Jewenwils Low Voltage Transformer
SKU: HOSL05E
[Instruction Manual]
Important Safety Information
[Warning] Please read the instructions with caution before operating and keep it properly.
Safety Instructions
- 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 the cord or plug.
- Do not submerge the 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 systems only.
- The maximum output of this transformer is 300 watts. Do not overload the transformer. Ensure that the total cumulative wattage of all 12-volt fixtures connected to the transformer is equal to or less than 300 watts.
CAUTION: This landscape light system must be installed in accordance with all local codes and ordinances. If you are experiencing problems, contact a qualified electrician.
Calculate Lighting Capacity
The 300 Watt transformer has circuits that will power up to 300 watts of light. To ensure the maximum number of fixtures can be safely connected, add up the individual wattages of all the fixtures. The total wattage of your fixtures must not exceed the output capacity of the 300 Watt transformer.
Installation
1. Preparing the Cable
Be careful when splitting the cable. Do NOT expose the copper cable. Remove the landscape cable insulation 1/2 inch (12.7mm) from both cables and twist ends.
Diagram: Shows a landscape cable being carefully split, and insulation removed from the ends to expose copper wire, marked with 1/2 inch (12.7mm).
2. Connecting the Cable to the Transformer
Lay the transformer on a flat, stable surface and use a screwdriver to connect the stripped ends of the cable under the terminal clamping plate.
Tips:
- Thread your cable through the white plastic loop to reduce its gravity.
- The terminal block has 3 groups of wiring ports (COM/12V/14V for each group). You can choose any group to connect your cable. For each group, there are 2 terminal output ends: 12V/14V. Select the appropriate terminal according to your lamp voltage.
Diagram: Illustrates the terminal block with three groups of COM, 12V, 14V connections. Includes a note: "Gently pull on the landscape cable to verify if the connection is strong."
3. Placing Your Fixtures and Routing the Cable
Lay your fixtures (not included) to your desired location. Ensure they do not exceed the 300-watt rating of the transformer. Coil the rest of the cable after the last fixture.

4. Attaching Your Fixtures
Use the cable connectors to attach your fixtures to the cable. Plug the transformer into the GFCI outlet and set it to the ON mode. The lamps will then light up.
5. Mounting the Transformer
Use a screw to mount the transformer directly on a wall. Mounting it 12 inches to 48 inches (0.3 m to 1.2 m) high from the ground is suggested.
Diagram: Shows the transformer mounted on a wall, approximately 12-48 inches (0.3-1.2m) from the ground, with its power cord plugged into a GFCI outlet, and landscape lighting cables running to outdoor lights.
Product Layout
Diagram: A detailed view of the transformer's front panel, labeling the "Zone Indicator" (light indicating selected output port), "Zone Selection Button" (to choose output port), "Digital Display" (showing status, e.g., "8.8."), "Auto Button" (for AUTO MODE), "Countdown Button" (for COUNTDOWN Mode and time setting), and "Manual ON/OFF Button" (for manual control).
Operating Instruction
The transformer offers several operating modes:
- Figure 1: OFF MODE
The selected output port has no voltage, and the load lamps are off. (Display shows "00") - Figure 2: ON MODE
The selected output port maintains output throughout the day, and the load lamps are always on. (Display shows "ON") - Figure 3: AUTO MODE
The transformer detects the environment for 0-30 seconds. If it's night, lamps turn on automatically and off at dawn. If it's daytime, lamps remain off. (Display shows "AU")
Note: If light from the load lamps shines on the sensor at night, it may cause continuous switching and flashing lamps. - Figure 4 & 5: COUNTDOWN MODE
The transformer detects the environment for 0-30 seconds. If it's night, lamps turn on and then turn off automatically after the set countdown duration. If it's daytime, lamps remain off. (Display shows "0" or "12" for countdown hours)
Note: If ambient light shines on the sensor for over 30 seconds during countdown, the countdown ends, output stops, and lamps turn off.
Important Tip: After installation, remove the protective cap from the photocell sensor to expose it to light.

Cable Selection Chart
This chart provides a guideline for selecting the appropriate cable gauge (AWG) based on total fixture wattage and cable length for both 12 Volt and 14 Volt taps.
12 VOLT TAP
| Total Fixture Wattage | Cable Length (0-50 feet) | Cable Length (51-100 feet) | Cable Length (100-150 feet) |
|---|---|---|---|
| 0-60 Watts | 16 AWG | 16 AWG | 14 AWG |
| 61-120 Watts | 16 AWG | 14 AWG | 12 AWG |
| 121-180 Watts | 14 AWG | 12 AWG | Not Recommended |
| 181-240 Watts | 14 AWG | 12 AWG | Not Recommended |
| 241-300 Watts | 12 AWG | Not Recommended | Not Recommended |
14 VOLT TAP
| Total Fixture Wattage | Cable Length (0-50 feet) | Cable Length (51-100 feet) | Cable Length (100-150 feet) |
|---|---|---|---|
| 0-60 Watts | 16 AWG¹ | 16 AWG | 16 AWG |
| 61-120 Watts | 16 AWG¹ | 16 AWG | 12 AWG |
| 121-180 Watts | 14 AWG¹ | 14 AWG | 12 AWG |
| 181-240 Watts | 14 AWG¹ | 14 AWG | 12 AWG |
