MANUFACTURING FEATURES
• Flexible polyurethane coupling flange with fiberglass fabric to avoid possible vibrations to the installation.
• 160 mm width and supplied with 2 fixing clamps.
• Certified according to the European standard EN 12101-3 400ºC/2h. Fire classification: M0.
Switch for ATEX environments. Suitable for zones 1-2 (gas) and 21-22 (dust), index protection IP65. Manufactured in aluminum alloy and RAL 7000 gray finishing coat. External screws in stainless steel. Control on the front. Tensions up to 690V. According to directive 2014/34 / UE (ATEX).
Flexible joint made of PVC
PVC/PP Gravity damper
Manual adjustable damper made of PVC/PP
MANUFACTURING FEATURES
• Specially designed for speed frequency control in ventilation applications.
• Ultra compact, simple operation and wide range of functions.
*Dial panel incorporated. Optional EMC filter.
Certifications: CE/UL/CSA/EN/GOST/CCC.
Protection index IP20.
The selection of SFC frequency drive speed controller must be made based on the maximum intensity absorbed by the fan to be regulated. The powers (kW) and the intensity for constant load refer to the normal duty (150% overload for 60 seconds). The intensity for quadratic load admits an overload of 110% during 60s.
SFC 230: Entrance 230V I, exit 230V III
SFC 400: Entrance 400V III, exit 400V III
EMC filter incorporated for models from 47A (included)
*Lineal load rated current
**Quadratic load rated current
