## Long description

The Phoenix Contact STEP3-PS/1AC/24DC/0.63/PT is a compact 24 V DC power supply delivering up to 0.63 A and a total output power of 15 W. Designed for control cabinets and industrial automation installations, it accepts a wide AC input range of 100–250 V at 50–60 Hz and provides a stable low-voltage DC output. The unit’s small form factor (18 mm x 61 mm x 90 mm) allows space-saving mounting on DIN rails while meeting RoHS and WEEE environmental requirements. Rated with a high mean time between failures (MTBF) of 3,500,000 hours, it is intended for continuous operation in demanding environments.
Advantages
The power supply offers consistent voltage regulation and overcurrent protection suitable for sensitive electronics. Its narrow 18 mm housing conserves panel space in crowded control cabinets. Wide input voltage compatibility simplifies installation in locations with variable mains conditions. Compliance with RoHS and WEEE indicates reduced hazardous substances and end-of-life handling considerations. The high MTBF figure reflects durable components and predictable long-term performance.
Suitable for
DIN-rail mounted control cabinets and industrial enclosures
Small PLCs, I/O modules and fieldbus devices requiring 24 V DC
Backup circuits, signal conditioning modules and sensor power
Machine control panels where space is limited

How to use
Mount the unit on a standard DIN rail inside the control cabinet, ensuring adequate clearance for ventilation. Connect the AC mains to the input terminals observing proper phase and protective earth connections, and tighten terminal screws to the manufacturer’s torque specifications. Connect the 24 V DC outputs to the load side, verifying polarity and combined current draw does not exceed 0.63 A. Allow a short start-up time for the output to stabilize before applying sensitive electronics. Follow local electrical codes and power down the mains before wiring.
Usage recommendations
For reliable long-term operation, install the power supply in a ventilated enclosure away from direct heat sources, observe the rated ambient temperature and load limits, and use appropriate short-circuit protection on the DC side. Periodically inspect terminals for secure connections and ensure the surrounding area remains free of dust and conductive debris.
