Dramm Speed Controller for Variable-Speed Fan Control
The Dramm Speed Controller (AME Variable Power-Station) is an analog voltage-regulating controller built to dial in the exact performance you want from compatible variable-speed single-phase fans.
AME Variable Power-Station with Analog Input Integration
It can run as a simple manual controller or accept an analog input (2–10V DC or 4–20mA) from a climate controller to automate fan speed or shut the controller off via signal.
Reliable Voltage Regulation with Alarm Output
Designed to handle tough electrical conditions, it includes protection against extreme power fluctuations plus an alarm output for events like power loss. If a failure occurs, it auto-switches to the manual setting to help keep fans operating instead of dropping your airflow. It’s also suitable for controlling electrical heating, bulb/tube lighting, cooling systems, and other voltage-regulated devices where stable, adjustable output matters. Available options: 5AMP, 6AMP, and 20AMP.
