Power Supplies for High System Availability
The system availability can be significantly increased using the new three-phase Quint Power SFB 24 V / 40 A power supplies from Phoenix Contact: using the SFB technology with 200 A for 12 ms (selective fuse breaking technology), standard miniature circuit breakers with B characteristics reliably trip up to 25 A.
Faulted circuits are selectively shut down, the fault is localized, and important system components remain operational. The preventive function monitoring system reports critical operating states before faults actually occur.
The Trio Power UPS 24 V / 5 A uninterruptible power supply offers a function package that has been specifically designed to supply industrial PCs: when the AC line supply fails, the IPC continues to operate without interruption for up to three hours. For longer interruptions, the PC mode ensures that a control automatically restarts when the power supply voltage returns. This saves time when compared to a manual restart. The power supply and the electronic switchover unit are housed in the same enclosure in an especially space-saving design. Buffer times can be individually configured by combining the unit with four rechargeable battery modules.
The Mini Power UPS uninterruptible power supply with 4 A / 12 V DC for input voltages from 85 to 264 V AC or 100 to 350 V DC opens up new application areas. When the AC input voltage fails, the UPS switches over from the power supply to the external rechargeable battery module without any interruption, and all the connected loads are supplied with 12 V DC. Battery modules of either 1.6 or 2.6 Ah, which permits buffer times of up to 30 minutes, can be connected. The comprehensive signaling functionality ensures fast and simple diagnostics.
Step Power supplies achieve a high level of energy efficiency within their class. With the 5 V / 6.5 A, 15 V / 4 A and 48 V / 2 A modules, this advantage now also applies for new applications in the area of building automation. These devices can be snapped onto mounting rails or screwed to flat surfaces and offer a wide temperature range extending from -25 to +70°C.
