Product Summary

The Model 348 is normally connected with only 4 wires. It comes factory set with a short form (B to A) terminals and the dip switches set for 208 – 240 volts 60 Hertz use. 1 OFF – 2 ON – 3 ON. In this configuration it works in almost all modern 12 wire generator sets from 190 to 277 volts and with exciter fields from 9 to 100 Ohms.

With the power and sensing input voltage connected together to terminals C & BA, and output terminals connected to terminals F+ and F-, it can work in almost any voltage configuration.

This AVR is "Universal" because it can also work with any 4 wire generator, at any voltage and Hertz, just by programming 3 simple dip switches located on the AVR. As long as you feed power to input terminals C&B with 100 to 300 volts and then connect sensing terminals C&A to the generator output voltage, you can make it work on almost any configuration.
