United C5 Spa Packs

control-box-canada-united-c5C5 spa pack control boxes with the new B8 board now ship with new dual-voltage transformers. No more swapping out transformers to switch between 240V and 120V power hook-ups.

With these new transformers, and the addition of two additional 2-wire receptacles to the B8 board, incoming power voltage can be switch by moving the transformer’s 2-pin power selector plug between the B8’s 120V and 240V receptacles.

With the new dual-voltage transformers, the C5 control series are now the only controls on the market that come “out of the box” ready to operate at 120V or 240V (3-wire or 4-wire), at 50Hz or 60Hz, and configurable to 40 different hardware configurations.

That makes any C5 capable of operating almost any spa, anywhere in the world, right out of the box! If you need shipping to Europe or other international destination, please contact our support team for a freight quote.

In Canada, this spa pack ships free!
