Three modules are mandatory, but you can use the remaining 1

or 4 slots to customise the controller by adding modules or leave them empty.

In addition, you can add up to 9 expansion racks to a single PPM 300 to get up to 58

free module slots (up to 4 in the base rack and up to 6 in each expansion rack).

Unique ANSI 87G differential protection

With the optional ACM3.2 module, you can add ANSI 87G differential protection for generators.

The module measures phase currents on the consumer and neutral sides of a generator in order

to detect phase-to-phase faults or phase-to-earth faults in earthed generator systems.

With this unique feature, you can design reliable and safe power systems without external

differential protection devices.
