Advantages of Brush Prismic ® Power Management System

BRUSH Power Generation offers a range of standard excitation systems and bespoke systems designed to suit the customer’s needs.

Standard Product

• PRISMIC® A3100

The PRISMIC® A3100 includes two fully featured independent controllers and two independent power circuits within a single 6U 19-inch enclosure, all available as removable cards (single channel option available).

The A3100 builds on previous experience and technologies from BRUSH Power Generation, incorporating features such as an 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 BRUSH Power Generation controllers the A3100 is an easy replacement of previous BRUSH Power Generation AVRs such as the MAVR, MicroAVR, A30, and even the A32.

BRUSH Power Generation can provide engineering expertise to help replace other OEM Brushless AVRs up to 20A rating with the A3100.

.

• PRISMIC® A32

The PRISMIC® A32 excitation controller or automatic voltage regulator (AVR) includes two fully independent controllers and two independent power circuits. The PRISMIC® A32 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.

• PRISMIC® A12

The PRISMIC® A12 excitation controller, designed to control the excitation of a brushless generator, uses the latest digital microcontroller technology to make it the most compact unit in the BRUSH Power Generation range. The PRISMIC® A12 is provided on a mounting plate, complete with wiring loom and auxiliary equipment.

Static & Bespoke Excitation Systems

• PRISMIC® A50

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 20A to over 8000A.

Monitoring Systems

• PRISMIC® R10

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 slip rings, resulting in enhanced reliability and reduced maintenance costs.

Power System Stabiliser

• T20

Power system stabilizer functionality is included within the latest BRUSH Power Generation excitation controllers, however, the T20 provides this functionality in a separate unit suitable to be used with simpler excitation controllers.
