2. Safety Information and Important Notes
Please read all safety instructions carefully before installation and operation to prevent injury or damage to the unit. Keep this manual for future reference.
- General Safety: This power supply is considered a component and must be installed into a final equipment. The final equipment must be re-confirmed to meet all relevant EMC directives.
- Input Voltage Selection: The unit supports both 88-132VAC and 176-264VAC input ranges, selectable via a switch. Ensure the correct voltage is selected before connecting to the AC mains.
- Environmental Conditions: Operate the power supply within the specified working temperature (-25°C to +70°C) and humidity (20% to 95% RH non-condensing) ranges. Avoid exposure to excessive moisture or extreme temperatures.
- Cooling: The unit is cooled by free air convection. Ensure adequate airflow around the power supply to prevent overheating.
- Protection Features: The power supply includes built-in protections against short circuit, overload, and over voltage. In case of a fault, the unit will enter hiccup mode and automatically recover once the fault condition is removed.
- Wiring: All parameters are measured at 230VAC input, rated load, and 25°C ambient temperature unless otherwise specified. Ripple and noise are measured with a 12" twisted pair-wire terminated with 0.1uF & 47uF parallel capacitors.
- Installation: Ensure proper grounding (FG) connection for safety.
- Power-On Sequence: Turning the power supply ON/OFF very quickly may increase the setup time.

4. Setup and Installation
Proper installation is crucial for the safe and reliable operation of the power supply. Refer to the mechanical specifications and terminal assignments for correct wiring.
4.1 Mechanical Dimensions and Mounting
The power supply features a compact design for easy integration. Ensure sufficient space for air circulation around the unit for optimal cooling.
Figure 1: Mechanical dimensions and mounting points of the RS-150-15 power supply. Dimensions are in millimeters. The unit measures 197mm (L) x 98mm (W) x 38mm (H).
Mount the power supply securely using the designated mounting holes as shown in Figure 1. Ensure the mounting surface is stable and can support the weight of the unit (approximately 0.7 kg).
4.2 Terminal Assignment
Connect the input and output wires according to the terminal assignments below. Use appropriate wire gauges for the current ratings to prevent overheating.
| Pin No. | Assignment | Pin No. | Assignment |
|---|---|---|---|
| 1 | AC/N | 4, 5 | DC OUTPUT -V |
| 2 | AC/L | 6, 7 | DC OUTPUT +V |
| 3 | FG (Frame Ground) |
Important: Ensure the Frame Ground (FG) terminal is properly connected to earth ground for safety.
4.3 Input Voltage Selection
The RS-150-15 has a switch to select between 88-132VAC and 176-264VAC input voltage ranges. Before connecting the power supply to the AC mains, verify that the switch is set to match your local AC supply voltage. Incorrect voltage selection can damage the unit.
5. Operating Instructions
Once properly installed and wired, the power supply is ready for operation.
- Power On: Connect the AC input to the power supply. The LED indicator on the unit will illuminate, indicating that the power supply is active.
- Output Voltage Adjustment: The output voltage can be adjusted within the range of 13.5V to 16.5V using the internal potentiometer. Use a voltmeter to accurately set the desired output voltage.
- Load Connection: Connect your DC load to the +V and -V output terminals. Ensure the load does not exceed the rated current of 10A or the rated power of 150W.
- Derating Curve: For operation at higher ambient temperatures or lower input voltages, refer to the derating curves in the specifications section to ensure the power supply operates within its safe limits.
Figure 2: Specification sheet for the RS-150-15, including derating curves and static characteristics. The derating curve illustrates the maximum permissible load at various ambient temperatures, while static characteristics show performance across input voltage ranges.
6. Maintenance
The MEAN WELL RS-150-15 power supply is designed for long-term, reliable operation with minimal maintenance. However, adhering to the following guidelines will help ensure its longevity:
- Keep Clean: Periodically inspect the unit for dust accumulation, especially around ventilation openings. Clean with a soft, dry cloth or compressed air. Do not use liquid cleaners.
- Ensure Airflow: Verify that the free air convection cooling is not obstructed. Maintain adequate clearance around the power supply.
- Environmental Control: Operate the unit within the specified temperature and humidity ranges. Avoid environments with high levels of corrosive gases or excessive vibration.
- Connection Integrity: Periodically check all input and output connections to ensure they are secure and free from corrosion.
7. Troubleshooting
If the power supply is not functioning as expected, consider the following common issues and their solutions:
- No Output / LED Off:
- Check the AC input connection and ensure power is supplied to the unit.
- Verify the input voltage selection switch is set correctly for your AC mains.
- Inspect the input fuse (if accessible and replaceable) for continuity.
- Intermittent Output / Hiccup Mode:
- This indicates that one of the protection features (short circuit, overload, or over voltage) has been activated.
- Disconnect the load and check for short circuits in your external circuit.
- Ensure the load current does not exceed 10A and the power does not exceed 150W.
- Check if the output voltage is set too high (above 16.5V).
- Allow the unit to cool down if it has been operating in a high-temperature environment, as over-temperature protection may be active.
- Output Voltage Incorrect:
- Use a voltmeter to measure the output voltage.
- Adjust the internal potentiometer to set the desired output voltage within the 13.5V to 16.5V range.
- Ensure the load is not drawing excessive current, which could cause voltage drop.
If the problem persists after performing these checks, contact qualified service personnel.
