Don't operate your backup or alternative power electrical system blind!
Install and connect this high-tech microprocessor controlled meter to easily
monitor your electrical loading at a glance.
NEMA 1 enclosure is 8" x 8" x 4" deep, made of #16 gauge steel
and comes with 1/2", 3/4" and 1" knockouts. Hinged front cover is
supplied ready for cutting rectangular hole to mount meter. Enclosure is UL Listed and
CSA certified. For maximum meter life we do not recommend direct mounting of
enclosure on engine driven generators due to vibration. Mount separately on an
indoor wall.
Two voltmeter indicators and two wattmeter indicators provide
simultaneous display of parameters for both hot legs of a 120/240VAC system.
Meter is rectangular, 5% accuracy and fits into rectangular hole in cover and
is held in place with an included metal spring clip. Barrier type terminal block included for easier wiring. You must
cut hole for meter and mount
and wire components. Depending on the type of wire, you must supply properly sized
cord grips or strain relief connectors.
Operation
Voltages from the generator, voltages from the generator current sensors, and a voltage
from the utility mains are applied to the appropriate inputs to the meter. The meter
acquires these signals, performs scaling and other math functions, and outputs voltage
and real power (wattage) results to the display board by lighting particular LED
segments. The power is calculated internally by multiplying the amps and
volts with an assumed power factor of 1.0.
The outboard LEDs display generator voltage. A green LED indicates the generator
voltage is within +/- 5% of 125 VAC, a yellow LED indicates within +/- 10%, and a red
LED indicates a voltage outside of +/- 10%.
The inboard LED bar graphs display generator power. The segments are marked with
their appropriate wattages to a resolution of approximately 5% of maximum power.
Segments are green up to 85% of maximum power. Between 90% and 100%, the segments are yellow. A red segment indicates power draw
above 100%.
