<< Revenue Models >>
• Meet the ANSI C12.1-2008 standard for revenue metering when used with class 0.6 or better current transformers.
• Meet the ANSI C12.20-2010 standard for revenue metering when used with class 0.3 or better current transformers.
<< Measurement >>
• Update Rate: 0.1 second. Internally, all measurements are performed at this rate, except the energy registers, which are updated every 1.0 second.
• Start-Up Time: Energy measurement starts ~100 milliseconds after the supply voltage is applied. Modbus communication is enabled ~300 milliseconds after the supply is applied; at this time, all the registers will report valid data, such as power, voltage, current, etc.
• Default CT Phase Angle Correction: 0.0 degrees.

<< General Electrical >>
• Line Frequency: 45 to 65 Hz
• Nominal Line-to-Neutral Vac: 90 to 347 Vac
• Nominal Line-to-Line Vac: 120 to 600 Vac
• Measurement Over-Voltage Limit: 720 Vac
• Over-Current Limit: 200% of rated current. Exceeding 200% of rated current will not harm the meter, but the current and power will not be measured accurately.
• Maximum Surge: EN 61000-4-5: 2kV, ANSI C12.1 combination wave: 6kV, 1.2/50 μs – 8/20 μs
• Line Voltage Power Consumption: The line voltage sensing circuitry draws 0.006 watts per phase at 120 Vac, increasing to 0.150 watts per phase at 600 Vac.
• Real Power (50-60 Hz): <= 0.2 watts
• Power Factor: ~1.0
• Rated VA: 25 VA at 720 Vac, 50 Hz. The Rated VA is the maximum at 115% of nominal Vac at 50 Hz.
• Measurement Category: The line voltage measurement terminals on the meter are rated for CAT III, 600 Vac. Measurement Category III is for measurements performed in the building installation. Examples are measurements on distribution boards, bus-bars, branch circuits, plug loads, and permanently connected equipment such as motors, boilers and heaters.
