Precise control, simple installation and quiet operation - the ALPHA 5 24 V from Theben is the ideal solution for modern heating systems with low-voltage supply in new buildings and renovations. The Theben ALPHA 5 24 V is a thermoelectric actuator for radiators, heating circuit distributors and systems for individual room or room temperature control. With its operating voltage of 24 V AC/DC, it is particularly suitable for use in energy-efficient heating, air conditioning and ventilation systems with low-voltage control. The integrated "First-Open" function makes initial installation and heating commissioning particularly easy, as the valve remains open during the initial phase. The compact design (44 × 60 × 61 mm) and the flexible installation position - vertical, horizontal or overhead - offer maximum freedom during installation, even in confined spaces. With an actuating force of 100 N and an actuating stroke of 4 mm, the ALPHA 5 24 V ensures precise valve control. It is controlled via a room temperature controller with two-point output or PWM signal. The low switch-on current (<550 mA for max. 100 ms) and a standby power of only approx. 1 W underline the energy-efficient use. Particularly practical for electricians: the simple plug-in installation on standard valve adapters (not included) saves time and reduces installation work. Overvoltage protection and complete protection against actuator damage caused by leaking valves provide additional safety during operation. The IP54 degree of protection allows use even in demanding environments. Users praise the reliable, maintenance-free and virtually silent operation of this valve drive.
