Controllable down to the millimetre: the louvre drives of the LD Series can be integrated directly into the building management system using the ACB bus technology, based on Modbus. It is also easy to add new functions.

Max. force of pressure and tensile force of 1400 N and 1800 N
Holding force of 5000 N for very large louvre windows
Louvre window drive can be adapted for all common louvre manufacturers (such as EuroLam, Fieger, HAHN, NACO, Schneider + Nölke)
Centrally supported driver position
Developed based on DIN EN 12101-2
D+H LDx-1-ACB can be used for openings for smoke exhaust and for daily ventilation
With BSY+ motor and synchronised electronics controlled via microprocessor
With a sound pressure level of LpA ≤ 45 dB(A), the drive is among the quietest of its class
Corrosion‑protected drive components
Programmable drive functions and different drive parameters
Additional passive and active anti‑trap protection system for the main closing edges with reversing function
Integrated ACB (Advanced Communication Bus) bus interface with Modbus RTU protocol
The drive is integrated directly via open bus communication through the ACB (Advanced Communication Bus), e.g. in a building management system
