4. Setup and Installation
4.1 Mounting
Mount the power supply in a location that allows for proper airflow and heat dissipation. The unit utilizes forced air cooling via a built-in DC fan. Ensure the airflow direction (indicated in Figure 3.2) is not obstructed. The dimensions are 10.94 x 7 x 2.5 inches (L x W x H).
4.2 AC Input Connection
- Connect the AC Live (L) wire to Pin 1 (AC/L).
- Connect the AC Neutral (N) wire to Pin 2 (AC/N).
- Connect the Frame Ground (FG) wire to Pin 3 (FG).
Ensure all connections are secure and comply with local electrical codes. Use appropriate wire gauges for the expected current.
4.3 DC Output Connection
Connect your load to the DC output terminals. Observe correct polarity (+V and -V). For optimal performance and to minimize voltage drop, use thick, short cables for the DC output.
4.4 Grounding
Proper grounding is essential for safety and to minimize electromagnetic interference. Connect the FG terminal to a reliable earth ground.
5. Operating Instructions
5.1 Powering On/Off
Once all connections are made and verified, apply AC input power. The unit will power on. To power off, disconnect the AC input power or use the remote ON/OFF function.
5.2 Output Voltage Trimming
The output voltage (Vo) can be trimmed by an external control signal. Refer to the product datasheet for specific instructions on connecting the external control signal to the designated control pins (CN1/CN2/CN3) to adjust the output voltage within its specified range.
5.3 Remote ON/OFF Function
The RSP-2400-12 supports remote ON/OFF control. This function allows the power supply to be turned on or off remotely using an external signal. Refer to the diagram below for connection examples.
Figure 5.1: Graphs illustrating the power supply's derating curve based on ambient temperature and static characteristics based on input voltage. Also includes detailed diagrams and tables for implementing the remote ON/OFF function using external voltage sources or auxiliary outputs.
Remote ON/OFF Connection Methods:
The remote ON/OFF control is available via applying voltage in CN1 & CN2 & CN3. The table below summarizes the connection methods:
| Connection Method | SW Logic | Fig. 1.2(A) | Fig. 1.2(B) | Fig. 1.2(C) |
|---|---|---|---|---|
| Remote ON/OFF | Output on | SW Open | SW Close | SW Close |
| Output off | SW Close | SW Open | SW Open |
Figure 5.1 illustrates examples of connecting remote ON/OFF using an external voltage source (A) and using the internal 12V auxiliary output (B and C).
5.4 Load Considerations
The power supply's performance is affected by ambient temperature and input voltage. Refer to the Derating Curve and Static Characteristics graphs in Figure 5.1 to understand the maximum permissible load under different operating conditions. Ensure the load does not exceed the power supply's rated capacity, especially at higher ambient temperatures.
6. Maintenance
The RSP-2400-12 is designed for reliable operation with minimal maintenance. However, periodic checks can extend its lifespan and ensure optimal performance.
- Cleaning: Keep the power supply free from dust and debris. Use a soft, dry cloth or compressed air to clean the vents and casing. Ensure the unit is powered off and disconnected from AC input before cleaning.
- Fan Inspection: Periodically check the cooling fan for proper operation and ensure it is free from obstructions. A malfunctioning fan can lead to overheating and reduced lifespan.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent premature failure.
7. Troubleshooting
If you encounter issues with your RSP-2400-12 power supply, consider the following common troubleshooting steps:
- No Output Voltage:
- Check if the AC input power is connected and active.
- Verify that the remote ON/OFF function is not engaged (i.e., the unit is commanded to be ON).
- Inspect input and output wiring for loose connections or damage.
- Overload Protection:
- If the power supply shuts down or cycles, it may be due to an overload. Reduce the load connected to the output.
- Check for short circuits in the load.
- Over-Temperature Protection:
- If the unit is hot and shuts down, it may be due to over-temperature. Ensure adequate ventilation and that the fan is operating correctly.
- Reduce ambient temperature if possible.
If the problem persists after performing these checks, contact customer support.
