symbolizing trust and the beginning of a long-term partnership

A Three Phase Power Quality Analyzer measures voltage, current, active/reactive/apparent power, power factor, frequency, and active/reactive energy. It also monitors harmonics (2nd–63rd), total harmonic distortion (THD), crest factor, K factor, voltage/current imbalance, flicker, voltage surges, dips, and short interruptions, providing a full overview of system power quality.

This analyzer offers Class 0.2 accuracy for voltage and current, 0.2S for active energy, ±2% for reactive energy, and ±0.002Hz for frequency. High accuracy ensures precise billing, reliable energy monitoring, and early detection of abnormal conditions, which is critical for industrial plants, AI infrastructure, and data centers where stable power is essential.

Yes. It supports RS485 with Modbus-RTU (1200–38400bps) and optional Profibus-DP (9600–12Mbps), allowing seamless integration into SCADA, EMS, or building energy management systems. Digital inputs, relay outputs, and pulse outputs further support automation and control applications.

By continuously monitoring load, power factor, harmonics, and demand, the analyzer identifies inefficient energy usage and abnormal power events. Multi-rate measurement and historical data tracking allow operators to optimize tariffs, schedule loads, and plan preventive maintenance, ultimately reducing operational costs.

Yes. It operates under -25°C to +70°C, up to 95% humidity (non-condensing), and altitudes below 4000m. The front panel is IP54 rated, and the device is designed to withstand surges, fast transients, electrostatic discharge, and power frequency magnetic fields (IEC61000-4 series Level 4). This makes it reliable for chemical plants, steel mills, and data centers.

AI data centers require stable, high-quality power for critical servers and computing clusters. This analyzer provides real-time monitoring of voltage sags, swells, harmonics, and imbalances, allowing early detection of disturbances. With historical data, multi-tariff energy monitoring, and precise fault records, operators can maintain high uptime, improve energy efficiency, and protect sensitive equipment.
