The VFD-1 Variable Frequency Drive is explicitly engineered to manage Inverters such as TECO E510, DELTA ME300, and ABB ACS355 (with an FMBA-01 module) and others, when integrated with the Hydro-X Pro controller for the task of adjusting and controlling the velocity of industrial fans within your setup. There's no requirement for a power supply for the VFD-1 unit. A basic RJ12 telephone cable is all you need to connect it to the Hydro-X Pro.
*Firmware Update Information: For upgrading the firmware on TrolMaster's controllers and modules, a Micro SD card of 32GB capacity or less is mandatory.
