Air Performance
Curve range shown in the specification: airflow Q 0-450 m³/h; static pressure ΔP 0-500 Pa.
Air performance is measured according to AMCA 210 / GB 1236, installation category A. Values are valid under the specified measuring conditions and may vary with installation; deviations from the standard configuration must be checked on the installed unit.
Overal Dimmensions
Fan size: 133 × 133 × 110 mm. The outline drawing shows an outer diameter of Ø133 mm, a 110 ±1 mm axial depth, 500 ±20 mm cable length, an inlet ring accessory and M4 mounting with a maximum screw-in depth of 5 mm.
Electrical Connection
U1: positive power supply (+48 VDC); U2: GND; U3: 0-10 V/PWM control input; U4: FG speed output.
The fan provides a speed output signal. The Vfg supply and pull-up resistor are connected by the customer: Vfg = 3-30 VDC; R ≥ 1000 × Vfg Ω.
