Switch-mode power supply with reserve
November 2017, Electrical Power & Protection


ifm’s powerful new switch-mode power supplies provide an excellent power reserve of 50% for up to four seconds to cope with high current loads. Instead of an inrush current limitation with a simple NTC element, charging the capacitors of the new ifm switched-mode power supplies is microprocessor controlled. This allows the selectivity of fuses protecting the inputs on the primary side and saves wiring costs.

The voltage supply is ensured for several milliseconds if the mains voltage briefly fails, e.g. caused by switching operations in the supply network. The supplies provide the specific nominal power across the entire temperature range and derating only has to be taken into account above an operating temperature of 60°C.

All 24 V switched-mode power supplies are equipped with double terminals. This simplifies wiring and provides more clarity in the control cabinet. These supplies are designed for efficiency and reach a higher than average figure of around 95%. This saves energy costs and reduces waste heat in the cabinet. Innovative technology means the new ifm power supplies require considerably less space in the panel, as compared to common cabinet power supplies.
