This is a Wattnode brand kilowatt hour (kWh) energy and power meter for 1, 2, or 3 phases with voltages from 120 to 138 volts Vac and currents from 5 to 6,000 amps in delta (phase to phase) and wye (phase to neutral) configurations. The RS485 network communicates over modbus protocol for easy integration with building automation systems.
Wattnode part number: WNC-3Y-208-MB
The Single Phase Power Meter with internal CT are solid state transducers for measuring the current and voltage in fans, pumps, and other HVAC equipment. The current sensors exists in two different types:SPM1-AC, SPM1-DC.The connections are by Modbus.
The 330mv AC series of split core current sensors are ideal for installation on existing electrical wiring by snapping around the conductor without requiring and rewiring or interruption of the existing power cabling. UL listed product.
The split core current transformer are ideal where space is limited, such as when metering multiple loads within a panel board. Use for current measurement, energy metering, load surveys, demand metering, energy research, and submetering applications.
The PM-3P Power Meter is to measure any range of AC/DC voltage or current set by user. It can be available for data reserve or top value reserve function. To measure or display true value of voltage/ampere/watt/power factor/frequency/energy consumption.Up to 3 alarm output.
