24 V DC power supplies

These high-quality 24V switched-mode power supplies excel by their wide range of performance. Flexible one-phase or three-phase primary voltages with wide-range inputs can be used worldwide. Degrees of efficiency of up to 94 percent ensure that the control cabinet only heats up slightly. The units are protected against overvoltage and permanent short circuit.

Electronic circuit breakers

Safety on the 24 V side
As opposed to the 230 V primary side, the circuit protection in the secondary circuit is often neglected. Another issue is that in the event of a failure of the 24 V DC voltage supply standard mechanical circuit breakers often do not trigger. This may happen with long cables, for example.
The electronic fuse from ifm monitors the circuit ideally and, if required, it is reliably switched off. Individual branch circuits can be selectively switched-off. This allows a reduction of wire cross-sections in the load circuit of the switched-mode power supplies.
The system has a modular structure and can be ideally adapted to the circuits of plant and machinery. The IO-Link version also allows evaluation of important diagnostic data.

AS-i power supplies

All AS-i power supplies are primary switched-mode power supplies with a high degree of efficiency. The robust DIN rail housing can be easily integrated in large control cabinets as well as in local boxes. The primary voltage range stretches from 24 V DC via 230 V AC up to 400 V AC three-phase and can consequently be adapted to the local conditions.
