1. Introduction
This manual provides essential instructions for the safe and efficient installation, operation, and maintenance of the MEAN WELL HDR-60-24 Ultra Slim Step Shape 3SU DIN Rail Power Supply. Please read this manual thoroughly before using the product and retain it for future reference.
The HDR-60-24 is a 24 Volt, 2.5 Amp, 60 Watt power supply designed for DIN rail mounting in industrial and control applications.
2. Safety Instructions
Observe the following safety precautions to prevent injury or damage to the device:
- Installation must be performed by qualified personnel only.
- Ensure the power supply is disconnected from the main power source before any installation, wiring, or maintenance procedures.
- Verify that the input voltage range of the power supply matches the local AC supply.
- Do not operate the unit in environments exceeding its specified temperature and humidity limits.
- Avoid blocking ventilation openings to ensure proper heat dissipation.
- Do not open the power supply casing; there are no user-serviceable parts inside.
- Protect the unit from moisture, dust, and corrosive substances.
3. Setup and Installation
The HDR-60-24 is designed for mounting on a standard 3SU DIN rail.
3.1. Mounting
- Ensure the DIN rail is securely installed in a well-ventilated enclosure.
- Align the power supply with the DIN rail and push it firmly until it clicks into place.
- Ensure adequate clearance around the unit for air circulation (minimum 10mm top/bottom, 5mm side).

3.2. Wiring Connections
Refer to the terminal block labels on the unit for correct wiring. Use appropriate wire gauges for the current ratings.
- Input (AC): Connect the AC input wires to the 'L' (Line) and 'N' (Neutral) terminals. Ensure proper grounding to the 'FG' (Frame Ground) terminal. Input voltage range is 85 to 264 VAC.
- Output (DC): Connect the DC load to the '+V' and '-V' terminals. Observe polarity. The output is 24 VDC.
- Tighten all terminal screws to the specified torque (e.g., 4.4 Lb-in for input, 3.0 Lb-in for output, as indicated on the unit label).
3.3. Output Voltage Adjustment
The output voltage can be finely adjusted using the 'Vo Adj.' potentiometer located on the front panel. Use a small screwdriver to turn the potentiometer clockwise to increase voltage or counter-clockwise to decrease voltage within the specified range (typically 21.6V to 29V for a 24V model).
4. Operating Instructions
Once properly installed and wired, the power supply is ready for operation.
- Apply AC power to the input terminals.
- The green LED indicator on the front panel will illuminate, indicating normal operation.
- The power supply will provide a stable 24V DC output to the connected load.
- Ensure the total load current does not exceed 2.5 Amps (60 Watts).
5. Maintenance
The HDR-60-24 power supply is designed for long-term, reliable operation with minimal maintenance.
- Cleaning: Periodically inspect the unit for dust accumulation. If necessary, disconnect power and gently clean the exterior with a soft, dry cloth. Do not use liquid cleaners.
- Inspection: Regularly check wiring connections for tightness and signs of damage. Ensure ventilation openings remain clear.
- Environmental Conditions: Maintain the operating environment within specified temperature and humidity ranges to ensure optimal performance and lifespan.
6. Troubleshooting
If the power supply is not functioning as expected, consider the following common issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| No output voltage / LED off | No AC input power; Incorrect wiring; Internal fault. | Check AC input connections and power source. Verify wiring. If problem persists, unit may be faulty. |
| Output voltage too high/low | Voltage adjustment potentiometer setting; Overload condition. | Adjust 'Vo Adj.' potentiometer. Check load for short circuits or excessive current draw. |
| Unit shuts down intermittently | Overload; Over-temperature; Short circuit. | Reduce load. Ensure adequate ventilation. Check for short circuits in the load. Allow unit to cool down. |
If troubleshooting steps do not resolve the issue, contact qualified service personnel.
