Phoenix Contact STEP-PS/1AC/24DC/0.75 Power Supply

In this review of the Phoenix Contact STEP-PS/1AC/24DC/0.75 power supply, the reviewer finds it to be a compact, reliable DIN-rail unit suited to small control cabinets and low-power industrial I/O. The bottom line: this is a straightforward 24Vdc, 0.75A module that excels where space and simplicity matter. For engineers or technicians needing a clean replacement or a compact feed for sensors and relays, the unit's small footprint and new condition make it a practical choice. The review focuses on real-world fit, installation footprint, and steady output behavior.

Key Features

• Compact size: The 5.00 in x 3.00 in x 3.00 in dimensions make it easy to mount in tight control cabinets and on DIN rails without crowding neighboring components.
• 24Vdc output: The regulated 24 volt DC output is suitable for common industrial sensors, relays, and PLC inputs that require a stable low-current supply.
• 0.75A capacity: The 0.75 amp rating provides a reliable power budget for small I/O clusters or single-device applications without excessive overspecification.
• New condition: Arriving new ensures full expected lifetime performance and avoids the wear concerns that can accompany used power modules.
• Single-phase input: Designed for single-phase mains, it integrates easily into standard control panels where three-phase distribution is not required.

Who It's For

The STEP-PS/1AC/24DC/0.75 is aimed at maintenance technicians, panel builders, and automation hobbyists who need a small, dependable 24V DC source for sensors, small relay banks, or PLC I/O modules. Its compact size and straightforward ratings make it particularly useful in retrofit projects or in distributed control cabinets where space is at a premium.

Those who need higher current, redundant supplies, or built-in advanced protections should look elsewhere; this unit is best used as a simple, single-output supply for light loads rather than as a high-availability power backbone.

Pros & Cons

Pros

• Small physical footprint makes panel layout easier in cramped installations.
• 24Vdc regulated output suits many industrial control components and sensors.
• New condition from manufacturer reduces risk of early-life failures.

Cons

• 0.75A output is limited to low-power applications and cannot support larger actuator loads.

Specifications

Our Verdict

The Phoenix Contact STEP-PS/1AC/24DC/0.75 is a no-nonsense, compact 24V supply that represents good value for small automation projects. Buy it if you need a tidy, reliable power source for sensors or low-current I/O; skip it if your application needs higher current or redundant power arrangements.

Frequently Asked Questions

Is this unit suitable for DIN-rail mounting?
Yes, the compact dimensions and form factor are intended for mounting on standard DIN rails in control cabinets.

Can it power multiple sensors and relays?
It can power several low-current sensors and relays within the 0.75A budget, but calculate total load to avoid overdraw.

Does it include surge or redundancy features?
No, this model is a simple single-output supply without built-in redundancy; larger systems should use dedicated redundancy modules.
