Suitable for

• Industrial control panels and automation systems
• Security and surveillance equipment
• Network switches and communication hardware
• LED lighting control systems
• General-purpose DC power requirements in DIN-rail installations

This power supply may not be suitable for applications requiring high peak currents that exceed the 2 A rating or for environments with extreme ambient temperatures that exceed the manufacturer's specified operating range. It is also not intended for outdoor use unless housed in a suitable weather-resistant enclosure.

Key specifications

• Output voltage: 48 V DC
• Output current: 2 A
• Mounting type: DIN-rail
• Cooling method: Natural convection
• Protection: Short-circuit and overload protection

To install the RING MDR-100-48, securely snap the unit onto a standard DIN-rail within your control cabinet. Ensure that the input voltage matches the device requirements before connecting the AC power source to the input terminals. Connect the output terminals to your load, ensuring correct polarity. Maintain adequate clearance around the unit to allow for proper air circulation, as the device relies on convection cooling to manage heat.

What to consider before purchase

• Verify that the 48 V DC output and 2 A current capacity meet the power requirements of your specific equipment.
• Ensure there is sufficient space on the DIN-rail for the unit dimensions.
• Confirm that the installation environment provides adequate ventilation for convection cooling.

For optimal performance and longevity, ensure the power supply is installed in a vertical orientation to maximize airflow and avoid placing heat-generating components directly beneath the unit.
