This unit features a built-in timer and photocell sensor for automated operation, converting 120V AC input to selectable 12V, 13V, 14V, or 15V AC output. It is weatherproof and UL certified, ensuring safety and reliability for your outdoor lighting system.
2. Sikkerhedsoplysninger
Read all instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or other hazards.
- Always disconnect power at the circuit breaker before installing, servicing, or performing any maintenance on the transformer or connected lighting fixtures.
- Installationen skal udføres af en kvalificeret elektriker i overensstemmelse med alle lokale og nationale el-forskrifter.
- This transformer is designed for outdoor use. Do not immerse the transformer in water.
- Sørg for korrekt jordforbindelse af transformeren.
- Do not overload the transformer. The maximum recommended load is 80% of the 300W capacity (240W).
- Forbind ikke to eller flere transformere parallelt.
- Keep children away from the transformer during operation.
3. Opsætning og installation
Careful installation ensures optimal performance and safety.
3.1 Montering af transformatoren
Mount the transformer vertically on a sturdy surface, such as a wall or post, using appropriate mounting hardware (not included). Ensure the transformer is mounted at least 1 foot (30 cm) above ground level to prevent water damage and allow for proper ventilation. The unit should be installed in a location that allows the photocell sensor to receive adequate ambient light for proper operation.

3.2 Wiring the Input Power (120V AC)
- Sørg for, at hovedstrømforsyningen er FRA ved afbryderen, før du fortsætter.
- Connect the 120V AC input power to the designated terminals inside the transformer. Follow local electrical codes for wiring connections.
- Sørg for, at alle forbindelser er sikre og korrekt isolerede.
3.3 Connecting Low-Voltage Output (12V/13V/14V/15V AC)
- Tilslut din lav-voltage landscape lighting cables to the output terminals of the transformer.
- The transformer offers multiple output voltage taps (12V, 13V, 14V, 15V AC) to compensate for voltage drop over long cable runs. Select the appropriate tap based on your lighting system's requirements and cable length. Higher voltage taps are typically used for longer cable runs to ensure consistent brightness.
- Ensure all connections are tight and weatherproof.

4. Betjeningsvejledning
The LTR-300-BK transformer offers flexible control options for your landscape lighting.
4.1 Indstilling af udgangsvolumentage
The transformer allows you to select an output voltage of 12V, 13V, 14V, or 15V AC. This selection is typically made via internal wiring terminals or a selector switch. Refer to the internal wiring diagram for specific instructions on how to adjust the output voltage to match your lighting system's needs and compensate for voltage drop.
4.2 Timer and Photocell Sensor Operation
The integrated timer and photocell sensor provide automatic control of your lighting system.
- Photocell Mode: The photocell sensor detects ambient light levels. In this mode, the lights will automatically turn on at dusk and turn off at dawn. Ensure the photocell is not obstructed and is exposed to natural light.
- Timertilstand: You can set the transformer to turn on at dusk and remain on for a specific duration (e.g., 4, 6, 8 hours). After the set duration, the lights will automatically turn off.
- Manuel ON/OFF: A manual override option allows you to turn the lights on or off independently of the timer or photocell settings.
Consult the control panel and user interface on the transformer for specific button functions and programming steps for the timer and photocell settings.
5. Vedligeholdelse
Regular maintenance ensures the longevity and optimal performance of your transformer.
- Rensning: Periodically clean the exterior of the transformer with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the photocell sensor lens is clean and free of obstructions.
- Forbindelser: Kontrollér årligt alle ledningsforbindelser for tæthed og korrosion. Løse forbindelser kan føre til dårlig ydeevne eller sikkerhedsrisici.
- Ventilation: Ensure that the transformer's ventilation openings are clear of debris to allow for proper air convection cooling.
- Miljøforhold: The transformer is designed to operate within a temperature range of -30°C to 45°C. Avoid exposing it to extreme conditions outside this range.
6. Fejlfinding
If you encounter issues with your transformer, refer to the following common problems and solutions:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Lysene tænder ikke. | No power to transformer, tripped circuit breaker, loose connections, faulty photocell/timer setting, overloaded circuit. | Check circuit breaker. Verify 120V AC input. Inspect all low-voltage connections. Adjust photocell/timer settings. Reduce load if overloaded. |
| Lysene flimrer eller er svage. | Voltage drop due to long cable runs, loose connections, insufficient wattage from transformer, faulty bulbs. | Select a higher output voltage tap (13V, 14V, or 15V). Tighten connections. Ensure total wattage of lights does not exceed 80% of transformer capacity. Replace faulty bulbs. |
| Photocell/Timer not working correctly. | Photocell obstructed, incorrect settings, internal fault. | Ensure photocell is clean and unobstructed. Verify timer and photocell settings. If issues persist, contact support. |
| Transformer makes unusual noise or smells. | Internal fault, overheating, short circuit. | Immediately disconnect power. Do not attempt to repair. Contact a qualified electrician or DALS Lighting support. |
The transformer includes protection features for short circuit and over voltage conditions. If a fault occurs, the unit may shut down. Disconnect power, identify and rectify the fault, then restore power.
