FAQs
What is the maximum current output for this power supply?
The power supply has a rated output power of 120W. At 48V DC, this corresponds to a maximum rated output current of approximately 2.5A (120W / 48V = 2.5A).
Can this power supply be used in extremely cold environments?
Yes, it has a wide operating temperature range of -20°C to 60°C, making it suitable for use in cold environments within this range.
What type of DIN rail does this power supply mount on?
It is designed to be installed on standard TS-35/7.5 or TS-35/15 mounting rails.
Does the power supply come with pre-attached cables?
No, this power supply requires user wiring for both AC input and DC output connections to the appropriate terminals.
What are the built-in protection features?
It includes Overload protection, Short-Circuit protection, Over-Voltage protection, and Over-Temperature protection.
What is the efficiency rating of this power supply?
The Digitus DN-PWR12048 has a typical efficiency of 88%.
How should I handle potential heat generated by the metal housing?
Ensure adequate airflow around the power supply. Do not install it tightly packed with other heat-generating components without proper ventilation considerations.
Troubleshooting
No DC output voltage
Verify AC input voltage is within the 90-264V range. Check all wiring connections for security and correct polarity. Ensure the unit is not in an over-load or over-temperature protection state.
Output voltage is unstable or fluctuating
Confirm the load connected does not exceed the 120W (approx. 2.5A at 48V) capacity. Check for loose connections on the output side. Ensure input AC voltage is stable.
Device connected to power supply shuts down intermittently
This could indicate over-load or over-temperature protection is activating. Reduce the connected load or improve ventilation around the power supply. Check if the connected device is drawing excessive current.
Short circuit protection activated
Disconnect the load immediately. Inspect the connected devices and wiring for any short circuits. Address the short circuit issue before reconnecting power.
Pros and Cons

Setup, Compatibility & Care
Setup:
- Mounting: Securely attach the power supply to a TS-35/7.5 or TS-35/15 DIN rail using the integrated mounting clip.
- Wiring AC Input: Connect the appropriate AC input voltage (90-264V AC) to the designated input terminals. Ensure correct polarity and secure connections.
- Wiring DC Output: Connect your 48V DC devices to the output terminals. Observe correct polarity (+/-) to prevent damage.
- Grounding: Ensure the metal housing is properly grounded for safety.
Compatibility:
- Input Voltage: Compatible with standard AC mains voltage ranges worldwide (90-264V AC).
- Output Voltage: Primarily designed for devices requiring a stable 48V DC power source. Check your device specifications.
- Mounting: Fits standard TS-35 DIN rails.
Care:
- Ventilation: While the metal housing aids heat dissipation, ensure adequate airflow around the unit. Avoid installing in completely sealed, unventilated enclosures without considering heat buildup.
- Cleaning: Disconnect power before cleaning. Wipe the exterior with a dry or slightly damp cloth. Do not use abrasive cleaners or solvents.
- Inspection: Periodically inspect wiring and connections for signs of wear or damage.
