Davey – ProMatic ESR Control Box Thyristor for ESR 160/200

This is the genuine Davey replacement thyristor for the ProMatic ESR 160 and ESR 200 salt chlorinator control box. The thyristor is a key power-control component on the electronic board, responsible for regulating the DC current delivered to the electrolytic cell. It is typically replaced when the unit fails to produce chlorine despite the cell being in good condition, or when abnormal alarms or blown fuses point to a fault in the controller’s power stage.

Kompatybilność

This thyristor is specifically designed for the Davey / Monarch ProMatic ESR 160 and ESR 200 salt chlorinator control units — the ESR series without polarity reversal. It is not interchangeable with the ESR 240/300, ESC, or MPS series controllers, which use different components. Always verify your model number on the control box label before ordering.

Dlaczego autentyczność ma znaczenie

Using a genuine Davey part ensures correct electrical ratings and a precise fit on the ESR 160/200 electronic board. Non-genuine thyristors may not match the board’s voltage and current specifications, risking further damage to the controller or erratic chlorine output. As Davey lists this part as available while stocks last, ordering promptly is advisable to secure a like-for-like replacement.

Instalacja

Replacement of the thyristor requires opening the chlorinator control box and working on the electronic board. This work should be carried out by a qualified pool technician or electrician familiar with Davey ProMatic systems. Ensure the unit is fully isolated from mains power before any internal work is attempted.
