About this transformer

This HydroQuip 240V to 24VAC transformer (part #48-0099X-240) powers the control systems in spas equipped with HydroQuip control packs. Operating on 240V input voltage, this OEM transformer steps down power to 24VAC for safe operation of your spa's control circuits, display panels, and sensors. The unit includes three different plug types for versatile installation compatibility across various HydroQuip control pack configurations.

At Bubbles Supply, this genuine HydroQuip transformer comes with our exact fit guarantee, ensuring proper voltage conversion and reliable performance in your spa system. We ship same-day from our Canadian warehouse and back every transformer with a full 1-year warranty for complete peace of mind.

Before you buy — quick checklist

  • Confirm your existing transformer is rated 240V input — do not install this unit on a 120V system
  • Verify the output is 24VAC — some HydroQuip packs use a different secondary voltage
  • Check the plug configuration on your existing transformer against the three plug options included with this unit
  • Test the transformer output with a multimeter before condemning it — confirm input voltage is present at the primary
  • Inspect the control pack board for secondary damage that may have been caused by transformer failure

Reading the checklist now prevents 90% of returns. Worth the 60 seconds.
