          GENERAL SPECIFICATION - DC Fans

          1.0 SCOPE
          This specification defines the basic requirements for a DC Brushless Fan manufactured by
          XINRUILIAN SCIENCE & TECHNOLOGY (SHENZHEN) CO. LTD. Wherever if any discrepancy to be
          found between this General Specification and the individual Data Sheet attached to
          samples, information provided in the later should be final.

          2.0 MECHANICAL
          2.1 Dimensions: This device shall have the dimensions as shown in the outline styling
          drawing attached to samples. (All measurements in MM)
          2.2. Material:
          2.2.1 Motor: Brushless DC with permanent magnet motor.
          2.2.2 Impeller: Thermoplastic in black color, rated UL94V-0.
          2.2.3 Housing: Thermoplastic in black color, rated UL94V-0. or aluminium alloy, spray painted black. ( As shown per drawing)
          2.2.4 Bearing System: Sleeve Bearing or Ball Bearing (See data sheet)
          2.3 Leads: UL Type, certified for use at rated temperature and voltage,
          normally +Red/-Black (Different type connectors available on request.)
          2.4 Weight & Packing: As shown per Data Sheet submitted with samples

          3.0 ELECTRICAL
          3.1 Rated Voltage & Power Input: As specified in Data Sheet.
          3.2 Tolerances: Speed +/-10%; Current +20%
          3.3 Dielectric Strength: Applied a 1500VAC, 1mA for one second between housing and lead
          wire(+)
          3.4 Insulation Resistance: More than 500M Ohm between internal stator and lead wire(+)
          measured by 500VDC.
          3.5 Protection: Polarity protected. (Other options available on request)

          4.0 ENVIRONMENTAL
          Unless otherwise specified, when subject to the following conditions, devices within this
          specification shall have no change in appearance, physical dimensions or functionality.
          4.1 Operating Temperature: -10℃ to +70℃ (RH35%~85%)
          4.2 Storage Temperature: -40℃ to +80℃.(RH35%~85%)
          4.3 Acoustical: This device shall have a maximum noise level as specified in Data Sheet submitted with samples, measured 1 meter away from intake side of fan in free air.
          4.4 Life Expectancy: When operating at 25℃, this fan shall have a life expectancy of
          30,000 hours and 50,000 hours respectively for Sleeve Bearing and Ball Bearing
          systems.

          5.0 DEFINITIONS of CHARACTERISTICS
          5.1 Power Input and Speed
          Measured after continuous 30 minutes operation at rated voltage in free air at an
          ambient temperature of 25℃.
          5.2 Noise Level
          Measured in an semi-anechoic chamber with background noise level below 18+/-1dBA.
          The fan to be running in free air with microphone at a distance of one(1) meter from
          the intake side of fan.
          5.3 Air Flow
          Measured by a double chamber. The values are recorded when the fan speed is
          stabilized at rated voltage and 0 static pressure.
          5.4 Static Pressure
          Measured at rated voltage with 0 air flow at an ambient temperature of 25℃.

          6.0 SAFETY APPROVALS
          All Xinruilian DC fans are approved and licensed for selling by UL/CUL; TUV; CSA; CE.
