ELECTRIC.IE • The Magazine & Website for the Irish Electrical Industry • 15 Phoenix Contact Powerful DC/DC converters The new generation of DC/ DC converters from Phoenix Contact’s Quint product family offers more than just regulated DC voltage. The devices combine the functions of a DC/DC converter with the product features of the Quint Power power supply. It is the only product of its kind on the market. The new Quint DC/DC converters have a dynamic power reserve. For starting heavy loads, the dynamic boost offers twice the output power for 5 s. The SFB Technology (Selective Fuse Breaking Technology) delivers 6x the nominal current for 15 ms, which is enough power to reliably and economically protect DC circuits. Standard miniature circuit breakers are selectively tripped while consumers connected in parallel continue working. The static boost with up to 125% continuous power makes it easy to expand the system. Furthermore, the comprehensive signaling with analog, digital, and relay contacts allows for preventive function monitoring of the system. Possible changes during operation are detected early on and errors are effectively prevented. The choice between Push-in and screw connection technology is another new feature. Moreover, the IECEx approval enables use in potentially explosive areas. Thanks to the wide temperature range of -25°C to +70°C, the devices are flexible in application and will even start at an ambient temperature of -40°C. The NFC interface can be used to individually adapt signaling thresholds and characteristic curves. The most powerful power supply on the market The new Quint Power power supplies with 40 A output current from Phoenix Contact are the most powerful power supplies on the market and feature innovative new functions: the single-phase device with a multi-stage PFC on the input side optimizes the degree of efficiency across the entire power range to achieve a long service life. The three-phase device does not generate any inrush current, thus preventing unintended tripping of the backup fuse after a short mains interruption. Just like the rest of the QUINT POWER product range, the 40 A devices impress with their powerful output side, robust input side, and comprehensive signaling. The output side of the power supplies ensures high system availability. The static boost, which provides up to 125% of the nominal current for a sustained period, enables easy system extension. There is also the dynamic boost to start heavy loads with up to twice the nominal current for up to five seconds. SFB (Selective Fuse Breaking) Technology provides six times the nominal current for up to 15 ms and therefore trips standard circuit breakers selectively. Consumers connected in parallel continue working. The input side, featuring an integrated gas discharge tube, ensures a high degree of immunity up to 6 kV and a mains failure buffer time of at least 20 ms. The comprehensive signaling with analog, digital, and relay contacts enables preventive function monitoring. Critical operating states are reported before errors occur. The Quint Power power supply can be ordered preconfigured starting from a minimum quantity of one unit. Signaling thresholds and characteristic curves can be individually adjusted. The wide temperature range from -40°C to +70°C means that the devices can be used flexibly even in areas subject to extreme environmental conditions.
