The ASR is a closed loop AVR regulator system, that controls and keeps constant the alternator output voltage. The output voltage of the alternator is monitored and confronted with a reference signal: the difference between the two is used to control the conduction state of an SCR.

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.

AVR Cards (Automatic Voltage Regulater) still operate on more than 2.500 generators. An extra setting at 50HZ, 60 HZ and 400 HZ frequencies is unnecessary.

An AVR keeps your generator and electrical devices safe by maintaining a steady voltage level. While power supply voltages might fluctuate, the AVR delivers consistent voltage to your device. Some benefits of an AVR for your equipment include:

EA63-5 is an automatic voltage regulator (AVR) for AMG synchronous generator industrial application series. The AVR is typically supplied by a single-phase auxiliary winding wound into the stator slots. It also can be supplied by permanent magnet generator ÄPMG Åor phase voltage of main terminal. 1.2 SPECIFICATION

The D550 is a digital automatic voltage regulator (AVR) for alternators with rated field current up to 7 A. It offers a vast array of regulation modes suitable for all power generation applications, including grid-connected configurations.

2019年6月14日 · Every train is fitted with alternators to generate electrical power and each one has an automatic voltage regulator (AVR) card that ensures the correct voltage is produced. However, in some cases, reliability has become an issue for these cards, which has led Sulzer to develop a service to repair or redesign and manufacture replacement AVR cards.

2024年3月9日 · AVR is an important part of a generator; if it fails, the generator could stop working. An AVR (automatic voltage regulator) helps keep the generator’s voltage output stable and within acceptable limits. You can detect faulty AVRs in …
