Power supplies employ selective fuse breaking

14 May 2008 Power Electronics / Power Management

Quint Power compact power supplies from Phoenix Contact are now equipped with selective fuse breaking (SFB) technology. In order to trigger standard circuit breakers magnetically and thus within a few milliseconds, power supplies must temporarily deliver a rated current that is considerably higher than normal; these power supplies now provide this power reserve. The six-fold rated current supplied for 12 ms allows faulty current paths to be selectively shut down while other system components remain in operation without interruption.

The diagnostics of the connected loads have been expanded and constantly monitor output voltage and output power. In addition to normal operation and malfunctions, the preventive monitoring feature now also identifies critical operating states while the power supply continues to operate faultlessly. This allows the controller to recognise faults with connected loads at an early stage, and these faults can be eliminated before they lead to drops in voltage.

One- and three-phase versions with output currents of 3,5, 5, 10 and 20 A are currently available, with output voltage adjustable between 18 and 29,5 V d.c. The power supplies are suitable for worldwide use in all industrial sectors thanks to their wide-range input, extensive international certification and a broad temperature range from -25 to +70°C. The high withstanding voltage of up to 300 V a.c. ensures additional operational reliability. If one phase of the three-phase power supply system fails, the power supply unit will continually supply the full output power.
