Series Power Meters Block EM640033

The EM6400 series power meter displays:
1. Voltage: Three voltage measurements line-to-line: 1-2, 2-3, 3-1, and average, Three voltage measurements line-to-neutral: 1-4, 2-4, 3-4, and average.
2. Current: Three current measurements phase-wise (1, 2, 3), average current of all three phases, neutral current, and three current phase angles (A° 1, A° 2, A° 3) with respect to the corresponding voltage line-neutral vector.
3. Phase wise load in %: Three currents in % of the FS (%A FS).
4. Unbalanced load in %: Current and voltage unbalance.
5. Frequency: Measures from whichever phase is active.
6. RPM: Measures the speed of the generator.
7. Power: VA, W, VAR, per phase and total. PF per phase and average. PerPhase W readings provide a quick CT Polarity Check. A negated W phase reading indicates CT reversal.
8. Energy: VAh, Wh, +VARh (Ind), -VARh (Cap), Run hours, On Hrs, supply interruptions (outage).
9. Energy (OLD): VAh, Wh, +VARh (Ind), -VARh (Cap), Run hours.
10. % Amperes load bar graph: Load bar graph indicates consumption in terms of % amperes totawl. You can quickly estimate the load by viewing the display without operating any keys. The bar graph consists of 12 segments. Each segment indicates a current load of 10% of CT primary.
11. Kilo, Mega, Giga indication for the above parameters. See “The Indicators” on page 9 for more information.

Technical Specifications
The EM6400 series power meters are high-accuracy, low cost, ultra compact, power, and energy meter. It offers ISO 9001 quality, accuracy, and functional flexibility. Selective models of this series have Modbus RTU communications capability. The standard unit flush-mounts in a DIN 96 cutout and conforms to UL product standards. The power meters are designed for retrofit applications such as replacement of analog meters. Each can be used as a standalone meter in electrical control panels, power distribution units (PDU), switch boards, uninterrupted power supplies (UPS), generator sets, and motor control center (MCC) systems. It also provides easy communication to program logic controls (PLC), distributed control systems (DCS), building management systems (BMS), and other systems.
