R438 AVR Generator Automatic Voltage Regulator Diesel Alternator Control Board Stabilizer AVR for Brushless Genset Spare Part

AVR R438

An automatic voltage regulator (AVR) is an electronic device
that maintains a constant voltage level to electrical equipment
on the same load.
The AVR regulates voltage variations to deliver constant,
reliable power supply.

Product Description

Fuse: F1on X1,X2.10A;slow-250V

Voltage sensing : 5 VA isolated via trans- former • 0-110 V terminals = 95 to 140 V • 0-220 V terminals = 170 to 260 V • 0-380 V terminals = 340 to 520 V for other voltages, a transformer should be used.
Voltage regulation ± 0.5%
Normal or rapid response time via jumper ST2 (see below)
Voltage adjustment via potentiometer P2 or apply a DC voltage of ± 1 V on the terminals of the external potentiometer
Current sensing: (parallel operation): input S1, S2 intended for 1 C.T. Š 2.5 VA cl1, secondary 1A (optional)
Quadrature droop adjustment via potentio- meter P1
