Power Supply Unit Phoenix Contact STEP3-PS/1AC/24DC/4/PT 96 W AC 100-250 V

The Phoenix Contact STEP3-PS/1AC/24DC/4/PT 96 W AC 100-250 V is a compact industrial power supply designed to deliver a stable 24 V DC output with a rated total power of 96 W. It accepts a wide AC input range of 100–250 V at 50–60 Hz and is built for continuous operation with a high MTBF value, making it suitable for machine control, automation panels and DIN-rail installations where space and reliability are important.

Advantages

This power supply provides a wide input voltage tolerance and frequency compatibility for international use. Its compact enclosure allows installation in space-constrained control cabinets. The unit is designed for long service life and reliable operation as indicated by a high mean time between failures. Compliance with RoHS and WEEE standards reduces environmental impact and simplifies disposal and recycling processes.

Suitable for

• Industrial control cabinets and DIN-rail mounted control systems
• Automation equipment and PLC power supply
• Machine tool electronics and factory floor devices
• Remote panels, sensors and field devices requiring 24 V DC supply

Key specifications

• Output voltage: 24 V DC
• Total output power: 96 W
• Input voltage range: 100–250 V AC
• Input frequency: 50–60 Hz
• MTBF: 1,350,000 hours (mean time between failures)
• Protection and environmental compliance: RoHS and WEEE

How to use

Mount the unit on a standard DIN rail inside an appropriate electrical enclosure. Connect the AC supply to the input terminals following local wiring regulations and ensure correct fusing and grounding. Connect the 24 V DC output to the load, observing polarity and cumulative current limits so the total load does not exceed 96 W. Allow adequate ventilation around the unit and verify the LED or status indicator for normal operation.

Recommendations

Install the power supply in a dust-free, vibration-minimized location inside a control cabinet. Use appropriate surge protection on the AC input for installations exposed to electrical disturbances. Periodically inspect terminal connections for tightness and check ambient temperature to prevent overheating and ensure rated output performance.
