Variable Frequency Drive Station for VFD fan speed control

Control Industrial Fan Speed Through a Single Cable

Industrial fans running on a variable frequency drive typically need their own dedicated control path, which usually means separate wiring outside a grower's existing automation system. The TrolMaster VFD-1 closes that gap, connecting to compatible inverters from manufacturers including TECO, Delta, and ABB so a Hydro-X Pro controller can adjust industrial fan speed directly.

No separate power supply is needed for the VFD-1 itself; it draws what it needs through a standard RJ12 phone cable connection to the Hydro-X Pro, which keeps the installation about as simple as any other device station.

Key Features & Benefits

• No Separate Power Supply — runs entirely through its RJ12 connection to the controller.
• Compatible with Select VFD Inverters — works with models from manufacturers such as TECO, Delta, and ABB.
• On-Unit LCD Display — provides easy on-site setup and monitoring.
• Micro-SD Firmware Updates — keeps the station current over time.

Who Should Use the VFD-1 Station

Growers running industrial fans through a compatible variable frequency drive inverter, who want that speed control folded into an existing Hydro-X Pro system, are the intended users of the VFD-1. Confirming the specific inverter model is supported matters before ordering, since compatibility is limited to select inverters.

About TrolMaster

TrolMaster built the VFD-1 to bridge its Hydro-X Pro controller into industrial-scale fan hardware that normally runs on its own separate variable frequency drive, a niche the Sacramento, California company fills for larger commercial installations. Supporting inverters from established manufacturers like TECO, Delta, and ABB keeps that bridge usable across more than one brand of existing equipment.

Frequently Asked Questions

Does the VFD-1 need its own power supply?

No, it draws what it needs through its RJ12 connection to the Hydro-X Pro controller. No separate outlet or transformer is required.

Which inverters work with the VFD-1?

Select models from manufacturers such as TECO, Delta, and ABB; some may require an additional module depending on the specific model. Confirm your inverter is on the supported list before connecting it.

What controller does the VFD-1 require?

The Hydro-X Pro controller. It is not built to pair with other TrolMaster controller models.

How does the VFD-1 connect to my system?

Through a standard RJ12 phone cable, with no additional wiring needed beyond that connection. Installation follows the same process as other TrolMaster device stations.
