Motor
The Vari-Green Motor is an electronically commutated
(EC) motor that uses AC input power and internally
converts it to a DC power supply which provides an
80% turndown capability and increased energy savings.
NOTE
When using a clamp meter to measure input amp
draw, the meter must be capable of reading a
non-linear current. Erroneous readings will occur
otherwise.
