Universal AVR Voltage Regulators

Universal AVR voltage regulators are used to regulate the output voltage of brushless alternators. Its operation consists of controlling and sending the excitation current of the generator. In this way, the output voltage between frequency and load ranges, which are already pre-established, is kept constant.

All AVR voltage regulators available in our catalog must be installed and handled by personnel with sufficient qualifications (according to EN-50-110-1).

In our product selection you will find Automatic Voltage Regulators (AVR) compatible with STAMFORD and LEROY SOMER regulator models for brushless alternators.

Voltage regulators (AVR) compatible with STAMFORD regulators

Our voltage regulators compatible with STAMFORD regulators incorporate different utilities such as: protection against low frequency (UFRO) signaled by LEDs; possibility of working in parallel; inlet for special applications; internal potentiometers and protection against loss of sensing.

These products comply with the provisions of the Electromagnetic Compatibility Directive (CE: 2004/108 / CE) and with the Low Voltage Equipment Directive (73/23 / CEE).

Voltage regulators (AVR) compatible with LEROY SOMER regulators

Our voltage regulators compatible with LEROY SOMER regulators have a standard power system, available in AREP or PMG version; or with the Shunt power or excitation system.

AREP power supply: the electronic regulator is powered by two independent auxiliary windings of the voltage detection circuit.

PMG power supply: the regulator is supplied with a constant and independent voltage from the main winding of the alternator.

Shunt power supply: the regulator controls the excitation intensity of the exciter according to the alternator output voltage. Very simple in design, the shunt-excited alternator has no short-circuit capacity.

All of our automatic voltage regulators contain electronic components inside. Do not use high voltage meggers or testers, as they may damage the equipment.
