Theben Stellantrieb ALPHA 5 24 V

Actuator for radiators, heating circuit manifolds, or individual heating circuits. Operating voltage: 24 V AC/DC. Designed for opening and closing valves in heating, air conditioning, and ventilation technology. Actuation is via a room thermostat with two-point output or pulse width modulation. Inrush current: less than 300 mA for a maximum of 2 minutes. Dimensions: 48.4 x 44.3 x 52.2 mm. Features a "first open function" for easy installation and heating commissioning, with plug-in installation on valve adapter for the most common valve bases and heating circuit manifolds (valve adapter not included in the scope of delivery). De-energised-closed (valve remains closed when de-energised). Offers 100% protection against actuator damage due to leaking valves. Function and adjustment check included. Can be installed vertically, horizontally, or overhead. In the case of overhead installation, special circumstances (e.g., dirty water) can reduce service life. Guaranteed overvoltage protection.
