Phoenix Contact now offers an especially compact Mini Power adaptor with 24 V (DC) and 1.5 A for use in Ex areas. It is compliant with the EN 60079-15 standard and may be used in hazardous areas where 3 G category materials are required. Thanks to a wide input range of 85 to 264 V (AC) and an international certification package, this power adaptor can be used anywhere in the world. A power failure bridging time of more than 100 ms under full load and the high Mean Time Between Failure (MTBF) of greater than 500,000 h provide a high degree of operational reliability even in unstable networks. With the Power Boost power reserve, the devices supply 2 A of output current. This current is permanent in ambient temperatures up to 40 °C or available for a few minutes in higher temperatures. The output current is limited to 2 A in the event of a secondary short-circuit or overload. If this happens, the module does not shut off but continues to supply the output current, and the secondary voltage is reduced until the short-circuit is fixed. The V/I characteristic with Power Boost reserve ensures a reliable supply of high start-up currents of capacitive loads or from consumers with DC/DC converters in the input circuit.
