Zodiac – Power supply PCB Magna TNG – R0821800

The Zodiac R0821800 is an original replacement power supply printed circuit board (PCB) designed for the Zodiac Hydroxinator MagnaPool iQ salt water chlorination system. As a core electronic component of the control unit, this board is responsible for managing and distributing the electrical power supply that drives the chlorinator’s operation. When the original board becomes faulty, damaged, or unresponsive, replacing it with this genuine Zodiac part restores full system functionality without the need to replace the entire control unit.

This PCB is identified as component number 4 in the official Zodiac MagnaPool iQ spare parts diagram, confirming its precise position within the system’s internal architecture. As an OEM (original equipment manufacturer) part, it is engineered to the exact same specifications as the factory-installed component, ensuring correct voltage handling, signal compatibility, and reliable long-term performance within the Hydroxinator MagnaPool iQ platform.

Technical characteristics and compatibility

The R0821800 power supply PCB is specifically engineered for use within the Zodiac Hydroxinator MagnaPool iQ chlorination system — a premium salt chlorinator range designed for magnesium mineral pool environments as well as traditional salt pools. The board integrates directly into the control enclosure and works in conjunction with other electronic modules such as the HMI Wi-Fi control card and cell cable assembly to deliver a complete, connected pool water treatment solution.

Because this is a genuine Zodiac spare part manufactured to OEM tolerances, it ensures direct plug-and-play compatibility with the target system. Using non-genuine alternatives risks electrical incompatibility, voided warranties, and unpredictable behaviour of the chlorination system. Installation should be carried out by a qualified pool technician or electrician, as this component interfaces directly with mains-level and low-voltage electrical circuits within the control unit.

Suitability and application

This replacement PCB is intended for pool owners and installers who operate a Zodiac Hydroxinator MagnaPool iQ system and are experiencing issues attributable to a failed or damaged power supply board. It is suitable for both residential and commercial pool installations where this specific Zodiac chlorinator platform is in use. The MagnaPool iQ system is typically deployed in mid-to-large residential pools and wellness-focused aquatic environments where magnesium mineral water treatment is preferred. If your system is displaying power faults, failing to energise the cell, or showing no response from the control panel, this power supply PCB is a key diagnostic replacement component to consider.
