The Davey M1717 is a genuine OEM replacement transformer designed for the ProMatic ESC36pH salt chlorinator \u2014 the legacy Chloromatic controller with integrated pH control. It steps down the 230 V AC mains supply to the lower AC voltage required by the unit’s electronic control board and thyristor circuits, making it the heart of the chlorinator’s power delivery system. This part is available while stocks last and is suited to owners maintaining older ProMatic MPS\/ESC\/ESR installations.<\/p>\n
This transformer is specifically designed for the old-style Davey \/ Monarch ProMatic ESC36pH chlorinator \u2014 the variant featuring a built-in pH control module. It is also referenced as compatible with the broader ProMatic ESC 36\u201348 and MPS 36\u201340 controller range. If you are unsure whether this transformer matches your exact unit, check your controller’s model label before ordering, as different output sizes (ESC16, ESC24) use differently rated transformers.<\/p>\n
The transformer is typically replaced after an electrical fault diagnosis \u2014 for example, when 230 V AC is confirmed at the mains input but no voltage is present at the transformer’s output terminals feeding the control board. Symptoms such as a completely non-responsive controller or repeatedly blown fuses (once the thyristor and PCB have been ruled out) point to transformer failure. Replacing the transformer restores power delivery and brings the chlorinator back into full operation.<\/p>\n
En tant que pi\u00e8ce de rechange d'origine Davey, le transformateur M1717 est con\u00e7u conform\u00e9ment aux sp\u00e9cifications \u00e9lectriques d'origine de la plateforme ESC36pH, garantissant ainsi une tension de sortie correcte, des performances thermiques s\u00fbres et un ajustement physique pr\u00e9cis \u00e0 l'int\u00e9rieur du bo\u00eetier du contr\u00f4leur. Les alternatives propos\u00e9es par des fabricants tiers peuvent ne pas correspondre \u00e0 la tension de sortie requise ou \u00e0 la disposition des bornes, ce qui risque d'endommager la carte \u00e9lectronique. Veuillez noter qu'il s'agit d'une pi\u00e8ce en fin de vie vendue jusqu'\u00e0 \u00e9puisement des stocks \u2014 commandez sans tarder pour \u00e9viter toute indisponibilit\u00e9 future.<\/p>","protected":false},"excerpt":{"rendered":"
