This simple VFD remote control adds wireless to your VFD speed control. Using a small, keyfob sized, but highly ruggedized transmitter, we give you control over direction, start/stop, and VFD speed. The VFD radio remote steps through ten speeds, latches the reverse output ON, and has a N/O output for start that is ON in start/run mode. The receiver runs off of 9 – 30VDC (and draws 26 – 34mA if you’re powering the radio from the VFD supply), but you need a minimum of 12VDC to get the full 0 – 10V for the VFD speed controller. The transmitter for the wireless VFD system runs off of internal lithium batteries that recharge over micro USB, and the system provides a nominal 300′ of range.
