NOTE:
Additional error of 0.05 % of full scale for input current below 100 mA.
PF error limit is same as W error limit in %.
Auxiliary supply (Control power)
The power meter needs a single-phase AC or DC control supply to power its
internal electronics.
Range: 44 to 277 VAC/DC.
Burden (load): 0.2 VA max for each phase input voltage and current 3 VA
max on Auxiliary supply.
Front Panel Display
Brilliant three lines four digit (digit height 14.2 mm/0.56 in.) per line, high
readability alpha numeric LED display with auto scaling capability for Kilo,
Mega, Giga.
The display provides the user access to all phase voltages (phase to
neutral and phase to phase), currents (per phase and average), Watts,
VARs, VA, power factor, frequency, kWh, kVAh, and kVARh.
The power meters display average volts, amps, and frequency
simultaneously.
Load bar graph for the indication of consumption in terms of % amperes
total.
Set of four red LED’s in the load bar start blinking when the load is greater
than 120%, to indicate overload.
Easy setup through keys located on the faceplate for common
configuration parameters.
