LEM CV3-1500 Voltage Transducer

The LEM CV3-1500 is a high-precision, closed-loop voltage transducer designed for accurate measurement of DC, AC, and pulsed voltages in industrial applications. It features galvanic isolation between primary and secondary circuits, ensuring safety and reliability in high-voltage environments. Key benefits include excellent linearity, low offset drift, and fast response time, making it ideal for traction, power supplies, motor drives, and renewable energy systems. Compared to similar products like those from ABB or Honeywell, the CV3-1500 offers superior bandwidth (up to 300 kHz) and accuracy (±0.2%), with drawbacks including a higher cost and the need for external power supply. It supports a primary nominal RMS voltage of 1500 V, with an analog output of ±10 V, and is suitable for harsh industrial conditions with operating temperatures from -40°C to +85°C. The compact design with DIN rail mounting facilitates easy integration. Based on attached images, the unit appears new or refurbished in excellent condition, with visible labels indicating specifications like 1000Vrms isolation, 10V/1500V output scaling, and 6kV RMS 60s withstand voltage. No parent/child assets are evident. Estimated market price for a used unit in this condition is $150-300 USD, based on recent eBay and industrial surplus listings.
