When it may not be suitable

This power supply is not intended for high-power applications exceeding its 60W capacity. It is also not designed for outdoor environments without an appropriate protective enclosure, as it lacks specific ingress protection ratings for direct exposure to moisture or dust.

Key specifications

• Output voltage: 24V DC
• Output current: 2.5A
• Power output: 60W
• Input voltage range: 85-264V AC
• Mounting type: DIN rail
• MTBF: 1,061,000 hours

How to use

Installation involves snapping the unit onto a standard 35mm DIN rail within a ventilated control cabinet. Connect the AC input lines to the designated terminals, ensuring the supply voltage matches the specified input range. The DC output terminals should be wired to the load, observing correct polarity. Ensure that the surrounding area allows for adequate airflow to prevent overheating during continuous operation.

What to consider before purchase

• Verify that the total power consumption of your connected devices does not exceed 60W.
• Ensure the installation environment provides sufficient space for heat dissipation.
• Check that your local AC supply voltage falls within the 85-264V range.

Usage recommendations

For optimal performance and safety, always use appropriately sized wiring and ensure that the power supply is installed in a vertical orientation to facilitate natural convection cooling. Periodically inspect terminal connections to ensure they remain secure.
