A custom 12V or 24V AC isolation transformer can supply low-voltage swimming pool lights from a 110V, 120V, 220V, 230V or 240V mains input. The transformer should be installed in a code-compliant location outside the pool according to local electrical regulations.
Waterproof transformer provide low-voltage power for garden lights, path lights, spotlights and other landscape lighting systems exposed to rain and humidity. Output voltage can be adjusted for cable length and expected voltage drop.
Fountain lights, misting systems and decorative water features often require isolated low-voltage power close to a humid operating area. Enclosure, potting resin, cable exit and mounting method are selected around the installation conditions.
The transformer can be customized for façade lighting, signage, courtyard lighting and commercial outdoor illumination. Multiple output windings or several lighting circuits can be considered during the design stage.
Waterproof transformer can supply low-voltage lighting, control circuits and auxiliary electrical equipment in spa and bathroom systems. The installation zone, insulation requirements and applicable safety standards must be confirmed before production.
Special waterproof transformer designs can be evaluated for marine auxiliary equipment, irrigation controls and wastewater systems. Salt, chlorine, chemicals, UV exposure and corrosion requirements should be specified during the engineering review.
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.
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.
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.
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.
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.
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.
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.
Send the input voltage, output voltage, rated current, load type, cable distance, ambient temperature, IP requirement and installation information.
ECKO evaluates transformer capacity, winding design, voltage regulation, temperature rise, insulation, protection components, enclosure and cable assembly.
You receive a commercial quotation together with the proposed electrical and mechanical specification. Key parameters are confirmed before prototype production.
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.
The customer checks electrical performance, dimensions, mounting, cable connections and operation with the actual equipment. Any required changes are reviewed before approval.
After sample approval, production follows the confirmed drawing, materials and inspection requirements. A pilot quantity can be arranged when additional validation is required.
Finished products are inspected and packed according to the agreed specification. Carton, pallet, private-label packaging and export documentation can be customized.
They can be used with LED pool lights that accept the transformer’s AC output voltage. If the LED light contains an electronic driver, dimming circuit or color-control system, its input requirements and startup current should be reviewed before the transformer is selected.
Common input options include 110V, 120V, 220V, 230V and 240V AC. Common output options include 12V, 18V, 24V, 36V and 48V AC.
Single-input, dual-input, multiple-tap and multiple-output configurations can be developed according to the project.
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.
Available options include:
The selected protection system should coordinate with the connected load, wiring and upstream circuit breaker.
Cable length, wire gauge, jacket material, color, cable gland, strain relief, terminals, plugs and waterproof connectors can be customized.
For outdoor and pool-light projects, please specify UV exposure, ambient temperature, chemical exposure and required connector type.
Depending on the approved specification, inspections may include:
The test limits and inspection frequency are recorded in the approved specification or Control Plan.
