2868622

What type of device is this?

It is a primary-switched STEP POWER power supply unit designed to convert a single-phase AC or compatible DC input into a regulated 24 V DC output.

What is the rated output voltage and current?

The unit provides a nominal output of 24 V DC at 0.75 A, corresponding to 18 W of output power. It can continuously provide 0.83 A at ambient temperatures up to 40 °C.

What input voltage range does the power supply accept?

Phoenix Contact 2868622 accepts an input range of 85 to 264 V AC or 95 to 250 V DC. For AC operation, the supported frequency range is 45 to 65 Hz.

How is the unit mounted?

It can be snapped onto a horizontal 35 mm DIN rail or secured to a flat surface, making it suitable for compact distribution boards and control enclosures.

What are the dimensions of the power supply?

The unit measures 36 mm wide, 90 mm high and 43 mm deep. Its compact housing is intended for installations where enclosure space is limited.

What operating temperature range is supported?

The specified operating range is -25 °C to 70 °C. Above 55 °C, the available output is reduced at a derating rate of 2.5% per kelvin.

Does the unit have an operating-status indicator?

Yes. A green LED provides a visual indication that the operating voltage is present.

What type of electrical connections are used?

The input and output use M3 screw connections. They accept solid or flexible conductors from 0.2 to 2.5 mm², equivalent to AWG 24 to AWG 12, with a recommended stripping length of 6.5 mm.

Can multiple units be connected together?

Yes. The power supplies may be connected in parallel for redundancy or increased capacity, and series connection is also permitted when the application requires it.

How efficient is this power supply?

Efficiency is greater than 84% when operated from a 230 V AC input under nominal conditions. Maximum no-load power dissipation is less than 0.5 W.

What level of environmental protection does the enclosure provide?

The unit has an IP20 degree of protection and is intended for installation inside a suitable closed control cabinet or distribution enclosure.

Does the power supply include input protection?

Yes. It incorporates a 1.25 A slow-blow internal input fuse and varistor-based transient surge protection. Suitable upstream circuit breakers are rated from 6 A to 16 A with B, C, D or K characteristics.

What is the maximum output current?

The specified maximum output current is 1.4 A. The nominal continuous rating remains 0.75 A between -25 °C and 55 °C.

Is the output suitable for low-voltage control equipment?

Yes. Its regulated 24 V DC output is suited to building automation equipment, relays, sensors and other compatible low-voltage control devices, provided their combined electrical demand remains within the unit's ratings.

What is the unit's approximate weight?

Phoenix Contact 2868622 has a net weight of approximately 0.11 kg, excluding packaging.
