We provide a wide range of standard Brush Power Generation PRISMIC® excitation systems as well as bespoke systems designed to suit any customer’s needs.
The PRISMIC A3100 includes two fully featured independent controllers and two independent power circuits in a single 6U, 19-inch enclosure, all available as removable cards (single channel option available). The A3100 builds on decades of experience and technologies, incorporating features such as integrated power system stabilizer, automatic synchronizer, R10 ground (earth) fault receiver, ethernet and USB connectivity integrated into a single standard 19-inch rack package. With most connectors completely compatible with earlier controllers, the A3100 is an easy replacement choice for MAVR, MicroAVR, A30, A32, and other previous AVRs.
The PRISMIC A32 excitation controller or automatic voltage regulator (AVR) includes two fully independent controllers and two independent power circuits. It is one of the first excitation controllers to provide features such as an integrated power system stabilizer, a color TFT display, and ethernet connectivity. It is mounted within a single 6U, 19-inch enclosure.
The PRISMIC A12 excitation controller, designed to control the excitation of a brushless generator, uses the latest digital microcontroller technology to make it our most compact unit. It's provided on a mounting plate, complete with wiring loom and auxiliary equipment.
Static and bespoke excitation systems
The PRISMIC A50 provides stable voltage regulation with high reliability using advanced microprocessor and software technologies. Systems are available to satisfy generator excitation current ratings from under 20 A to over 8,000 A.
The PRISMIC R10 rotor earth fault monitor (REFM) uses an electronic unit to detect a single earth fault and dispenses with the need for brushes and sliprings, resulting in enhanced reliability and reduced maintenance costs.
Power system stabilizer
Power system stabilizer functionality is included in our latest excitation controllers. However, the T20 provides this functionality in a separate unit to be used with simpler excitation controllers.
