Product Description

Generator Parts AVR Automatic Voltage Regulator R449 For  Generator Load Acceptance Control Module Parts   



SPECIFICATIONS:
Normal AVR supply power: 2 auxiliary windings
(X1, X2, andZ, Z2)
Shunt supply: 150V .50/60Hz
Rated overload current: 15A, 10s.
Electronic biltlin (overload, short circuit, and loss ofsensing) protection: If excitation current raises over 10Amps for more then 10 seconds, excitation current will drops automatically to about 1A.
To reset AVR protection, generator must be stopped (or by cutting supply voltage to the AVR).
Protection of power inputs by fuses F1
Vollage sensing: 5VA insulated transformer with input
voltage taps at:
Terminals 0-110V = 95 to 140V
Terminals 0-220 V= 170 to 260 V
Terminals 0-380 V = 340 to 520V
Output Vltage adjustment by using pot P2
Other sensing vltages by using an adapting other transformers
Curent sensing (arall operation) CT 2.5 VA class 1 secondary current oo/1 (optional).
Adjustment of quadrature droop with pot P1
Under-speed (U/F) and LAM protection: for knee frequency adjustable use P4.
Excitation over crrent adjustment use P5: 4.5 to 15A For 50/60 Hz (U/F) solection use jumper ST3.
Load acceptance module:
LAM is suppressed by cutting wire marked ST5 LAM (Load Acceptance Module) function.
When applying a step load to the generator, the rolational speed (frequency) of the genset drops.
I the speed is below the preset frequency the "L AM circuits drops the voltage about 15% and this way reducing the effective step t about 25%.as long as the speed has not recovered to normal values.
The "LAM" is used either to reduce the speed drop of the engine, during the step load, or to increase the applicable step load for the same speed variation (turbo charged engines) so the engine can recover normal speed quickly.
To prevent ollage silltions, the frequency threshold must be adjusted about 2 Hz below the lowest frequency in normal operation.
