5. Setup and Installation
Refer to the product label for detailed wiring instructions. Ensure all connections are secure and comply with local electrical codes.
Figure 1: Osram OT100W/347-480V/1250C/2DIM/P6 LED Power Supply. The label on the device details its model number, input voltage (347-480VAC), output current range (600-1250mA), dimming capabilities, and wiring connections for line, neutral, LED output, and dimming control.
Wiring Connections:
- Input (AC):
- Black wire: LINE
- White wire: NEUTRAL
- Output (DC to LED):
- Red wire: LED+
- Blue wire: LED-
- Dimming Control (0-10V):
- Purple wire: DIM+
- Pink wire: DIM-
- Grounding: Connect the power supply case to earth ground.
The dimming input is isolated. Ensure proper polarity for LED and dimming connections.
6. Operating Instructions
This LED power supply is a constant current, programmable driver. The output current can be programmed within the 600-1250mA range to match the requirements of the connected LED load.
Dimming Functionality:
The unit supports 0-10V dimming, allowing for light output adjustment from 100% down to 10%. Connect a compatible 0-10V dimmer to the purple (DIM+) and pink (DIM-) wires. A higher voltage on the dimming input corresponds to a higher light output.
7. Maintenance
The OSRAM LED Power Supply is designed for reliable operation with minimal maintenance. However, periodic inspection is recommended.
- Cleaning: Ensure the unit is free from excessive dust or debris, especially in outdoor environments. Use a dry, soft cloth for cleaning.
- Inspection: Periodically check wiring connections for tightness and signs of wear or damage.
- Servicing: Always disconnect power to the unit before performing any maintenance or inspection to prevent electrical shock.
8. Troubleshooting
If the LED power supply is not functioning as expected, consider the following:
- No Light Output:
- Verify input power is present and correctly wired (LINE, NEUTRAL).
- Check LED output connections (LED+, LED-) for correct polarity and secure contact.
- Ensure the LED load is compatible with the power supply's output voltage and current range.
- Dimming Issues:
- Confirm the 0-10V dimmer is compatible and correctly wired (DIM+, DIM-).
- Check dimming control voltage levels.
- Overheating:
- Ensure adequate ventilation around the power supply.
- Verify the ambient temperature is within the operating limits.
