SX460 : Most popular Genset AVR module, high quality but very reasonable price!

AS440 : AS440 AVR is the new model that replacing SX440 Geneartor AVR . Original SX440 Genset Voltage Regulator had been discontinued, but we still have SX440 in stock. Stamford AS440 AVR is a half wave phase controlled thyristor type AVR and forms part of the excitation system for a brush-less generator. The design employs Surface Mount Technology (SMT) for high integration of features in a small footprint AVR.

AS480 : The Stamford AS480 AVR for Generator is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.0%. The AVR voltage sensing terminals continuously sample the output windings for voltage control purposes. In response to this sample voltage, the AVR controls the power fed to the exciter field, and hence the main field, to maintain the machine output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator.

SX440 : Original SX440 Genset Voltage Regulator had been discontinued, but we still have SX440 in stock. INPUT : Voltage 190-264V ac, Frequency 50-60 Hz nominal, Phase 1, Wire 2. OUTPUT: Voltage max 90V dc at 207V ac input, Current continuous 4A dc, Intermittent 6A for 10 secs, Resistance 15 ohms minimum

MX341 : Stamford MX341 AVR is a two phase sensed Automatic Voltage Regulator and forms part of the excitation system for a brush-less generator. Excitation power is derived from a three-phase permanent magnet generator (PMG), to isolate the AVR control circuits from the effects of nonlinear loads and to reduce radio frequency interference on the generator terminals. Sustained generator short circuit current is another feature of the PMG system.

MX321 : The MX321 AVR for Stamford Generator senses the voltage in the main generator winding and controls the excitation to maintain the generator output voltage within the specified limits, compensating for load, speed, temperature and power factor of the generator.

R250 : Most popular AVR module, high quality but very reasonable price!

R230 : Original R230 had been discontinued and replaced by R250 AVR, but we still have R230 (Replacement) in stock.

R438 : Leroy Somer R438 Generator Voltage Regulator is an analog AVR. It is designed for alternators with a AREP or PMG excitation. Leroy Somer R438 AVR controls the excitation current in order to maintain the output voltage of the alternator.

R448 : Original R448 and R449 had been discontinued and replaced by R450 AVR, but we still have R448 (Replacement) in stock.

R449 : Original R448 and R449 had been discontinued and replaced by R450 AVR, but we still have R449 (Replacement) in stock.

R450 : R450 AVR for Leroy Somer Generator is an analog A.V.R.. It is designed for alternators with a SHUNT, AREP or PMG excitation . R450 Leroy Somer Voltage Regulator controls the excitation current in order to maintain the output voltage of the alternator. Leroy Somer R450 is performant in terms of voltage regulation, simple to set, to use and is reliable.

R450M : The Leory Somer R450M AVR has all the same functions with R450, but R450M have special connectors, you can see the details of connectors from the photos in our website.

SE350 : Most popular AVR module, high quality but very reasonable price!

DVR2000E+ : The Marathon DVR2000E+ genset voltage regulator is a new model that can replace DVR2000E AVR. DVR2000E+ has REMOTE CONTROL function, but DVR2000E has not.

DVR2000E : The Marathon DVR2000E AVR was discontinued, there are 3 options for DVR2000E AVR:

Option 1: Use our replacement model for DVR2000E (All the same function, 1 year warranty, best choice. )

Option 2: Use Original Marathon AVR DVR2000E+ (More functions but more expensive too)

Option 3: Use Original Basler AVR BE2000E (same function but more expensive)

SR7-2G : Most popular AVR module, high quality but very reasonable price! Meccalte SR7 AVR a negative feedback system, in which the constantly maintained variable is the alternator voltage output. This voltage, after adequate conditioning, is compared with a signal that is stabilised in voltage, temperature and age. The result is an error signal which, when opportunely amplified and compensated, produces a control level that enters an impulse width modulator.

UVR6 : The Mecc Alte UVR6voltage regulator is an advanced design electronic regulator that ensures excellent performance of the Alternators while they are running and during starting. The regulator is equipped with a complete protection system against operation conditions that could be dangerous for the machine.

SR7-1, SR7/1 : The Mecc Alte SR7-1, SR7/1 AVR was discontinued and replaced by SR7-2G now.

DSR : The Mecc Alte Generator AVR DSR is a voltage regulator for synchronous alternators, designed for stand alone working and calibration; to maximize performance, the regulator should be understood as part of a system made up of at least three components: the DSR (control unit), a communications module (USB2DxR, for example) and a supervision unit.

DER / DER1 / DER 1A :The DER1 is a voltage regulator for synchronous alternators, designed for stand alone working and calibration; to maximize performances, the regulator should be intended as part of a system made up of at least three components: the DER1 (control unit), a communications module (USB2DxR, for example) and a supervision unit.

The ASR AVR for Mecc Alte generator Voltage Regulator is a closed loop automatic voltage 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 Mecc Alte DER2 AVR is a voltage regulator for synchronous alternators, designed for stand alone working and calibration; the connectors for connection to and from the power generator and to the supervision unit are located on the DER2 regulator.
