High precision energy meter with LCD display, supports Modbus RTU, and RS485 communication.
The PM3250 power meter from Schneider Electric offers high precision energy monitoring solutions. It is designed for DIN rail mounting and features a clear, backlit LCD display with a resolution of 128 by 96 pixels. The meter ensures Class 0.5S accuracy as per IEC 62053-22 standard, providing reliable data with 32 samples per cycle. This device measures a range of electrical parameters including Energy, Active and Reactive Power, Voltage, Current, Frequency, Power Factor, Apparent Power, and Total Harmonic Distortion up to the 15th Harmonic. It supports operation in networks of 50Hz or 60Hz and can handle supply voltages from 100 to 277VAC, 173 to 480VAC, as well as 100 to 300VDC. The PM3250 accommodates line rated currents of 1A or 5A and is compatible with Single Phase, Single Phase and Neutral, or Three Phase configurations. Direct measurement ranges are 50 to 570VAC, with external VT ranges from 570 to 999000VAC. The device offers robust communication via Modbus RTU and ASCII protocols over RS485, and supports event recording with up to 5 alarms.
