Shark® 50 meter
The Shark® 50 meter is similar in functionality
to the Shark® 100 meter, except that it is a
0.5% class energy meter with basic features. It
is intended as an option when the Shark® 100
meter’s advanced features are not needed. For
communication, it has an RS485/Pulse Outputs
option (Option 485P). Since it doesn’t have an
IrDA port, Limits, or %THD readings, its faceplate
is slightly different from the images shown of the Shark® 100 meter’s faceplate.
2.1.1: Voltage and Current Inputs
Universal Voltage Inputs
Voltage inputs allow measurement to 416 Volts Line-to-Neutral and 721 Volts Line-to-
Line. This insures proper meter safety when wiring directly to high Voltage systems.
One unit will perform to specification on 69 Volt, 120 Volt, 230 Volt, 277 Volt, 277 Volt
and 347 Volt power systems.
Current Inputs
The Shark® 100/50 meter’s current inputs use a unique dual input method:
Method 1: CT Pass Through
The CT wire passes directly through the meter without any physical termination on
the meter. This insures that the meter cannot be a point of failure on the CT circuit.
This is preferable for utility users when sharing relay class CTs. No Burden is added to
the secondary CT circuit.
