NSI TORK TPX100 100W Low-Voltage Safety Transformer — Beige, 12V LED-Compatible, UL/CSA Rated

The NSi TORK TPX100 is a 100-watt, low-voltage safety transformer engineered to power 12V underwater pool and spa lights, landscape fixtures, fountains and LED-compatible decorative lighting safely indoors or outdoors.

The TPX100 combines heavy-duty steel construction, built-in overload protection and multiple wiring options to provide a reliable step-down transformer for residential and light commercial low-voltage lighting systems. It meets UL and CSA safety standards and is designed to comply with NEC requirements for underwater luminaires, making it suitable where code-compliant, dependable power is required for 12-volt lighting loads.

How does the TPX100 keep pool and landscape lighting safe?

The unit includes auto-reset overload protection and a grounded shield to reduce electrical risk in wet-location installations. If an overload occurs, the protective circuit disconnects and then automatically resets, helping prevent sustained faults while minimizing manual intervention.

• Built-in auto-reset overload protector for transient faults
• Grounded shield to help isolate the low-voltage compartment
• UL Listed and CSA Approved for safety assurance
• Meets NEC article 680.23 for underwater luminaires where applicable

Will this transformer work with LED and other bulb types?

The TPX100 is compatible with incandescent, compact fluorescent and LED light sources, so it works across common lamp technologies used in pools, spas, gardens and decorative features. Its stable 12V output supports modern low-voltage LED fixtures while remaining backward-compatible with older halogen or incandescent designs.

• 12-volt output suitable for LED retrofit and native LED fixtures
• Supports incandescent and compact fluorescent lamps
• 100-watt capacity for multi-fixture runs or higher-wattage single fixtures
• LED-compliant design to avoid compatibility issues

How easy is installation and maintenance?

The enclosure is built for straightforward installation with multiple knockout sizes, separate high- and low-voltage compartments, and built-in mounting brackets for secure placement. Heavy-duty steel construction simplifies long-term service and helps protect internal components from environmental exposure in covered outdoor or indoor locations.

• Multiple 1/2-inch and 3/4-inch knockouts for conduit flexibility
• Distinct high- and low-voltage wiring compartments to streamline hookups
• Included mounting brackets for secure, code-friendly installation
• Durable steel enclosure for long-lasting field use

What codes and ratings does the TPX100 meet?

The transformer is UL Listed, CSA Approved as a Class II device and designed to meet National Electrical Code requirements for underwater luminaires where applicable. These ratings make it appropriate for both residential pool and landscape applications when installed per local codes and manufacturer instructions.

• UL Listed for recognized safety standards
• CSA Approved Class II for electrical compliance
• Designed to meet NEC article 680.23 for underwater luminaires
• LED compliant for modern lighting installations

Who is this for? The NSi TORK TPX100 is aimed at homeowners, landscape contractors and pool/spa professionals who need a reliable, code-conscious low-voltage transformer capable of powering underwater and outdoor accent lighting. It suits projects requiring a 100-watt capacity with easy wiring options and built-in safety features — especially installations that demand compatibility with LED fixtures and adherence to UL/CSA/NEC standards.
