Phase Converters

For larger woodworking and automotive workshops, 3-phase power is a necessity. Machine equipment, compressors, fans and dust collectors, pumps, etc, with motors in excess of 5hp generally require 3-phase electrical supply.

For my projects, I've found that Phase Perfect® digital phase converters, developed and patented by Phase Technologies, LLC, provide a safe and efficient means of generating stable 3-phase power. These converters with their solid state design are exceptionally compact in size and consume minimal power when energized under idle conditions (ie, without load).

Common features include....

Balanced three-phase power under all load conditions for even the most demanding applications

Pure sine wave output voltage allows operation of the most sensitive equipment

Electronic power factor correction to near unity (.99) under all load conditions

97% efficiency typical

Under-voltage protection - auto shutdown at <187v, resets to ON @ 199v>

Over-voltage protection - auto shutdown at >255v, resets to ON @ <255v

Simple to configure and install

All Phase Perfect® converters are UL certified

Three models are currently available to accommodate a variety of needs...

DPC-A10 (10hp) - $2,650.00 (+$49 freight*)

DPC-20 (20hp) - $4,160.00 (+$99 freight*)

DPC-30 (30hp) - $5,940.00 (+$149 freight*)

*Flat rate shipping anywhere in the Continental US (terminal pickup or commercial address). Residental delivery and tailgate services extra.

DPC-A10 (10hp) - this converter is ideal for most home workshops with a small number of 3-phase loads (1-3) that would typically not all be running at the same time. I use this model for my Kaeser compressor, Nussbaum lift and for a pair of exhaust fans with speed control.
