Combining the NV-FH2 8 channel PWM fan hub with the NV-PS1 230/115V 24W power supply, the NV-SPH1 powered hub set is the ideal solution for powering up to eight 12V fans off the mains for home, office or multi-purpose ventilation applications. For stepless speed control of PWM fans, the optional NA-FC1 controller can be connected to the 4-pin input of the NV-FH2, and if more than eight fans are required, additional NV-FH2 hubs can be daisy-chained. Both the NV-FH2 and the NV-PS1 carry CE, UKCA and UL certifications, are fully compliant with all applicable safety standards and come with Noctua’s 6-year manufacturer’s warranty. In short, the NV-SPH1 is a complete premium set for powering multiple 12V fans from wall outlets and can be easily expanded with the optional NA-FC1 controller as well as additional NV-FH2 boards.NV-FH2 fan hubThe NV-FH2 is a premium-grade 8 port fan splitter board that can take power via its 5.5mm barrel connector input and use its 4-pin PWM input for RPM monitoring and PWM control. With its removable clip-on cover, magnetic fixture and extra screw holes, it’s highly flexible and right at home in just about any application.NV-PS1 power supplyThe NV-PS1 is a high quality 24W power supply with wide-range input (115/230V) and socket adaptors for EU, UK and US. With its excellent efficiency and minimum standby power consumption, it’s a perfect choice for powering 12V fans from wall outlets.Ideal combination with the NA-FC1 fan controllerThe NV-SPH1 set is ideal for controlling multiple fans using the optional NA-FC1 controller. Thanks to a reverse-power design on the 4-pin input of the NV-FH2, the NA-FC1 can control the connected fans even if the hub is powered via 5.5mm barrel connector and if there is no other connection or input on the 4-pin interface.Safety certificationsBoth the NV-FH2 and the NV-PS1 have been carefully tested for product safety and EMC compliance. Carrying CE, UKCA and UL certifications and meeting all applicable standards (EN 62368-1, EN 55032), they are safe, quality devices through and through.
