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.
