Watt-Hour Meter (PM-1000
Series)
TRIATEK's PM-1000 Series Watt-Hour
Meter measures power in Watts-Hours and provides a
pulse output proportional to energy consumption.
Utilizing three current transformers and up to 480
volt service on single and polyphase power systems,
the unit performs necessary factoring and math functions
to calculate energy use in Watt-Hours. Watt-Hours
are transmitted as a dry contact closure rated at
120V, 0.3A, -10VA maximum for remote control or monitoring
applications. The standard Watt-Hour calculation factor
is calibrated to output 5 watt-hours per count. However,
to increase the pulses the unit can be ordered with
other Watt Hour per count factors. The equation for
determining KWH is the potential transformer ratio
multiplied by the current transformer ratio multiplied
by the Watt-Hour/Count ratio divided by 1000. For
example, if there is no potential transformer and
if the current transformer ratio is 600:5, and the
Watt-Hour/Count is 5, then the KWH value per closure
on the PM-1001 would be 0.6 KWH (600÷5)*5)/1000.
The PM-1000 Series Watt-Hour Meter is housed in a
general purpose enclosure for mounting in a panel
or on a flat surface.
