Waterproof Transformer for Pool and Landscape Lighting

Typical 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 does IP67 mean for a waterproof transformer?

IP67 generally indicates that the complete enclosure is protected against dust and temporary water immersion under defined test conditions. It does not automatically mean that the transformer is suitable for permanent underwater installation.

2. What is the difference between IP65, IP67 and IP68?

IP65 is commonly used for protection against dust and water jets. IP67 adds protection against temporary immersion under defined conditions. IP68 requirements depend on the agreed depth, duration and test conditions and must be specifically validated for the finished product.

3. Can an IP67 transformer be installed underwater permanently?

Normally, no. An IP67 transformer used for pool or fountain lighting is generally installed outside the water in a compliant electrical zone. Permanent underwater installation requires a specifically designed and validated solution, together with confirmation of local electrical regulations.

4. Does a waterproof transformer provide AC or DC output?

A conventional transformer provides AC output. If the equipment requires DC output, a rectifier, filter and possibly a voltage regulator must be added, creating a complete waterproof power supply rather than only a transformer.

5. How do I select the correct VA rating?

Add the power consumption of all connected loads and consider startup current, continuous operating time, ambient temperature and cable voltage drop. ECKO recommends selecting the transformer based on actual current and load characteristics rather than only the nominal wattage.

6. Can you customize 110V, 120V, 220V, 230V or 240V input?

Single-input, dual-input and multiple-tap primary windings can be designed. The input tolerance, frequency and target market should be provided when requesting a quotation.

7. Can you customize 12V or 24V output for pool and landscape lights?

Common outputs include 12V, 18V, 24V, 36V and 48V AC. The required output should be confirmed under load, especially when long cables may create a significant voltage drop.

8. Can one waterproof transformer have multiple outputs?

It can have multiple voltage outputs, a center-tapped output or separate isolated secondary windings. Please specify whether the loads operate simultaneously and whether the outputs must be electrically isolated from each other.

9. How does cable length affect the output voltage?

Long cables cause voltage drop, particularly with low-voltage, high-current loads. Provide the cable length, conductor size and operating current so the transformer output and cable specification can be evaluated together.

10. Can the transformer work at both 50Hz and 60Hz?

A transformer can be designed for 50/60Hz operation. A transformer designed only for 60Hz should not automatically be used at 50Hz because the lower frequency may increase magnetic flux, no-load current and temperature rise.
