APM810 is a 0.2S-class three-phase AC multifunction panel meter engineered for precise energy monitoring, power-quality diagnostics and tenant sub-billing in industrial, commercial and data-center switchboards. The compact 96×96 mm DIN enclosure hosts a color TFT touchscreen that displays true RMS voltage to 690 V, current, frequency, active/reactive/apparent power, PF, demand, harmonics to 63rd, THD and four-quadrant kWh/kvarh. Dual RS485 Modbus-RTU, Ethernet TCP/IP, BACnet/IP, SNMP and optional Wi-Fi/LoRa deliver seamless BMS/EMS integration, while 4 MB onboard memory logs 12-month load profiles for energy audits. Configurable over/under voltage, current, PF and harmonic alarms drive relay outputs or digital inputs for smart breaker control; pulse, SOE and tariff TOU registers support utility AMI, solar net-metering and EV charging applications. Wide 3×57.7–690 V, 0.001–10 A direct or CT/VT connection plus tamper-proof sealing fit any smart-grid or micro-grid deployment.
