The NA-VC1 is a sophisticated, premium grade 24V DC to 12V DC step-down voltage converter that allows running standard 12V fans in 24V environments such as 3D printers or industrial

and automotive applications. Its neat, ultra-compact and lightweight design makes it easy to integrate in to virtually any environment. Compatible with both 4-pin PWM and 3-pin fans,

the NA-VC1 passes through RPM and PWM signals for speed monitoring and PWM-based speed control (4-pin fans only). At the same time, it adjusts output with input voltage for voltage-

based speed control. Supporting a total output power of 9W, the NA-VC1 can run multiple fans using the optional NA-SYC1 splitter cables or NA-FH1 fan hub. For speed controlling PWM

fans, it can be nicely combined with the optional NA-FC1 fan controller. With a maximum operating temperature of up to 60°C, integrated protection against short-circuits, reverse polarity,

overcurrent and overheating (automatic shutdown) as well as a safety fuse that protects other components in case the unit is mechanically compromised, the NA-VC1 is as bulletproof as a

voltage converter can be. Topped off with CE, UKCA and UL certifications, full compliance with all applicable safety standards as well as Noctua’s 6-year manufacturer’s warranty, it is the

first choice for quality-conscious customers who seek a safe, dependable solution for powering 12V fans in 24V applications.

The NA-VC1 supports both PWM- and voltage-based speed control. PWM signals are passed through and the output voltage scales with the input voltage, e.g. if the input is 12V, the output

will be ~7.5V, allowing a 12V fan to run at a reduced speed:
