## Description

GENERIC REPLACEMENT SX440 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) and forms part of the excitation system for a brush-less generator. In addition to regulating the generator voltage, the AVR circuitry includes under-speed and sensing loss protection features. Excitation power is derived directly from the generator terminals. Positive voltage build up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR. The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulation of +/- 1.0%.

## Features

- Voltage 190-264V ac
- THERMAL DRIFT  0.04% per deg. C change in AVR ambient
- EXTERNAL VOLTAGE ADJUSTMENT +/-10% with 1 k ohm 1 watt trimmer
- BUILD UP VOLTAGE 4 Volts @ AVR terminals
- OUTPUT  Voltage max 90V dc at 207V ac input
