LD series: the professional louvre drive
Slim but powerful
The LD features remarkable power. At up to 1800 N, it opens and closes even the heaviest louvre windows quietly and reliably. In addition to the standard version, an ADVANCE version of the LD is also available with Advanced Communication Bus (ACB) technology. This technology is based on the open Modbus RTU protocol, enabling the drive to be integrated easily into the building management system (BMS). Equipped with ACB technology, the LD offers many technological advantages. For example, it can regulate the opening positions of louvre windows for natural ventilation with one-percent accuracy. In addition to its power and versatility, it is also elegant in its design. Both the 230 V and 24 V versions of the slim LD louvre drive fit unobtrusively into the aesthetics of complex façade structures.
