Industrial & Commercial Power Monitoring

Energy & Power Metering

Undetected inefficiencies, poor power factor, and load imbalances cost industrial and commercial facilities every single day. The EN 8400 / PN 8700 series of multifunction energy meters, ETL and UL Listed, delivers Class 0.2s measurement accuracy, harmonic analysis up to the 63rd order, and seamless Modbus/Ethernet connectivity so engineers, facility managers, and energy teams can monitor the health of their power systems effectively and act on real data.

Smarter Energy Management Starts Here

0.2s Measurement Accuracy

The PN 8700 Pro achieves Class 0.2s per IEC 62053-22 — revenue-grade precision suitable for energy audits, ISO 50001 reporting, and utility-grade sub-metering applications.

Harmonics Up to 63rd Order

Monitor voltage and current THD with individual harmonic analysis up to the 63rd order at 512 samples per cycle — identify non-linear load problems before they damage equipment.

Data Logging & Cloud Connectivity

256MB onboard storage with USB download plus MQTT-enabled cloud push keeps your energy data continuously logged, accessible, and ready for analysis.

Demand Forecasting & TOD

Track rising demand, forecast VA/W/VAR in real time, and manage Time of Day energy across up to 8 programmable slots to reduce peak demand charges.

Flexible I/O & System Integration

Dual RS485 + Ethernet ports with simultaneous polling, plus optional digital and analog I/O, make the PN 8700 series compatible with any PLC, SCADA, DCS, or BMS platform.

The EN 8400 / PN 8700 series are high-profile multifunction meters designed to give industrial and commercial customers complete real-time visibility into their electrical systems, including:

Voltage & Current (per phase and 3-phase totals)
Active, Reactive & Apparent Power and Power Factor
THD and Individual Harmonics up to 63rd order
kWh, kVAh, kVARh Import & Export with phasewise tracking
Voltage Sag, Swell & Interruption Events
Demand, Forecast Demand, TOD Energy & 12AM/31st Day Snapshots
CO₂ Emission, ON Hours & Power Interruptions

By continuously logging these parameters, the EN/PN series reveals energy patterns and system health issues that spot checks and basic meters will always miss.

Main Incomer & Sub-Metering Panels:
Capture total facility energy and demand profile at the source for tenant billing and ISO 50001 compliance.

Motor Control Centers (MCC):
Monitor current unbalance, overload, and power factor deviation to protect motors before failure occurs.

Manufacturing & Process Control:
Integrate via Modbus RTU or Ethernet TCP into PLC, SCADA, and DCS workflows for live energy data in process dashboards.

HVAC & Building Automation:
Track energy consumption of large HVAC loads and shift TOD demand to minimize utility charges.

Data Centers & Critical Infrastructure:
Log UPS output quality, generator transfer events, and distribution panel loads with full Dip/Swell event capture.
