UT285C

Product catalog summary
Overview: The UT285C is a Three Phase Power Quality Analyzer designed for real-time waveform display and comprehensive power quality analysis. It supports multiple voltage and current channels and provides detailed measurements of power parameters.
Specifications:
  • Voltage and Current Measurement: True RMS values for phase-to-neutral and phase-to-phase voltages (1.0V~1000V, 1.0V~2000V) and currents (10mA~1000A). Peak voltage and current values are also measured.
  • Power Measurement: Active, reactive, and apparent power measurements are available, with power factors ranging from -1.000 to 1.000.
  • Harmonic Analysis: Total harmonic distortion (THD) and harmonic ratios for orders 1 to 50 are provided, with phase shift and harmonic angle measurements.
  • Energy Measurement: Active, reactive, and apparent energy measurements are supported, with ranges up to 9999.9MWh, MVARh, and MVAh respectively.
  • Additional Features: Includes short-term voltage flicker (PST), three-phase unbalance, transformer K factor, and phase angle measurements.
Interface and Software: The device includes a USB interface for PC software integration, allowing for data transfer and analysis.
Physical Characteristics:
  • Dimensions: 240mm x 170mm x 68mm
  • Weight: Instrument: 1.6kg, Current clamp: 510g each
  • Power Supply: 9.6V rechargeable lithium-ion battery
Accessories: Comes with a carry cloth bag, test leads, alligator clips, power adapter, CD software, and current clamps.
Accuracy: Various accuracy levels are specified for different measurements, generally within ±(0.5%+5dgt) to ±(1.5%+10dgt).
