Parameters Parameter Specification Product Series PowerLogic PM800 Series Device Type Multi-function Power Meter Commercial Reference PM8M26 Measurement Inputs Voltage: 3-phase + Neutral (direct connection or via PT). Current: 3 current inputs (via external Current Transformers - CTs). System Compatibility Three-phase 3-wire or 4-wire systems. Key Measurements • Volts, Amps, Frequency, Power Factor • Active, Reactive, Apparent Power (kW, kVAR, kVA) • Active & Reactive Energy (kWh, kVARh import/export) • Demand (sliding window) • Basic Power Quality: Voltage & current THD (total harmonic distortion). Accuracy Class Active Energy: Class 0.5S per IEC 62053-22 Voltage/Current: Typically 0.2% of reading. Display Optional backlit LCD display module (may be ordered separately). Communication Ports • 1x RS-485 port (supports Modbus RTU). • Optional communication modules available for other protocols (e.g., Ethernet, BACnet). Digital I/O Configurable digital inputs (for status, pulse counting) and relay outputs (for alarms, control) are typically available as options. Power Supply Wide range: 85-265 V AC/DC (self-powered from measured voltage or auxiliary supply). Mounting DIN-rail mounting (35 mm). Operating Temperature -25°C to +70°C. Storage Temperature -40°C to +85°C. Standards & Certifications CE, UL, cUL, IEC 62053-22, RoHS.
