Description
The Delta AFB0512HHD-R00 (also known as AFB0512HHDR00) is a high-performance brushless DC tubeaxial cooling fan engineered in a compact 50 x 50 x 20 mm (1.97 x 1.97 x 0.79 in) square form factor. Driven by an efficient two-phase, four-pole motor running on 12 VDC, this cooling fan generates an impressive rated speed of 6400 RPM, delivering 18.30 CFM (31.1 m³/h) of airflow against static pressures up to 0.254 in H₂O (63.2 Pa). Engineered with precision dual ball bearings and an open-frame thermoplastic construction, the unit incorporates an integrated overcurrent locked-rotor shutdown mechanism and a dedicated rotation detector sensor output. Electrical connection is routed through UL 1007 AWG #24 lead wires, providing reliable, continuous thermal management for mission-critical industrial electronics.
Key Features
- Precision Ball Bearings: Heavy-duty dual ball bearing system delivers reliable continuous operation rated for 70,000 hours at 40°C.
- High-Pressure Aerodynamics: Advanced impeller geometry delivers 18.30 CFM airflow and 0.254 in H₂O back pressure within tight enclosures.
- Locked Rotor Alarm: Dedicated third lead provides an automated hardware alarm signal to monitor fan lockup and system faults.
- Auto-Shutdown Protection: Intelligent motor drive circuit limits input current and safely halts rotation during unexpected rotor locking events.
- Industrial Compliance: Fully certified to UL, CSA, VDE, and CE standards with UL Class A rated winding insulation.
