Toroidal Transformer 230/12V for Pool Projector – CCEI (100 to 600VA)

230V/12V Toroidal Transformer for Pool Projectors — 100, 300 or 600 VA

The 230V/12V toroidal transformer is the central electrical component of any extra-low safety voltage power supply system for pool projectors. This transformer lowers the household electrical grid voltage (230V) to 12V AC, the regulatory voltage required by standard NF C 15-100 for all immersed lighting or lighting installed near a pool. It is available in three power ratings: 100 VA, 300 VA, and 600 VA, to adapt to all lighting configurations, from a single projector to multi-niche installations. Each transformer includes a neutral protection fuse, which secures the installation in case of overload or short circuit.

Why the toroidal transformer? Reliability, efficiency, and silence

The toroidal transformer stands out from classic EI core transformers due to its toroidal geometry—a closed ring wound with copper wire. This design offers several decisive advantages for a pool installation.

Energy efficiency is superior: a toroidal transformer converts energy with fewer thermal losses than a standard transformer, meaning it heats up less during operation. This is a significant asset when installed in a closed electrical box, where heat dissipation is limited. Operating noise is also reduced—unlike EI transformers which produce an audible hum at 50 Hz, the toroidal transformer operates almost silently. For a technical room located near a living area or terrace, this acoustic discretion makes all the difference.

Finally, the compact design of the toroidal transformer reduces bulk in the electrical box while maintaining the necessary nominal power. This is why manufacturers like CCEI equip their Piccolo PIMT and PIRF power supply boxes with this type of transformer as standard.

Three power ratings to cover all lighting configurations

The choice of power depends on the number and cumulative power of the connected projectors. You must add the consumption of each projector and select the version whose capacity is greater than or equal to this total.

The 100 VA transformer (dimensions Ø 12.5 cm × h. 6 cm) today covers a large majority of modern residential installations equipped with LED mini-projectors. A screw-on LED mini-projector usually consumes between 10 and 15W—a pool can therefore be equipped with five to eight LED mini-projectors with a 100 VA transformer. Even an installation with two 40W LED projectors remains within the limits of this power. The 100 VA is therefore the economical and sufficient solution for most small to medium-sized residential pools equipped with LED technology.

The 300 VA transformer (dimensions Ø 12.5 cm × h. 6 cm) is suitable for installations with several medium-power projectors, or with a LED/halogen mix. It can power up to 300 VA cumulatively—for example, two 150W halogen projectors, or about fifteen 20W LED mini-projectors, or four 70W LED projectors. This is the intermediate power for medium to large pools with several distributed light points.

The 600 VA transformer (dimensions Ø 14 cm × h. 5.5 cm) is the high-power version for large pools equipped with multiple PAR56 halogen niches. Its capacity allows it to support up to four 150W halogen projectors or the equivalent in high-power LEDs. This version has become less common with the generalization of LEDs, but remains essential for existing halogen installations or for collective pools with a large number of projectors.

Integrated neutral protection fuse: safety and easy diagnostics

Each transformer includes a neutral protection fuse, which secures the installation in case of overload or short circuit. In case of failure, the fuse cuts the power before the transformer is damaged or a fire risk develops.

This fuse is replaceable—if your pool lighting no longer works even though 230V power is present at the control box, a blown fuse is often the first cause to check before replacing the entire transformer. A fuse that blows repeatedly generally indicates an overload (total power of the projectors exceeding the transformer's capacity) or a short circuit on a projector or a damaged cable.

Replacement in a CCEI Piccolo enclosure or custom installation

This transformer is the intended replacement part for CCEI Piccolo PIMT and PIRF enclosures. If your enclosure no longer works and the fuse is intact, the transformer may be at fault—especially if it has been subjected to prolonged overload, mains overvoltage, or high temperature conditions. Replacing the transformer alone is often more economical than replacing the entire enclosure, provided that the rest of the installation (connectors, switch) is in good condition.

This transformer can also be used in custom installations, in a personalized electrical enclosure or to replace a faulty transformer of another brand, provided that the characteristics match: 230V AC input / 12V AC output, and power equal to or greater than the total power of the connected projectors.

Universal compatibility with all 12V AC projectors

This transformer is compatible with all 12V AC pool projectors, regardless of their brand or technology: PAR56 halogen projectors, screw-in LED projectors, niche LED projectors, 12V replacement bulbs. The projector simply needs to be designed to operate on 12V AC—not to be confused with 12V DC (direct current), which requires a different type of power supply.
