Description
The Phoenix Contact STEP POWER 2868583 is a compact, primary-switched AC/DC DIN rail power supply designed to provide reliable 12V DC power at 5A for building automation, industrial control, and electrical distribution applications.
The unit delivers 60W of nominal output power and accepts a wide 85–264V AC input range, with a nominal input range of 100–240V AC. It can also operate from a 95–250V DC input, providing additional flexibility for industrial power systems.
The output voltage is adjustable from 10V to 16.5V DC, while the nominal output current is 5A. Under suitable temperature conditions, the unit can provide up to 5.5A continuously. Electronic secondary-side fuse protection and output overvoltage protection help safeguard connected equipment.
Its STEP POWER design focuses on energy efficiency, with low no-load power consumption and typical efficiency above 87% at 230V AC under nominal conditions. A green DC OK LED provides convenient visual confirmation of output status.
The power supply can be snapped onto a standard NS 35 DIN rail or mounted directly onto a suitable surface. Its compact housing measures approximately 72 × 90 × 55 mm, making it suitable for installations where cabinet space is important.
