SPPS introduces its 50 HP 1-to-3 Microgrid Power Source, which generates clean, stable three-phase power from single-phase utility power. Single Phase Power Solutions introduces the 50 HP 1-to-3 ...

The cost of upgrading single-phase service to three-phase service is currently $7 to $10 per linear foot, from the nearest existing three-phase power line in the neighborhood.

This is because single-phase current is 1.87 times the 3-phase current for the same power. Voltage swell or overvoltage. Voltage-source PWM drives use a DC capacitor to smooth the rectified line ...

The Corcom brand single- and three-phase filters are designed for high current applications ranging from 30-400 A. The new BCF Series includes seven three-phase filters with current ratings of 30-180 ...

I’m not entirely sure, but the single phase board seems to have a voltage divider sized for 110VAC max, not RMS (110 *4.7/259.7 = 1.99V max input on the VP and VN pins is spec’ed at +/-2V).
