The 9G1224H1D01 is a San Ace 120 (9G) series DC fan designed for cooling electronic equipment. It operates on a rated voltage of 24V DC, with a functional voltage range of 14V to 27.6V DC, and draws a rated current of 0.22A. At its nominal voltage, the fan achieves a speed of 2600 min⁻¹ while producing a sound pressure level of 39 dB(A). Built with a durable plastic frame and impeller on a dual ball bearing system, it is designed for a wide operating temperature range of -20°C to +70°C. The inclusion of an open-collector lock sensor makes it ideal for applications requiring high reliability and performance monitoring, such as industrial controls, servers, and telecommunications hardware.
