Apart from the space-saving housing, the new 24 V power supply family from ifm electronic is distinguished by a high degree of efficiency. Depending on the version, output current ranges from 3,3 to 20 A. In addition, the units possess high power reserves and reliably switch off the circuit breaker in case of a short circuit.
Thanks to innovative technologies, the new power supplies require considerably less space in the control cabinet. Another advantage is the above average efficiency of up to 94%. This reduces waste heat and saves energy costs. Instead of using an NTC resistor, a microcontroller keeps the inrush current low, making it easier to protect the wiring.
The positioning of the components allows permanent operation even at the limits of the specification. This results in excellent MTBF values ranging from 0,89 to 1,4 million hours. All power supplies offer sufficient reserves to deal with load current peaks while the voltage supply is ensured for several milliseconds in case of short failures of the mains voltage. For the optimisation of AS-i technology, ifm electronic also offers newly developed switched mode power supplies for the range between 2,8 and 8 A.For more information contact Alwyn Skelton, ifm electronic SA, 086 143 6772, [email protected], www.ifm.com/za
