Product Overview

The Dooya DT72 LEU-S 1.2-20 is a WiFi-integrated battery motor capable of pulling curtain loads up to 60kg. Operating at a 45W power rating, this unit is engineered for aluminum tracks reaching maximum lengths of 12m. The motor utilizes 24V DC input to deliver a consistent 20cm/s opening speed while maintaining a noise floor of just 20dBA. Designed for longevity, the hardware is rated for 20,000 cycles and includes an IP20 protection rating for residential indoor use. Users can manage the system through a 2.4GHz WiFi connection, enabling voice control via Alexa and Google Home or manual override via the manual bypass feature. The inclusion of a sunlight sensor allows the DT72 LEU-S 1.2-20 to react to 100% solar intensity by closing curtains automatically to protect interiors. Its 165 x 60 x 30 mm dimensions ensure it remains concealed behind the curtain header even on 12m spans. Safety is prioritized with integrated obstacle detection and thermal protection that triggers an automatic stop if resistance is encountered. This motor eliminates wiring constraints in retrofitted smart homes while supporting the heavy 60kg loads typically found in luxury window treatments.

Engineering Analysis

The DT72 LEU-S 1.2-20 utilizes a high-torque 45W DC motor optimized for a 12m track length and 20cm/s linear velocity. Its 20dBA sound profile is achieved through internal sound-dampening mounting that limits vibrations across the aluminum track. Engineering data confirms a 30,000-hour MTBF and a lifespan exceeding 10 years when used within the 60kg weight limit. The 24V DC electrical architecture facilitates a single-phase battery setup with a standby energy-saving mode to extend charge life. For precision, the automatic reset and self-diagnosis features ensure the 12m travel limits are maintained without manual adjustment. The system's 165mm housing incorporates a WiFi module and sunlight sensor logic, processing triggers in under 1 second for instant response. Protection circuits include over-voltage, under-voltage, and anti-jamming sensors to preserve the 45W motor's integrity during 20,000 usage cycles.
