Dramm Variable Speed Fan Controller | AME Power-Station 5A/6A/20A Analog – 6 AMP

The Dramm variable speed fan controller (AME Power-Station) regulates voltage to dial in the exact speed of compatible single-phase fans, running manually or on a 2-10V DC / 4-20mA signal from a climate controller. This greenhouse fan speed controller comes in 5A, 6A, and 20A models with alarm output and power-fluctuation protection. Dramm Variable Speed Fan Controller for Precise Airflow The Dramm variable speed fan controller is an analog voltage-regulating Power-Station that varies the speed of compatible single-phase variable-speed fans by adjusting the voltage they receive. Run it manually to set a fixed speed, or feed it a 2-10V DC or 4-20mA analog input from a climate controller to automate airflow — or shut the controller off — as room conditions change. It comes in 5A, 6A, and 20A models, so you can size the controller to the fan or bank of fans it drives. Greenhouse Fan Speed Controller with Alarm and Failsafe Built for tough electrical conditions, this greenhouse fan speed controller includes protection against extreme power fluctuations and an alarm output that signals events like power loss. If a fault occurs, it auto-reverts to the manual setting to keep fans running instead of dropping airflow — the kind of failsafe that matters when a room full of plants depends on ventilation. Beyond fans, it also regulates electrical heating, bulb or tube lighting, and cooling systems where stable, adjustable voltage is needed. Key Features Analog voltage regulation: Varies the speed of compatible single-phase variable-speed fans. Manual or automated: Run by hand or accept a 2-10V DC / 4-20mA input from a climate controller. 5A, 6A, and 20A models: Size the controller to a single fan or a bank of fans. Alarm output and failsafe: Signals power loss and auto-reverts to manual to keep fans running. Fluctuation protection: Guards against extreme electrical swings; also controls heating, lighting, and cooling.
