PN800 Energy Meter
The Series PN800 Multi Function Digital Power Analyzer designed for Energy Metering and Power Monitoring in electrical distribution systems. It’s a key component for improving energy efficiency and understanding electrical network characteristics.
It measures and displays a wide range of electrical parameters for single-phase and three-phase networks, including voltage, current, power (active, reactive, apparent), energy (kWh), power factor, and frequency.
It complies with IEC 62053-22 Class 0.5s for active energy, ensuring precise measurements. Large backlit LCD display provides clear and direct readings of multiple measurement and metering values, making it easy to use. RS485 Modbus communication enables remote monitoring and integration into building management systems (BMS) or SCADA systems.
PN800 includes digital inputs for reading pulses from other devices (e.g., water or gas meters) and digital outputs for control / command or alarm signaling. THD (Total Harmonic Distortion) calculation measures voltage and current harmonics up to the 63rd order, which is crucial for power quality analysis.
