T250 Series DIN-Rail Power Meter | T250-MD01 | RS-485 | 96×96 Panel Mount

Comprehensive Power Monitoring in a Compact Format

The T250 is a versatile, precision-class multifunction power meter built for real-time energy measurement in modern commercial and industrial environments. Designed for switchboards, subpanels, and energy management systems (EMS/BMS), the T250 provides true RMS readings with Class 0.5S accuracy and advanced harmonic analysis up to the 31st order.

Supporting a range of input configurations (1P2W, 3P3W, 3P4W), the T250 offers key insights into power quality, demand patterns, and system efficiency, all from a compact DIN 96 × 96 mm panel-mount housing. The high-visibility backlit LCD display includes bargraph current indicators and intuitive navigation for field teams and facility engineers.

Standard Modbus RTU (RS-485) communication ensures seamless integration with automation, SCADA, and BMS platforms. Optional modules for relay outputs, analog signals, or digital inputs allow flexible system expansion based on project needs.

Ideal for EMS/BMS integration, THD tracking, and energy optimization.
