Leroy Somer Alternator Spare Part Automatic Voltage regulators avr R450

 

 

AVR for Brushless Generator R450

 

 

 

Features:


1. Leroy SomerAutomatic Voltage Regulator R450

2. Single or three phase voltage sensing with optional module.
3. Load acceptance module, PMG / AREP excitation system
4. Phase to phase voltage sensing.
5. Suitable for high levels of vibration and harsh environments

 

 

Main characteristics:

 

1.Voltage regulation +/- 0.5% at steady state and constant speed.

2. Control by transistor means that the regulation quality is independant of applied load.

3. Phase to phase voltage sensing.

4.Suitable for high levels of vibration and harsh environments.

5. Integrated "LAM" and " auto adaptative LAM" system to cope with load impacts applied to the engine

6. AREP or PMG excitation with normal or fast response.

7. Single or three phase voltage sensing with optional module.

8. Rotating switch facilitating selection.

 

Description:

 

Leroy somer R450 AVR is powered by two auxiliary windings which are independent of the voltage equal circuit. The power supply voltage is rectified and filtered before being used by the AVR monitoring transistor. With PMG excitation, a permanent magnet generator (PMG) added to the alternator supplies the AVR with voltage.

 

On Application of load, the rotation speed of the generator set deceases, when it passes below the preset frequency threshold the LAM causes the voltage to drop by approximately13% or 25% and consequently the quantity of active load applied is reduced by approximately 25% to 45%, until the speed reaches its rated value again. Hence the LAM can be used either to reduce the speed variation (frequency) and its duration for a given applied load, or to increase the applied load probable for one speed variation (turbo-charged engine).
