TrolMaster Variable Frequency Drive Station for VFD fan speed control in the Hydro-X Pro system

<p>The TrolMaster VFD-1 is a dedicated Variable Frequency Drive Station that connects compatible industrial fan inverters directly to the Hydro-X Pro environmental controller. It provides stepless, automated fan-speed regulation based on live temperature, humidity, or scheduled conditions, allowing large exhaust, recirculation, and dehumidification fans to operate at the required speed instead of simply switching ON/OFF. The VFD-1 is bus-powered through RJ12, so it does not require a separate power supply.</p><p> SKU: VFD-1<br/> Manufacturer: TrolMaster<br/> Compatible Controller: Hydro-X Pro<br/> Power Supply: 12 VDC / 0.2A, bus-powered<br/> Controller Connection: RJ12 phone cable<br/> Control Type: Variable-frequency / stepless fan-speed control<br/> Speed Adjustment: Hydro-X Pro controls fan speed as a percentage of the configured maximum frequency<br/> Control Conditions: Temperature, humidity, or schedule-based conditions<br/> Compatible Inverters:
