Product Name:Voltage Regulator AVR R438

Voltage Regulator AVR R438

Application

Unversal

Product Description:

Specifications 

> Voltage regulation +/- 0.5 % at steady state and constant speed.
> Phase to phase voltage sensing.
> Control by transistor means the regulation quality is independant of load applied.
> Integrated "LAM" system to cope with increased loads applied to the engine

> Suitable for high levels of vibration and harsh environments.
> The R 438 is compatible with other modules giving additional functions. 

> Standard power supply: AREP or PMG.
> Rated overload current: 8 A - 10 s
> Electronic protection (overload, shortcircuit on opening of voltage sensing circuitexcitation overload current for 10 seconds then return to approximately 1A.

> Fuse : F1 on X1, X2. 8A ; slow - 250V
> Voltage sensing : 5 VA isolated via transformer;
> 0-110 V terminals = 95 to 140 V,
> 0-220 V terminals = 170 to 260 V,
> 0-380 V terminals = 340 to 520 V.
> Voltage regulation ± 1%.
> Normal or rapid response time via ST2 jumper
> Voltage adjustment via potentiometer P2

> Current sensing (parallel operation): C.T. 2.5 VA cl1, secondary 1 A (optional).
> Quadrature droop adjustment via potentiometer P1
> Max. excitation current adjustment via P5
