Maximum reliability for 24 VDC ciuits in your machinery

The today in the power of control current circle using switch networked to the output current and are with self-protection against over stream equipment. If the nominal value is exceeded, the switching power supply regulates the output voltage and the connected machine part stops. To prevent this, thermal magnetic miniature circuit breakers are generally used. However, you need very high switch-off currents - if these are not reached, the circuit breaker does not respond, and the switching power supply regulates. In addition, the tripping characteristics of the thermo-specific circuit breakers considerably limit the possible cable lengths. Because the impedance of a line that is too long would reduce the overcurrent to such an extent that the circuit breaker no longer detects the fault. Subsequently, the fuse protection must not react to high system-related inrush currents - it must accordingly have intelligent overcurrent detection.

The whitepaper provides information on the various aspects that must be considered when planning the protection of 24V DC control circuits. It shows how electronic circuit breakers can increase the availability of machines and systems and make the design of the protection of control circuits more efficient.

Eaton's circuit protection architecture

The PXS24  is implemented into eatons cuircuit protection architecture for the different circuits of a engergy distribution in a factory and a machine. Control circuits are crusial for any machine. Therfore the protetion of 24 VDC circuit is of high importance.
