The ABBA Lighting USA STS150 is a 12V landscape light specialist transformer designed for both indoor and outdoor applications, offering a secure and dependable solution for electrical needs in various environments. This high-quality product is engineered to provide efficient power transmission for landscape lighting systems, with a maximum output capacity of 300 Watts.
Function Description:
The STS150 transformer serves as a central power unit for low-voltage landscape lighting. It converts standard household voltage to a safe 12V output, suitable for outdoor lighting fixtures. The device offers versatile operational modes, including continuous "On," "Off," "Auto (Photo Sensor)" for dusk-to-dawn operation, and "Countdown Timer" options (2, 4, 6, or 8 hours after dusk). Additionally, it features an "Astronomic Timer Mode" that automatically adjusts on/off times based on local sunset and sunrise, provided the user's city/location is correctly set in the accompanying smartphone app. The transformer can be controlled manually via its integrated interface or remotely through a smartphone app, offering convenience and flexibility in managing lighting schedules.
Important Technical Specifications:
- Rated Voltage: 12V
- Maximum Output Capacity: 300 Watts
- Wi-Fi Connectivity: Supports 2.4 GHz Wi-Fi networks for app control.
- Safety Features: Designed for direct plug-in to a Ground Fault Circuit Interrupter (GFCI) outlet to enhance protection against electrical shocks. It is recommended not to use an extension cord and to avoid connecting two or more transformers in parallel. The device should not be installed within 10 feet of a pool, spa, or fountain.
- Weatherproof: Engineered to be weatherproof, offering enhanced protection against the elements for outdoor use.
- Wire Gauge Recommendations: The manual provides a detailed chart for wire gauge selection based on combined wattage of fixtures and distance from the transformer (e.g., for 0-60 Watts, 16 gauge for 0-75' and 75-150', and 14 gauge for 150-250'; for 240-300 Watts, 12 gauge for 0-75', with "Not recommended" for longer distances).
Usage Features:
- Installation: The transformer should be mounted on a wall near an electrical outlet, between 12" and 48" (30 to 121 cm) from the ground, ensuring the controls are readily visible and accessible. It is crucial to avoid obstructing the dusk-to-dawn sensor.
- Wiring: Landscape wires (sold separately) should be prepared by stripping 1/2 inch of insulation and twisting the exposed ends tightly. Connections are made to "COM" and "15V" block terminals using levers to secure the wires. The manual emphasizes ensuring wires are fully inserted and securely positioned, with no loose or exposed wires.
- Power-Up and Testing: After installation, the transformer should be plugged into a GFCI outlet. Users can test the fixtures by setting the mode switch to "ON" and observing for proper illumination.
- Manual Settings: The transformer's interface allows for manual selection of "On," "Off," "Auto (Photo Sensor)," and "Countdown Timer" modes.
- Smartphone App Control (Smart Life - Smart Living):
- Wi-Fi Connection: The transformer connects to a 2.4 GHz Wi-Fi network. During setup, the LED indicator blinks to show it's connecting.
- Device Pairing: Users download the "Smart Life - Smart Living" app (available on App Store and Google Play Store), open it, and follow in-app instructions to add the transformer as a device. This involves selecting the Wi-Fi network, entering the password, and waiting for the connection to establish.
- ON/OFF Countdown Timer: Within the app, users can toggle the transformer on/off and enable a countdown timer when in "on" mode.
- Photo Sensor/Auto Mode: The app allows customization of the photo sensor mode, enabling users to set specific "off" times during the first period (Auto1) and "on" times in the early morning during the second period (Auto2), overriding the default dusk-to-dawn operation if desired.
- Timer Mode: Users can set specific on/off times and configure multiple on/off cycles throughout the day for greater flexibility.
- Astronomic Timer Mode: This mode automatically turns lights on and off based on local sunset and sunrise times. Users can also set specific "off" times during the first astronomic period (Astro1) and "on" times during the second astronomic period (Astro2).
- Wire Selection: When selecting cable gauge, it's important to consider the distance between the transformer and lighting fixtures to ensure efficient power transmission and minimize voltage drop. The manual provides a chart with recommendations.
Maintenance Features:
- Warranty: The product comes with a 2-year warranty from the date of purchase. The warranty is void if there is any damage due to improper usage or modification, or failure to comply with manual instructions.
- Troubleshooting: The manual provides tips for Wi-Fi connection issues, including ensuring the network is 2.4GHz, testing the Wi-Fi with other devices, moving the transformer closer to the router for better signal, and double-checking the Wi-Fi password for case sensitivity. It also refers users to the app user guide for more information.
- Safety Guidelines: Emphasizes the importance of professional installation, turning off power before installation, adherence to local codes, and avoiding disassembly of the unit. Regular inspection of terminal blocks for secure connections is recommended.
