Quint Power power supply unit - Power supply always and everywhere

The reliability of a power supply unit determines the availability of the individual components of a system and whether complex systems function reliably. At the same time, the globalization of the markets increases the requirements for a power supply unit. A wide-range input and high availability are becoming necessary in unstable networks as well. The requirements are met by the world power supply unit Quint Power in the second generation.

The wide-range input of the power supply unit of 3 x 320-575 V AC ensures operation with all conventional voltages in the world. Thus, the devices can be operated on the 380/400 and 480 V AC network without faulty switching over. This saves storage costs and reduces the logistical work. Quint Power also functions in applications where static voltage dips, transient failures of the supply voltage or continuous phase failure are to be expected.

In the case of electrical equipment, line protection is ensured through a shared overcurrent protection device, frequently in the form of a circuit breaker. If a single-phase consumer short-circuits, the circuit breaker isolates the faulty path. The three-phase power supply is then inevitably supplied with only two phases. While a standard power supply unit provides an undefined output voltage here, Quint Power continuously provide the full output power even when a phase fails.

Reliable operation with two phases is ensured by intermediate circuit capacitors with a capacity four times higher than that of comparable standard power supply units. The high mains buffering of more than 20 ms under full load is a positive effect of this energy storing device. This reserve is available to reliably bridge the switchover of faulty supply networks with voltage dips of typically 10 ms. The demands on the stable and regulated output voltage are as high as the requirements on the input circuit of the power supply. Many primary switched-mode regulators are unable to cope with connecting loads with high inrush currents (splutter). The U/I characteristic curve represents a practical solution as proven with all Quint Power power supply units from 10 A.

In the second generation, the 20 A device has a power reserve of 35% - the Power Boost, the most efficient remedy against splutter. Moreover, at temperatures as high as +40°C, consumers can be permanently supplied with 27 A at 24 V DC. If the output current increases further, the output voltage is automatically reduced and the connected electronics are reliably protected. As soon as the set voltage sinks by more than 10%, the function LED will flash. For remote monitoring, an active transistor switching output and a floating relay contact are available. The active output can carry up to 88 mA and can easily be integrated in any conventional control system with 24 V DC inputs. The relay output can switch currents up to 1 A at 30 V DC and is used wherever a floating signal is required.
