The controller
modulates the output single pulse width to regulate RPM as determined by a 2–10VDC or 4–20mA DC input signal provided by the customer.
Application
The variable speed
controller is
used for adjustment of motor RPM within a limited range of operating temperatures that assure adequate
operation of the motor. The controller is designed for air moving applications using squirrel cage or propeller type fans.
It may be suitable for other, non air-moving, direct drive motor applications.
