Description

Smart 25A Contactor Water Level Controller | Single- or Three-phase | Tuya Smart Life

The Smart 25A Contactor Water Level Controller is an all-weather, high-power pump automation unit designed for outdoor tanks, boreholes, agricultural irrigation, and industrial sumps. Housed in a weatherproof IP66 enclosure, it combines a heavy-duty 25A AC contactor with liquid-level probe inputs and the Tuya connectivity platform to control large motors without risk of electrical overload.

Product features

• IP66 weatherproof housing: sealed against powerful water jets, torrential rain, heavy dust, and harsh environments, making it ideal for outdoor installation directly at pump sites or water tanks without needing extra protective cabinets.
• 25A contactor: handles inductive motor startup loads up to ~2.2 kW (3 HP). It redirects high voltage and heavy inrush current away from sensitive microcontrollers to prevent contact welding and board failure.
• Remote monitoring: real-time visibility of water percentages or liters via a mobile app, regardless of your location.
• Alerts and notifications: push notifications to your phone for low water, tank is full, or pump malfunction.
