Intermatic PX100 Safety Transformer – 100W Pool & Spa Lighting Power Supply
Part # PX100 — a 100-watt low-voltage safety transformer designed to power 12-volt pool and spa lights. This transformer isolates line voltage from underwater fixtures, providing a safe and reliable power source for incandescent, LED and fiber-optic lighting.
Key Features
- 100-watt output rating suitable for most single 12-volt pool or spa light installations.
- Built-in resettable circuit breaker for overload and short-circuit protection.
- Fully enclosed, corrosion-resistant housing for long-term outdoor and equipment-pad use.
- Designed for low-voltage underwater lighting systems requiring NEC-compliant isolation.
- Compatible with many standard 12-volt pool and spa light models.
Typical Applications
Ideal for powering low-voltage pool lights, spa lights, water feature lights, and landscape fixtures installed near aquatic environments. Used when replacing failed transformers or converting lighting systems to safer low-voltage operation.
Installation & Compatibility Notes
Turn off power at the breaker before installation. Mount the PX100 in a dry, ventilated location near the equipment pad. Connect line voltage to the primary terminals and run 12-volt lighting circuits from the low-voltage secondary leads. Ensure all connections follow local codes and that lighting fixtures are rated for 12-volt operation.
Why Choose This Transformer?
The PX100 delivers safe isolation between high-voltage supply and underwater fixtures, helping prevent electrical hazards. Its durable construction and built-in protection devices ensure long-lasting and dependable lighting performance.
Maintenance Tips
- Inspect wiring annually for corrosion, loose connections or heat damage.
- Check the transformer housing for moisture intrusion and ensure ventilation remains unobstructed.
- If the resettable breaker trips frequently, inspect downstream wiring and fixtures before resetting.
- Keep the transformer mounted above ground level to prevent water exposure during heavy rain or flooding.
