In SHUNT excitation systems, the AVR power supply and voltage reference are picked on the same output terminals. The AVR generates and regulates the excitation current as a function of the alternator output voltage. The SHUNT system is extremely simple in its design and is ideal for standard applications. AREP or PMG systems

Starting kVA up to +35% compared to a traditional AREP excitation system; A faster excitation chain with a response time lowered by up to 30%; A faster start of the regulation, from 600 rpm / 20 Hz; Lower voltage drop at machine terminals

The D550 digital automatic voltage regulator (AVR) provides excitation current up to 8 A with excellent reliability and precision for SHUNT, permanent magnet (PMG) or AREP (auxiliary winding) excitation types.

AVR 4531 en - 2 - POWER SUPPLY Both the SHUNT/AREP & PMG excitation systems are controlled by the AVR. 2.1 - AREP excitation system With AREP excitation, the electronic AVR is powered by two auxiliary windings which are independent of the voltage sensing circuit. The first winding has a voltage proportional to the alternator main voltage (Shunt

2020年6月14日 · AREP (Auxiliary Winding Regulation Excitation Principle) is a patented technology owned by Leroy-Somer. In AREP excitation systems, the AVR power supply comes from two...

The D350 digital automatic voltage regulator (AVR) for industrial alternators provides excitation current up to 5 A with excellent reliability for SHUNT, permanent magnet (PMG) or AREP (auxiliary winding) excitation types. D350 includes advanced protections such as over-excitation limitation and voltage sensing loss.

PMG and AUX Windings (also known as AREP windings) are two different systems designed to provide power to the AVR independently from the generator – thus maintaining generator’s ability tosupport

2.1 - AREP excitation system For both AREP & PMG excitation systems, the alternator voltage regulator is the R 448. With AREP excitation, the R 448 electronic AVR is powered by two auxiliary windings which are independent of the voltage match circuit. The first winding has a voltage in proportion to that of the alternator (characteristic

2021年4月26日 · With a PMG (Permanent Magnetic Generator) system, the energy to power the AVR is generated by rotating magnets external to the alternator. This system constitutes an almost constant source of energy, allowing the AVR to quickly balance the generator’s voltage, according to the pre-established voltage.

R450 AVR FOR SHUNT, AREP or PMG ALTERNATORS R450 is an analog AVR. It is designed for alternators with a SHUNT, AREP or PMG excitation. R450 controls the excitation current in order to maintain the output voltage of the alternator. R450 is performant in terms of voltage regulation, simple to set , to use and is reliable.
