LEM CASR 25-NP Current Transducer, CASR Series, 25A, -85A to 85A, 0.8 %, Voltage Output, 4.75 Vdc to 5.25 Vdc

The CASR series Current Transducer with insulated highly accurate measurements from 1.5 to 50Arms. It has been specially designed to respond to the technology advances in drives and inverters in industrial environment requiring better performances. The closed loop fluxgate technology of current transducer measures current over wide frequency ranges including DC. It provides contact-free coupling to the current that needs to be measured as well as safe galvanic isolation and high reliability. Its output signal is an accurate, high-resolution image of the primary current with a very short delay. In higher frequency ranges this transducer functions exactly the same way as current transformers, where a relatively small induced voltage in the secondary winding is capable to drive the secondary current through the secondary winding and most important, through the burden resistor. A low induced voltage equals low magnetic flux in the magnetic core, which is the cause for the good accuracy.

• 30% smaller in height than LTS transducer
• Construction uses 3 U-shaped primary terminals integrated into the housing
• Great flexibility to perfectly adapt the measuring range
• Good accuracy especially in temperature
• Reduced size
• High immunity against high voltage variations
• High flexibility
• Resistant in rough environmental conditions of use in high humidity combined with high temperature
• Common mode influence
• Thermal drift (offset and gain)
