The diode rectifier, also called a Graetz bridge, is a basic electronic component of hot tub control systems and pool automation. It serves to convert alternating supply voltage to the direct voltage needed for the operation of the control electronics.
This spare part is intended for service replacement in the event of a failure of the electronics of control panels or hot tub control units. A correctly dimensioned rectifier is key to the stable and safe operation of the entire device.
Always disconnect the power supply before replacement and verify compatibility with the specific type of control system. We recommend entrusting the installation to a qualified electrician.
