Description
The Delta AFB0405VHA-AR00 (also known as AFB0405VHAAR00) is a compact, high-speed brushless DC axial fan measuring 40 x 40 x 10 mm (1.575 x 1.575 x 0.394 in) designed for space-constrained electronics cooling. Operating on a nominal 5 VDC supply, this single-phase 4-pole motor delivers a high-velocity rotational speed of 8000 RPM, generating 9.254 CFM (15.72 m³/h) of airflow and 0.242 in H₂O (60.4 Pa) of static pressure at an efficient power consumption of 0.55 W. Built with a flame-retardant UL 94V-0 plastic housing and impeller, it incorporates a precision dual ball bearing system that delivers an exceptional L10 operating life of 70,000 hours at 40 °C. Thermal reliability and system safety are ensured through impedance locked rotor protection, reverse polarity safeguards, and a dedicated 3-wire lead harness providing an integrated open-collector rotation detector (RD) locked-rotor alarm signal.
Key Features
- Precision Dual Ball Bearings: Heavy-duty dual ball bearing system ensures exceptional reliability and an extended L10 lifespan of 70,000 hours.
- High-Pressure Airflow Design: High-velocity 8000 RPM impeller generates 9.254 CFM and 0.242 in H₂O to penetrate dense electronic assemblies.
- Integrated Locked Rotor Signal: Features a third open-collector RD alarm lead wire that actively alerts monitoring hardware if rotation halts.
- Flame-Retardant Construction: Precision-molded UL 94V-0 rated housing and impeller meet rigorous international industrial flame and electrical safety standards.
- Comprehensive Motor Protection: Integrated impedance protection prevents motor burnout during 96-hour rotor locks alongside standard polarity-reversal defense.
