ESE Power-Quality Monitor（Digital Energy）
ESE Series
Comprehensive power-quality monitoring including harmonics, voltage deviation, frequency deviation and three-phase unbalance, for efficiency analysis.
Product Overview
Product Overview The ESE Power Quality Monitor is dedicated to low-voltage three-phase circuits, monitoring voltage, current, power, power factor, phase angle, three-phase unbalance and 2nd-31st harmonics in real time. Voltage/current accuracy Class 0.5, with DO alarm outputs for overvoltage, overcurrent, phase loss and DI linkage. DIN rail mounting; RS485 (Modbus) communication can connect to gateways for cloud upload, forming a power monitoring network. Suitable for full electrical parameter metering, statistics and analysis in distribution cabinets. Class 0.5 accuracy | 260+ electrical parameters | 2nd-31st harmonics | RS485 cloud upload
