- 두 개 이상의 변압기를 병렬로 연결하지 마십시오.
- 변압기 작동 중에는 어린이가 변압기에 가까이 가지 않도록 하십시오.
3. 설정 및 설치
Careful installation ensures optimal performance and safety.
3.1 변압기 장착
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)
- Ensure the main power supply is OFF at the circuit breaker before proceeding.
- Connect the 120V AC input power to the designated terminals inside the transformer. Follow local electrical codes for wiring connections.
- 모든 연결 부분이 안전하고 적절히 절연되어 있는지 확인하세요.
3.3 Connecting Low-Voltage Output (12V/13V/14V/15V AC)
- 저용량 연결tage 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.
- 모든 연결부가 단단히 고정되고 방수 처리되었는지 확인하십시오.

4. 사용 설명서
The LTR-300-BK transformer offers flexible control options for your landscape lighting.
4.1 출력 볼륨 설정tage
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 voltag전자 드롭.
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.
- 타이머 모드: 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.
- 수동 켜기/끄기: 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. 유지관리
정기적인 유지보수는 변압기의 수명 연장과 최적의 성능을 보장합니다.
- 청소: 변압기 외부를 주기적으로 부드러운 천으로 청소하십시오.amp cloth. Do not use abrasive cleaners or solvents. Ensure the photocell sensor lens is clean and free of obstructions.
- 사이: 매년 모든 배선 연결부의 조임 상태와 부식 여부를 점검하십시오. 연결부가 헐거워지면 성능 저하 또는 안전상의 위험이 발생할 수 있습니다.
- 통풍: Ensure that the transformer's ventilation openings are clear of debris to allow for proper air convection cooling.
- 환경 조건: 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. 문제 해결
변압기에 문제가 발생하면 다음의 일반적인 문제 및 해결 방법을 참조하십시오.
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| 표시등이 켜지지 않습니다. | 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. |
| 불빛이 깜빡이거나 어둡습니다. | 권tage 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.
