40A smoke and heat extraction control unit, 2 ±24V + 12 motor lines

WSC 540 FlexiSmoke™ – Modular SHEV Control Panel (40A)

The WSC 540 FlexiSmoke™ is a powerful and highly flexible modular control panel for smoke and heat exhaust ventilation (SHEV) as well as daily natural ventilation. With a total output current of 40A, it is the ideal solution for medium to large buildings such as schools, sports halls, or industrial facilities. Thanks to its modular design, it can be precisely adapted to individual project requirements and provides maximum safety in accordance with current European standards.

Highlights & Benefits

• Modular flexibility: The control panel consists of two 20A sections and offers free slots for expansion modules to flexibly add motor lines or input/output functions.
• Intuitive operation: An integrated 3.5" LCD touchscreen enables direct configuration, commissioning, and maintenance directly on the device without external software.
• Efficient wiring: Modern bus technology significantly reduces the wiring effort for SHEV control points, smoke detectors, and ventilation switches.
• MotorLink® technology: Supports both ±24V DC standard motors and drives with MotorLink® for millimeter-precise positioning and detailed feedback.
• Certified safety: Complies with EN 12101-10 and ISO 21927-9 (Type D). An integrated emergency power supply ensures operation for at least 72 hours in the event of a power failure.
• Smart building ready: Optional interfaces enable seamless integration into building management systems via KNX or BACnet IP.
