This is the genuine Davey replacement power supply unit for the ProMatic MPS40 and MPS50 salt water chlorinator systems. It is the core electrical component that converts mains power and delivers the correct output to drive electrolysis in the chlorinator cell, keeping your pool sanitised automatically. This part is available while stocks last and is not expected to be reordered \u2014 owners of MPS40 or MPS50 units should secure a spare before availability ends.<\/p>\n
This power supply is designed exclusively for the Davey ProMatic MPS40 and MPS50 salt water chlorinators, including equivalent models sold under the Monarch Pool Systems name. It is not compatible with other ProMatic MPS models (MPS16, MPS24, MPS36) or the ESR\/ESC series \u2014 always verify your model number before ordering.<\/p>\n
As the electrical heart of your ProMatic system, the power supply must meet precise voltage and current output specifications to protect the electrolytic cell and ensure correct chlorine production. A genuine Davey part guarantees exact fitment, colour-coded connectors for safe installation, and preserves any remaining manufacturer warranty on your system. Non-genuine alternatives risk cell damage and unpredictable chlorine output.<\/p>\n
The power supply connects to the chlorinator cell via a flexible lead with colour-coded connectors fitted to the inside of the cell head. The dedicated pump output socket on the unit must only be used for the pool pump \u2014 never via a double adaptor. Installation must be carried out by a qualified professional in accordance with applicable electrical safety standards (IEC 364-7-702).<\/p>","protected":false},"excerpt":{"rendered":"
