TrolMaster Delta-1 VFD Basic Compact Driver for AC Motors - 3-Phase 380-480V - 5HP - 3.7kW

Preset Speed Control for 3-Phase Fan Motors - 5HP Rating

Setting up a drive for a large exhaust or circulation fan usually means entering a long list of parameters before it runs. The Delta-1 arrives with the required parameters preset for the TrolMaster VFD-1 module, so you can connect it and begin controlling motor speed. An RJ45 cable for the link to the VFD-1 is in the box.

This single unit suits growers who run 3-phase AC fans or motors in indoor or commercial cultivation rooms and want speed control through a TrolMaster Hydro-X Pro system. It is not for single-phase motors.

Frequently Asked Questions

Q: Can I use it with a single-phase motor?
A: No. The Delta-1 and the VFD-1 operate only 3-phase fans and motors. Single-phase motors cannot be used with either one.

Q: What does a VFD do?
A: A variable-frequency drive changes the frequency of the power sent to an AC motor. This lets you raise or lower motor speed instead of running it at full speed.

Q: Does it work on its own?
A: It is designed to be used with the TrolMaster VFD-1 module, and the pair can be used with the Hydro-X Pro system. The included RJ45 cable connects the Delta-1 to the VFD-1.

Q: Do I need to program it?
A: This customized version has the required parameters preset for use with the VFD-1 module. It is ready to operate with that module out of the box.

Q: What ambient temperatures can it handle?
A: As an IP20/UL Open-Type unit it is rated for -20°C to 50°C ambient. With the conduit box kit for NEMA 1/UL Type 1, the rating is -20°C to 40°C.
