Description
The Nidec D1751S24B6CZ-16 is a high-performance DC axial cooling fan designed for industrial thermal management applications including inverter systems, power electronics, control cabinets and other equipment requiring reliable forced air cooling. Manufactured by Nidec, this fan features a compact Ø172 x 51 mm circular frame design with a durable aluminum alloy structure for efficient airflow and mechanical strength.
The D1751S24B6CZ-16 operates with a 24VDC brushless DC motor and provides stable cooling performance with a rated current of 1.8A. The optimized axial airflow design delivers a maximum airflow of 10.2 m³/min (360 CFM) and maximum static pressure of 335 Pa (1.35 inch-H₂O), making it suitable for high-density electronic cooling applications.
Designed for reliable long-term operation, the Nidec D1751S24B6CZ-16 uses a both-side shielded ball bearing system, aluminum alloy die-cast venturi frame and ABS/PBT synthetic resin propeller. The fan features a 2-wire lead connection and integrated overcurrent protection with automatic reset functionality to improve operational reliability.
