CASR 50-NP Description

Short technical summary and product information.

The LEM CASR 50-NP is a compact, closed-loop fluxgate current sensor designed for accurate measurement of DC, AC, and pulsed currents. It operates with a single +5V supply and is intended for PCB mounting.

 

Key electrical specifications include a nominal current rating of 50A RMS, ±0.8% accuracy, and ±1% linearity. The sensor provides a ratiometric voltage output with a sensitivity of 12.5mV/A. It features a fast response time of less than 0.3µs and a wide bandwidth up to 300kHz (+/- 3dB).

 

This sensor is suitable for a variety of industrial applications requiring precise current measurement and galvanic isolation. Its closed-loop Fluxgate technology ensures excellent accuracy, very low offset, and stable performance over a wide operating range. The addition of a reference pin enhances flexibility for signal conditioning and system-level calibration.

 

The CASR 50-NP is housed in an insulating plastic case and is designed for through-hole mounting. It operates within a temperature range of -40°C to 85°C.
