Q: SX440 generator excitation adjustable clamp and what is the difference between AS440 generator voltage regulator?

A：SX440Generator excitation adjustable clampCompatible AS440AVR, also compatible AS480The generator voltage regulator，The difference is on the auxiliary input SX440 a weaver, no weaver AS440 auxiliary input.But AS440 for more than 200 kw generator set, but the basic functions are similar.

There is also a SX440 generator excitation adjustable clamp has three colors, red, blue, grey.Different color the price also different.Because no color electronic component is different.
