The C5 Series electronic controls now feature our fifth generation electronic power board, the B11 power board. The new B11 board features 'zero-crossing' technology. This means th at the relays are now only engaged at the optimal zero crossing of AC power, which is easier on the relays, and easier on the components in the spa. Every trace on these boards have been carefully engineered, with low voltage circuitry separated from high-voltage circuitry, and utilizing solid brass bars instead of printed copper traces for high voltage power. This unique design ensures the safety and longevity of our control systems. C5 control boxes with the new B11 board now ship with our new dual-voltage transformers. The days of swapping out transformers to switch between 230V and 115V power hook-up are over! With these new transformers, and the addition of two additional 2-wire receptacles to the B11 board, incoming power voltage can be switched by moving the transformer's 2-pin power selector plug between the B8's 115V and 230V receptacles. With the addition of 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 115V or 230V (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!Includes: Topside, Topside Cord, Light Cord and 2-Spd Pump Cord. Sensors are included and are already installed in the heater.
