Intermatic Incorporated, a leader in energy management solutions, today announced the offering of the PX50 Safety Transformer for pool and spa use.

This latest addition to Intermatic’s PX Series of transformers is a code compliant, 50 watt safety transformer designed to supply underwater pool lights, submersible fixtures and outdoor garden lights with 12 to 14 volts. The PX50 has been specially designed to operate reliably in harsh environments, such as high heat and humidity, as well as the chemicals typically found around pools and spas.

Intermatic designed the PX50 with critical safeguards built-in such as circuit protection that disconnects power to the transformer in case of defect or overload. The PX50 also features a grounded shield between primary and secondary windings to ensure safe operation. Compliant with NEC Code 680.23 for underwater luminaries, the PX50 is also in compliance with UL-379 and CSA TILB44A standards.

“Contractors and end users can be confident that the PX50 provides code-compliant safety specifically for pool and spa use,” says Intermatic Product Manager Ed Lang.

The PX50 also features:

  • Removable cover for easy access to isolated high and low voltage compartments
  • Knock-outs for quick and convenient wiring
  • Selectable output voltage of the secondary, depending on input connections

In addition, the PX50 is universally compatible with LED lighting systems. “As more users turn to energy efficient lighting, such as LED, it’s critical that they have access to a transformer that has been specifically tested for compatibility with LED lighting,” Lang said.

Other new offerings include the PJB4175 and PJB2175, light junction boxes specially designed for pools, pool-spa combinations and landscape applications. These rugged, easy-to-install J-Boxes support up to four pool and spa lights and are rated for luminaries, ensuring safe operation.
