VFD-1 VFD Fan Speed Control for Hydro-X Pro

TrolMaster’s VFD-1 is a variable frequency drive interface made for the Hydro‑X Pro controller to automate fan speed. It links the Hydro‑X Pro to compatible inverters (TECO E510, Delta ME300, ABB ACS355 with FMBA‑01), allowing precise adjustment of industrial ventilation fans. The module requires no separate power supply and connects with a simple RJ12 cable. An integrated LCD simplifies setup and a micro‑SD slot supports firmware updates. Designed for environmental control, the VFD‑1 lets Hydro‑X Pro drive ventilation based on room conditions to stabilize airflow, temperature, and humidity. Operating range is 32–122°F at under 90% RH. It is intended as part of the Hydro‑X Pro ecosystem and does not include sensors, functioning solely as the VFD station for fan speed control.
