Power supply units for medicine and rail transport

From |

Phoenix Contact’s Quint Power series of power supply units addresses new fields of application: The devices can now be employed in electrical medical equipment such as in operating room lighting or hospital beds thanks to the new inspection certificate of single-phase power supplies in compliance with IEC 60601-1 or EN 60601-1.

The four dip-coated modules also offer excellent protection in extreme environments against dust, corrosive gases, or in 100% humidity, and are compliant with the railway directive EN 50155.

The power supply units supply output currents from 3.5 to 40 A at rated output voltages of 12, 24, and 48 V DC. The SFB (Selective Fuse Breaking) technology reliably trips standard circuit breakers, for maximum availability of connected loads.

Faulty current paths are thus selectively turned off, the fault is immediately localized, and important system components remain operational. The 40 A module, for example, supplies a peak current of 215 A for 12 milliseconds to magnetically trip circuit breakers.

The preventive function monitoring of voltage and current visualizes critical operating states and signals them to the control system via the active switching output or the floating relay contact before faults can occur. With the Power Boost power reserve, the 1.5 x rated current is available for starting consumers with high inrush currents reliably, without the rated output voltage dipping.

With an efficiency of up to 93 percent, these devices generate only a low level of undesirable power loss in the form of heat. This not only saves energy but also extends the service life of all components.
