Product Description
The PM31 three-phase power meter from Esensors is a high accuracy, three-phase electrical energy meter with a cost effective design to meet your power metering requirements. The device supports active, reactive, and apparent energy measurements in various three-phase configurations, such as wye or delta services, with both three and four wires. With integrated Wi-Fi/ wired LAN options, the PM31 transmits data through the Ethernet using a built-in TCP/IP stack. Data is measured continuously and can be viewed using a built-in web interface. Data can also be polled using network monitoring software (eg. Nagios) that may be configured with preset thresholds to setup email alerts.
- Highly accurate; Based on High speed wave sampling, and a dedicated DSP.
- Compatible with 3-phase, 3- or 4-wire (delta or wye), and other 3-phase services
- Supplies total (fundamental and harmonic) active, reactive and apparent energy, and fundamental active/reactive energy on each phase and on the overall system
- Less than 0.1% error in voltage and current rms over a dynamic range of 1000 to 1 at TA = 25°C
- Less than 0.1% error in active and reactive energy over a dynamic range of 1000 to 1 at TA = 25°C
- Less than 0.2% error in active and reactive energy over a dynamic range of 3000 to 1 at TA = 25°C
- Supports current transformer and di/dt current sensors
- 3 voltage channels and 4 current channels.
