The Jewenwils Low Voltage Transformer (SKU: HOSL08A) is a device designed to provide low-voltage power for outdoor landscape lighting systems. It is available in models such as DA-600-12W4-1.
Function Description
The primary function of this transformer is to convert standard household voltage (120VAC, 60Hz) to a lower, safer voltage (12VAC/14VAC) suitable for outdoor lighting fixtures. It features multiple zones, allowing for flexible power distribution to various lighting setups. The transformer can operate in different modes, including OFF, ON, AUTO, and COUNTDOWN, providing versatility in controlling the lighting system. It also incorporates safety features such as overload protection and short circuit detection to ensure reliable operation.
Important Technical Specifications
- Input Voltage: 120VAC, 60Hz
- Output Voltage: 12VAC/14VAC
- Max Power Rating: 600W (total), with each zone having a maximum output power of 300W.
- Transformer Wattage: The transformer itself can handle a maximum of 600W. Each zone can handle a maximum of 300W.
- Photo Sensor Cable Length: 6 ft
- Installation Distance: Do not install within 10 feet (3 m) of a pool, spa, or fountain.
- Mounting: Can be mounted directly on a wall (12 to 48 inches / 0.3 to 1.2 m high) or on the ground (12 to 48 inches / 0.3 to 1.2 m high).
- Cable Compatibility: The manual provides a cable selection chart based on total fixture wattage and cable length for both 12 Volt and 14 Volt taps. It specifies recommended AWG (American Wire Gauge) for different power and distance combinations. For instance, for 0-60 Watts and 0-50 feet, 16 AWG is recommended. For higher wattages and longer distances, thicker gauges like 14 AWG or 12 AWG are suggested. AWG¹ is not recommended for Halogen Landscape.
Usage Features
Safety Instructions:
- Important safety information to reduce risk of fire injury.
- Do not install within 10 feet (3 m) of a pool, spa or fountain.
- There are no serviceable parts inside the power supply unit. DO NOT DISASSEMBLE.
- Do not repair or tamper with cord or plug.
- Do not submerge transformer in water.
- Do not mount the transformer onto combustible material.
- Do not connect two or more transformers in parallel.
- Do not use the transformer with a dimmer switch.
- Plug the power supply unit directly into a GFCI wet location outlet.
- For use with low voltage outdoor landscape lighting system only.
- The maximum output of this transformer is 600 watts. The two zone of this transformer have total of 600w, 300w per zone. Do not overload the transformer. Be sure that the total cumulative wattage of all 12 volt fixtures connected to the transformer is equal to or less than 600 watts. Each Zone does not exceed 300w.
Installation:
- Preparing the Cable: Carefully strip the cable, exposing 1/2 inch from both cables and twist ends.
- Connecting the cable to the Transformer: Lay the transformer on a flat, stable surface. Use a screwdriver to connect the stripped ends of the cable under the terminal clamping plate.
- Tips:
- Wire under each terminal pressure plate and tighten screw securely. Make sure wire insulation clears pressure plate.
- For the following image shows, there are 3 group wiring ports (COM/12V/14V for each group), you can choose any group of them to connect your cable. For each group, there are 2 terminal output ends- 12V/14V, select the appropriate terminal according to your lamp voltage.
- Note: Gently pull on the landscape cable to verify if the connection is strong.
- Placing Your Fixtures and Routing the cable: Lay your fixtures (not included) to your desired location. Ensure they do not exceed the 600-watt rating of the transformer. Each Zone does not exceed 300w. Coil the rest of the cable after the last fixture.
- Attaching Your Fixtures: Use the cable connectors to attach your fixtures with the cable. Plug the transformer into the GFCI outlet and enter the ON mode. Then the lamps will light up.
- Mounting the Transformer: Use the screw to mount the transformer directly on a wall. 12 inch to 48 inch (0.3 m to 1.2 m) high from the ground would be suggested. 12in. to 48in. (0.3m to 1.2m).
Operating Instruction:
The transformer features a digital display and control buttons (up/down arrows and a mode/set button) for setting different operating modes.
- Figure 1: OFF MODE: The transformer does not work, there is no output voltage, and the load lamps will not light.
- Figure 2: ON MODE: The transformer will maintain the output throughout the day, and the load lamps will always be on.
- Note: If the "." on the display goes off after a few seconds, it means that the wiring of the lamp is abnormal or the wire is broken. You need to cut off the power supply of the transformer to eliminate the abnormal situation, then restart the power supply.
- Figure 3: AUTO MODE: In this mode, it will take 0 ~30s for the transformer to detect the external environment firstly. If it is night, the currently selected output port of the transformer will start output later, then the load lamps will light on automatically and off at dawn. If it is during the day, the currently selected output port of thetransformer will have no output and the load lamps will not light.
- Note: If the light emitted by the load lamps shines on the sensor at night, it may cause the transformer to continuously switch on/off, and the load lamps flash continuously, with a flash interval of 30s.
- Figure 4 & Figure 5: COUNTDOWN MODE: In this mode, it will also take 30s for the transformer to detect the external environment firstly. If it is night, the transformer will start output 30s later and the load lamps will light. Then they will turn off automatically when the countdown is over. If it is during the day, the transformer will have no output and the load lamps will not light.
- Note: When the system starts to count down, if the surrounding light shines on the sensor for more than 30s, the countdown will end, the transformer will stop output, and the load lamps will go out.
- Figure 6: FAILURE MODE: When the "F" lights, the outlet is overloaded or short circuit. To solve it, pull out the plug and check the circuit. Connect the power again after troubleshooting, the transformer will reset automatically.
- Selecting the function On-Auto-Countdown-Off: Use the up/down buttons to cycle through the modes.
Tips:
- When the transformer is working, the dot in the lower right corner of the display lights up. If the dot is not light up, it means that the transformer has no output voltage.
- The transformer has a power-off memory function. After the transformer has been working in the current mode for 24 hours, the transformer will remember the current working mode. When the transformer powers on again, the transformer will enter the working mode before the power failure.
- The transformer has two outputs with a total output power of 600VA. Each zone has a maximum output power of 300W.
