Description

Leroy Somer AVR,Automatic Voltage Regulator R438


R438 AVR is for LEROY SOMER LSA 42.2, LSA 43.2, LSA 44.2 alternators with AREP excitation.

AVR Characteristics
- Standard power supply: AREP or PMG.
- Rated overload current: 8 A - 10 s
- Electronic protection (overload, short- circuit on opening of voltage sensing circuit): excitation overload current for 10 seconds then return to approximately 1A.
- The alternator must be stopped (or the power switched off) in order to reset the protection.
- 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 (see below).
- Voltage adjustment via potentiometer P2 other voltages via adapter transformer
- 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.
- Applications to Alternators: LSA 42.2,43.2,44.2
- Compatible with the AREP or PMG exitation system
