Description

D+H VCD 203 Chain Actuator – 24V Window Automation Drive (200N, 250mm Stroke)

The D+H VCD 203 Chain Actuator is a high-quality 24V DC electric window drive designed for reliable automation of façade windows, roof windows, and ventilation flaps. Built by leading manufacturer D+H, this compact yet powerful chain actuator is ideal for projects requiring smooth daily ventilation control, improved indoor air quality, and dependable performance in commercial or residential buildings.

With a thrust force of 200N and a stroke length of 250mm, the VCD 203 is perfectly suited for automated natural ventilation systems, conservatories, rooflights, and window opening applications where controlled airflow and safety are essential.

Key Features & Benefits

Reliable Microprocessor-Controlled Operation

The VCD 203 actuator includes advanced motor electronics controlled via an integrated microprocessor. This ensures consistent performance, smooth movement, and precise window positioning during opening and closing.

TMS+ Tandem Safety Function

For larger window sashes requiring two actuators, the VCD 203 features the TMS+ tandem safety function, allowing two drives to operate safely on a single sash. Any programmed stroke adjustment is automatically transmitted to the tandem drive, ensuring synchronized operation.

Programmable Stroke Adjustment

The actuator stroke can be easily programmed using a magnet, allowing installers to tailor the opening distance to suit specific ventilation or building requirements. This flexibility makes it suitable for a wide range of window types and configurations.

Enhanced Safety with Closing Edge Protection

The VCD 203 includes passive closing edge protection, reducing closing speed to 5mm/s in the CLOSED direction. This feature improves safety by helping prevent trapping hazards and supporting safer operation in occupied environments.

Optional Burglary-Resistant Locking Force

For added security, the actuator offers an optional burglary-resistant effect with a maximum locking force of up to 4000N, helping to improve window resistance against forced entry when closed.

Simple Installation & Connectivity

The actuator is designed for straightforward installation, featuring plug connector wiring for quick and secure connection. Programmable drive functions and adjustable parameters provide further flexibility for integration into building management or ventilation control systems.

Compliance & Important Guidance

Where Automatic Opening Vent (AOV) systems are required, ensure windows are tested in accordance with BS EN 12101-2 and carry the necessary CE marking. Inbuild Online supplies a range of D+H actuators compliant with BS EN 12101-2, and the window frame manufacturer should confirm compatibility as part of the CE certification process.

Ideal Applications

The D+H VCD 203 Chain Actuator delivers a trusted combination of safety, programmability, and robust window automation, making it an excellent choice for modern ventilation and façade control systems.

D+H VCD 203 Chain Actuator, 24V, 200N, 250mm

£135.71 excl. VAT

D+H VCD 203 Chain Actuator – 24V Window Automation Drive (200N, 250mm Stroke)

The D+H VCD 203 Chain Actuator is a high-quality 24V DC electric window drive designed for reliable automation of façade windows, roof windows, and ventilation flaps. Built by leading manufacturer D+H, this compact yet powerful chain actuator is ideal for projects requiring smooth daily ventilation control, improved indoor air quality, and dependable performance in commercial or residential buildings.

With a thrust force of 200N and a stroke length of 250mm, the VCD 203 is perfectly suited for automated natural ventilation systems, conservatories, rooflights, and window opening applications where controlled airflow and safety are essential.

Key Features & Benefits

Reliable Microprocessor-Controlled Operation

The VCD 203 actuator includes advanced motor electronics controlled via an integrated microprocessor. This ensures consistent performance, smooth movement, and precise window positioning during opening and closing.

TMS+ Tandem Safety Function

For larger window sashes requiring two actuators, the VCD 203 features the TMS+ tandem safety function, allowing two drives to operate safely on a single sash. Any programmed stroke adjustment is automatically transmitted to the tandem drive, ensuring synchronized operation.

Programmable Stroke Adjustment

The actuator stroke can be easily programmed using a magnet, allowing installers to tailor the opening distance to suit specific ventilation or building requirements. This flexibility makes it suitable for a wide range of window types and configurations.

Enhanced Safety with Closing Edge Protection

The VCD 203 includes passive closing edge protection, reducing closing speed to 5mm/s in the CLOSED direction. This feature improves safety by helping prevent trapping hazards and supporting safer operation in occupied environments.

Optional Burglary-Resistant Locking Force

For added security, the actuator offers an optional burglary-resistant effect with a maximum locking force of up to 4000N, helping to improve window resistance against forced entry when closed.

Simple Installation & Connectivity

The actuator is designed for straightforward installation, featuring plug connector wiring for quick and secure connection. Programmable drive functions and adjustable parameters provide further flexibility for integration into building management or ventilation control systems.

Compliance & Important Guidance

Where Automatic Opening Vent (AOV) systems are required, ensure windows are tested in accordance with BS EN 12101-2 and carry the necessary CE marking. Inbuild Online supplies a range of D+H actuators compliant with BS EN 12101-2, and the window frame manufacturer should confirm compatibility as part of the CE certification process.

Ideal Applications

The D+H VCD 203 Chain Actuator delivers a trusted combination of safety, programmability, and robust window automation, making it an excellent choice for modern ventilation and façade control systems.
