  1. Delta will not guarantee the performance of the products if the application condition falls outside the parameters set forth in the specification.
  2. A written request should be submitted to Delta prior to approval if deviation from this specification is required.
  3. Please exercise caution when handling fans. Damage may be caused when pressure is applied to the impeller, if the fans are handled by the lead wires, or if the fans are hard-dropped to the production floor.

Pulse Width Modulation (PWM) Signal

Pulse Width Modulation (PWM) Signal
  • The frequency for control signal of the fan shall be able to accept a 1 KHz.
  • The preferred operating point for the fan is 1 KHz.
  • At 100 % duty cycle, the rotor will spin at maximum speed.
  • At 0 % duty cycle, the rotor will stop spinning.
  • With control signal lead disconnected, the fan will spin at maximum speed.
  • At DC 12 V , 1 KHz 30 % duty cycle ,the fan will be able to start from a dead stop .

Additional Information

Additional Information
  • The above-mentioned conditions are representative of some unique examples and viewed as the first point of reference prior to all other information.
  • It is very important to establish the correct polarity before connecting the fan to the power source. Positive (+) and Negative (-). Damage may be caused to the fans if connection is with reverse polarity, as there is no foolproof method to protect against such error.
  • Delta fans are not suitable where any corrosive fluids are introduced to their environment.
  • Please ensure all fans are stored according to the storage temperature limits specified. Do not store fans in a high humidity environment. We highly recommend performance testing is conducted before shipping, if the fans have been stored over 6 months
  • Not all fans are provided with the Lock Rotor Protection feature. If you impair the rotation of the impeller for the fans that do not have this function, the performance of those fans will lead to failure.
  • Please be cautious when mounting the fan. Incorrect mounting of fans may cause excess resonance, vibration and subsequent noise.
  • It is important to consider safety when testing the fans. A suitable fan guard should be fitted to the fan to guard against any potential for personal injury.
  • Except where specifically stated, all tests are carried out at relative (ambient) temperature and humidity conditions of 25 ºC, 65 %. The test value is only for fan performance itself.
  • Be certain to connect an "over 4.7 µF" capacitor to the fan externally when the application calls for using multiple fans in parallel, to avoid any unstable power.

Note

Note
  1. All readings are measured after stably warming up through 10 minutes.
  2. The values written in parens, ( ), are limited spec.
  3. Acoustical noise measuring condition:
Noise is measured at rated voltage in free air in anechoic chamber with B & K sound level meter with microphone at a distance of one meter from the fan intake.
