Due to innovative technology, the new ifm power supplies require considerably less space in the control cabinet. Another advantage is the degree of efficiency, up to 94%, which saves energy costs and reduces waste heat.
During development, particular importance was attached to sufficient dimensioning of the components to ensure reliable operation even at the limit areas of the specification. This results in an MTBF of approximately 1,4 million hours with sufficient power reserves to reliably handle short current demand spikes.
Instead of an inrush current limitation with a simple NTC, charging of the capacitors of the new switched mode power supplies is microprocessor controlled. This ensures an ideal start-up of the supply and eliminates instabilities associated with short disruptions in the mains supply.
With a wide operating temperature range, the switched-mode power supplies provide the specific nominal power across the entire temperature range and derating only has to be considered above an ambient operating temperature of 60°C. All 24 V switched-mode supplies are equipped with double terminals to simplify wiring and provide more clarity in the control cabinet.
