## Overview

The ZJTIN Automatic Voltage Regulator Module R438 is engineered for brushless generators, offering a robust voltage regulation solution with a wide input range of 95-480V AC. Its durable construction and compatibility with AREP/PMG excitation systems make it an essential component for reliable generator performance.

## Description

R438 Permanent Magnet Generator or A.R.E.P or Auxiliary Winding type generator voltage regulator is a compatible replacement for R448, R449, R438, and AEM110RE016 and also 922 124.  The circuitry of the R438 Automatic Voltage Regulator (AVR) provides closed loop contro of the generator output voltage by regulatin exciter field current,R438 can be powered by EREP or PMG field excitation system and fitted as an option on:  -100series generators  -200series generaotors  -300series generators  With the AREP excitation system the R438 AVR is powered by two auxiliary windings which are independent of the voltage detection circuit.With the PMG option the R438 AVR is powered by the PMG which is fitted ar the rear end of the generator.  Voltage Regulation < ±0.5%  Load Acceptance Module (LAM)  50/60 Hz Selectable  Under Frequency & Exc. Max Protection  Single Phase Or Three Phase Voltage Sensing Optional  Soft Start Voltage Ramping  Normal Rapid Response Time (Option)  Voltage Sensing: terminal 0-110V=95-140V  terminal 0-220V =170-260V  terminal 0-380V=340-520V  Frequency: 50-60Hz  Voltage input: 40-50VAC, 3 phase  Harmpnic auxiliary winding :6-150VAC (no-load rms)  Output:  Voltage: max 160VDC at 120VAC input  Current: max 8A  Resistance:15 Ω minimum  Regulation:+/-5% RMS with 4% engine governing  Voltage establish:residual voltage at avr terminal≥ 5AC  External Voltage Adustament:+/-10% with 1k ohm 1 watt trimmer
