MPN #: Ex9VF7
Tired of machines that stall or waste power? The NOARK Electric Ex9VF7 Variable Frequency Drive gives you smooth control and lower energy bills. It changes motor speed with precision, so you avoid sudden stops and overheating. If your equipment needs reliable speed control, this drive is the answer you have been looking for.
Many factories face motor wear because they cannot match speed to load. That problem leads to higher maintenance costs and lost production time. With the Ex9VF7 you get a built-in solution that adjusts frequency instantly. It protects the motor, reduces energy use, and lets you keep the line running without interruptions. The drive works with a wide range of voltages, so you can install it in almost any plant.
The drive fits in conveyor systems that need variable speed. It powers pumps that must follow changing flow rates. It can be used on fans for precise airflow control. It also works with compressors and mixers where torque control is critical. In each case the Ex9VF7 gives you the flexibility to match motor output to real-world demand.

We are retiring PICOPC Products MNHO-073, MNHO-048 and MNHO-043 and they have reached EOL (End Of Life) as we are introducing new products with better technology. We would recommend you to look into MNHO-095. For Untangle, pfSense, OPNsense, Windows 11, Proxmox VE etc. we recommend MNHO-095 whereas for Sophos, Kerio Control and Endian, we would recommend MNHO-069. (A complete list of supported OS can be found in each product's listing)
