Low-Voltage Transformer for Pool and Garden Lighting

Waterproof Transformer Specifications

All specifications are finalized in the approved drawing. IP rating applies to the complete finished assembly under the agreed test and installation conditions.

Six Reasons Engineers Specify a Custom Waterproof Transformer

Where Waterproof Transformers Are Used?

Why OEM Buyers Choose ECKO for Waterproof Transformer Projects

Application-Based Engineering

We review the load type, duty cycle, cable distance, ambient temperature, installation zone and target safety requirements before finalizing the transformer. This helps avoid incorrect VA selection, excessive temperature rise and unstable output voltage.

Electrical and Mechanical Design in One Project

The transformer winding, magnetic core, enclosure, resin, cable gland and mounting structure are developed as one complete assembly. This is especially important when IP protection and thermal performance must be achieved at the same time.

Controlled Design Documentation

Input, output, wire size, protection components, dimensions, cable pinout and label information are recorded in the approved drawing. Engineering changes can therefore be reviewed and controlled before they enter production.

Waterproofing Beyond an Outer Coating

A reliable waterproof design depends on the resin, housing, cable jacket, cable entry, strain relief, curing process and installation method. ECKO evaluates these details instead of relying only on an external waterproof label.

Prototype and Production Capability

Established in 2000, ECKO operates three workshops covering approximately 5,000 square metres with 150 skilled workers and annual capacity of around one million wound-component products Prototype lead time can be as fast as 1–3 days when the required materials are available.

Technical Support from Sample to Mass Production

Customers can confirm electrical performance, dimensions, cable assembly, label and installation fit with a prototype before production. Inspection requirements and project-specific test reports can be agreed during sample approval.

Quality Testing

Waterproof Transformer Inspection and Validation

Routine electrical tests and design-validation tests serve different purposes. The final test limits and inspection frequency should be recorded in the approved specification or Control Plan.

Quality Statement:

Every shipment follows the approved product specification. Test records, inspection reports or project-specific validation data can be discussed during the quotation and sample-approval stage.

From Application Requirements to Production-Ready Waterproof Transformer

Step 1 — Application Review

Send the input voltage, output voltage, rated current, load type, cable distance, ambient temperature, IP requirement and installation information.

Step 2 — Engineering Evaluation

ECKO evaluates transformer capacity, winding design, voltage regulation, temperature rise, insulation, protection components, enclosure and cable assembly.

Step 3 — Quotation and Drawing

You receive a commercial quotation together with the proposed electrical and mechanical specification. Key parameters are confirmed before prototype production.

Step 4 — Prototype Manufacturing

A custom sample is manufactured using the agreed materials and construction. Sample lead time can be as fast as 1–3 days for suitable projects with available materials.

Step 5 — Sample Verification

The customer checks electrical performance, dimensions, mounting, cable connections and operation with the actual equipment. Any required changes are reviewed before approval.

Step 6 — Pilot Run and Mass Production

After sample approval, production follows the confirmed drawing, materials and inspection requirements. A pilot quantity can be arranged when additional validation is required.

Step 7 — Final Inspection and Delivery

Finished products are inspected and packed according to the agreed specification. Carton, pallet, private-label packaging and export documentation can be customized.

Waterproof Transformers FAQ

1. What is a low voltage outdoor lighting transformer?

A low voltage outdoor lighting transformer converts mains electricity, such as 110V, 120V, 220V, 230V or 240V AC, into a safer low voltage—typically 12V or 24V. It is commonly used to power landscape lights, garden lights, pathway lights, spotlights and other outdoor lighting fixtures.

2. Should I choose a 12V or 24V outdoor lighting transformer?

A 12V transformer is suitable for small residential landscape lighting systems and shorter cable runs. A 24V transformer is generally preferred for larger installations or longer cable distances because it reduces current and helps control voltage drop. The final choice should match the rated voltage of the lighting fixtures.

3. What is the difference between an AC and DC outdoor lighting transformer?

An AC transformer supplies alternating-current output, while a DC power supply provides direct-current output. Traditional landscape lights commonly use 12V AC or 24V AC, but some LED fixtures require DC input. Always confirm the voltage type marked on the light before selecting the transformer.

4. How do I calculate the required transformer wattage?

Add the rated wattage of all connected lighting fixtures and include a suitable safety margin. For example, a system with a total lighting load of 160W would normally require at least a 200W transformer. Continuous operation below approximately 80% of the transformer’s rated capacity is generally recommended.

5. Can I use a transformer with a higher wattage than my lighting load?

Yes. A transformer can have a higher rated power than the actual lighting load, provided its output voltage and frequency are compatible with the fixtures. Extra capacity can also allow additional lights to be installed later. However, extremely light loads should be checked if the transformer has a specified minimum load.

6. Can one transformer power multiple outdoor lights?

One transformer can supply multiple landscape lighting fixtures as long as their combined wattage does not exceed the recommended transformer load. The fixtures are normally connected in parallel so that each light receives the correct output voltage.

7. How far can outdoor lights be installed from the transformer?

There is no single maximum distance because it depends on the output voltage, total power, cable size and circuit layout. Long cable runs may produce excessive voltage drop. Using thicker cable, a 24V system, multiple cable runs or centrally positioning the transformer can help maintain stable voltage.

8. What causes voltage drop in a landscape lighting system?

Voltage drop is mainly caused by long cable runs, small conductor sizes and high current. It can make lights near the end of the circuit appear dimmer. The problem can be reduced by increasing the cable size, shortening the cable run, dividing the load into separate circuits or selecting a higher system voltage.

9. What cable size should be used for low voltage outdoor lighting?

Cable size should be selected according to the transformer output current, cable length, installation method and acceptable voltage drop. Larger loads and longer distances normally require thicker copper cable. The cable must also be suitable for outdoor, underground or wet-location installation as applicable.

10. Can a low voltage lighting transformer be installed outdoors?

Only transformers designed and rated for outdoor use should be installed outdoors. The enclosure, cable entries and connections must provide suitable protection against rain, moisture, dust and environmental exposure. Installation requirements should always follow the product instructions and local electrical regulations.
