Description of CSNK500M-600

The CSNK500M is a closed-loop current transducer based on the principle of magnetic compensation (Hall effect). It is designed for the electronic measurement of DC, AC, or pulsed currents, providing galvanic isolation between the primary (high-power) and secondary (measurement) circuits. The sensor outputs a proportional secondary current of 100mA at the nominal primary current of 500A, allowing for accurate and linear current monitoring.

FAQ

What is the difference between the CSNK500M and CSNK500M-600 listed in the request?
A: The provided datasheet is for the standard CSNK500M model. The specifications for a "CSNK500M-600" variant are not included in this document. The suffix "-600" may indicate a specific version or an extended measurement range, so it is necessary to consult the correct datasheet for its exact specifications.

How does the supply voltage affect the sensor's measuring range?
A: The measuring range of the sensor is influenced by the supply voltage and the measuring resistance (load). A higher supply voltage (±18V vs. ±15V) allows for a larger measuring resistance at the same current, or the ability to measure a higher peak current. For example, to measure a peak current of ±1275 A, a ±18V supply is required with a maximum burden resistance of only 5 ohms. Exceeding these limits will saturate the output.
