Core Technical Specifications:

Appearance & Core Structure:

• Physical Dimensions: Standard 3010 form factor (30mm × 30mm × 10mm), a micro axial cooling fan with compact size, perfect for installation in space-limited small equipment.

• Electrical Parameters: Rated voltage DC 24V, rated current 0.10A, with a DC brushless motor for long service life and stable operation.

• Wiring Design: Equipped with a 4-wire PWM speed control interface (red, black, yellow, green wires), supporting intelligent speed adjustment via PWM signals. It can automatically adjust fan speed based on device temperature for temperature-controlled energy saving and noise reduction.

• Certifications & Origin: CE and RoHS certified, made in China, meeting global market regulatory requirements.

Highlights:

​

• Wire type: 4-core PWM electronic wire

• Conductor: Stranded tinned copper wire, flexible, anti-break, good conductivity

• Insulation material: High temperature resistant PVC, flame retardant, durable

• Standard wire length: 150mm, customizable length available

• Wire function definition

1. Red wire: 24V positive power
2. Black wire: GND negative power
3. Yellow wire: FG speed signal output
4. Green wire: PWM speed control signal input

Important Notes:

• Please confirm the connector model, pin sequence and wire gauge before installation to avoid wrong connection, short circuit or equipment damage.

• Avoid using the wire harness in over-current, over-voltage or high-temperature exceeding the rated working range, to prevent wire heating and safety risks.

• Keep the connector away from water, dust, oil and corrosive environments to ensure long-term stable conductivity and avoid poor contact.

• Do not bend or squeeze the wire sharply for a long time; reasonable wiring protection can extend the service life of the harness.For drone and flight model applications, check the locking buckle condition before flight to ensure firm connection and prevent mid-air disconnection.
