4. Safety Information and Legal Disclaimer

WARNING: Risk of electric shock. All installation and servicing must be performed by qualified personnel. Ensure the power supply is disconnected from the main power source before any installation, wiring, or maintenance procedures.

This device is designed for professional use and should be installed in an enclosure that provides adequate protection against accidental contact with live parts. Ensure proper grounding and ventilation as per local electrical codes and standards.

Legal Disclaimer: Part Status: Active. Type: Enclosed. Input: 90 ~ 264 VAC, 127 ~ 370 VDC. Applications: Household Appliances, ITE (Commercial). Voltage - Isolation: 3.75kV. Efficiency: 89%. Operating Temperature: -30°C ~ 70°C (With Derating).

5. Setup and Installation

Follow these guidelines for proper setup and installation:

1. Mounting: Mount the power supply in a well-ventilated area, ensuring adequate clearance for heat dissipation. The fanless design relies on convection cooling.
2. Input Wiring: Connect the AC input (L, N, and FG) to the designated input terminals. Ensure the input voltage is within the specified range of 90-264VAC or 127-370VDC.
3. Output Wiring: Connect the DC output (+V and -V) to your load. Observe correct polarity. Refer to the specifications for the output voltage and current ratings.
4. Grounding: Ensure the Frame Ground (FG) terminal is properly connected to earth ground to prevent electrical shock and ensure stable operation.
5. Load Considerations: Do not exceed the rated output power. Consider the 150% peak load capability for short durations if your application requires it.

6. Operating Instructions

Once installed, the UHP-200-12 operates automatically. The power-on LED indicator will illuminate when the unit is receiving power and functioning correctly. Monitor the load to ensure it does not exceed the power supply's continuous rating. The unit is designed for convection cooling, so maintaining proper airflow around the unit is essential for optimal performance and longevity, especially in higher ambient temperatures.

7. Maintenance

The UHP-200-12 is designed for minimal maintenance. Periodically inspect the unit for:

• Accumulation of dust or debris on the casing, especially around ventilation areas. Clean with a soft, dry cloth or compressed air if necessary.
• Loose wiring connections. Ensure all input and output terminals are securely fastened.
• Signs of physical damage or overheating.

Always disconnect power before performing any maintenance.

8. Troubleshooting

If the power supply is not functioning as expected, perform the following basic checks:

• No Output Voltage / Power LED Off:
  • Check the AC input power connection.
  • Verify the input voltage is within the specified range.
  • Ensure no short circuit exists at the output terminals.
• Output Voltage Fluctuating / Unstable:
  • Check if the load exceeds the rated power.
  • Ensure proper ventilation and operating temperature.
  • Verify all connections are secure.
• Over-temperature Protection Activated:
  • Reduce the ambient temperature.
  • Improve ventilation around the unit.
  • Reduce the load if it is consistently high.

If issues persist after these checks, contact technical support.
