Single/Three Phase Curtain Motor Controller (100-277V)

What the AMC-1 Does

The TrolMaster AMC-1 is a dedicated motor driver for agricultural greenhouse shade and blackout curtain systems. It handles both single-phase supplies ranging from 100–277V at 50/60Hz and three-phase supplies from 207–480V at 50/60Hz, making it compatible with virtually any commercial facility's electrical infrastructure — whether you're running standard US single-phase circuits or a larger three-phase greenhouse distribution panel.

Core motor functions include forward and reverse operation for opening and closing curtain runs, a configurable timeout shutoff to prevent motor overrun, and overcurrent protection that guards against motor damage during a stall or jam event. Both manual override and fully automated scheduling modes are supported, giving operators the flexibility to run curtains on a fixed schedule, trigger them from environmental conditions, or actuate them manually from the GCS-1 panel or the TrolMaster app.

Green-X Integration & GCS-1 Compatibility

The AMC-1 is engineered as a native peripheral of TrolMaster's Green-X greenhouse control platform (GCS-1). It communicates with the GCS-1 base station over RS-485 using a 4-pin waterproof connector, delivering real-time motor status and enabling centralized scheduling alongside climate, lighting, irrigation, and CO2 management — all from a single controller and the free TrolMaster mobile app.

In a fully built-out Green-X system, the AMC-1 works in parallel with the Weather Station Sensor (MBS-WS) so the GCS-1 can trigger curtain position automatically based on outdoor temperature, wind speed, or light intensity thresholds. This closes the loop between the external environment and the physical shade system without manual intervention — exactly what large-canopy greenhouse operators need when managing dynamic light and heat loads across multiple curtain zones.

Build & Environmental Ratings

Greenhouse environments are hard on electronics — humidity, irrigation overspray, and condensation are daily realities. The AMC-1 carries an IP54 ingress protection rating, meaning it is protected against dust and water spray from any direction. Operating ambient temperature range is 32–104°F (0–40°C) with relative humidity tolerance up to 90%, covering standard year-round greenhouse conditions in most North American climates.

The unit ships with a 12-foot RJ12 to 4-pin IP65 connector cable for the RS-485 connection to the GCS-1. The plug-and-play connection architecture means installation does not require custom wiring harnesses or programming beyond parameter entry in the GCS-1 menu — a meaningful time saver during a facility commissioning or retrofit.

Who This Controller Fits

The AMC-1 is the right tool for licensed cannabis and hemp greenhouse operators running TrolMaster's Green-X platform who need automated curtain management tied to their central environmental control loop. It is particularly relevant in light-deprivation greenhouses where blackout curtain timing is critical for photoperiod manipulation, and in glass or poly structures where shade curtains are used to manage canopy temperature and DLI during peak solar hours.

Operators already running the GCS-1 as their primary greenhouse controller can add the AMC-1 as a modular expansion — no additional hub or gateway required. Facilities planning a new build or retrofitting an existing structure with TrolMaster automation should spec the AMC-1 alongside the GCS-1 base station, MBS-GH sensor suite, and any applicable weather station or supplemental lighting controls to achieve a fully integrated, remotely managed grow environment.
