709 Description

Short technical summary and product information.

The Hoffman Controls 709-VmA Series electronic controller offers proportional speed control for single-phase motors in variable air volume (VAV) applications. It is compatible with shaded pole or permanent split capacitor (PSC) type motors operating from 120V to 480VAC.

The controller regulates motor RPM based on a 2-10V DC or 4-20mA DC input signal. It features independent adjustments for maximum and minimum speed limits, as well as a separate continuous minimum speed or "drop out" function. This allows for precise motor speed regulation within a desired operating range, ensuring adequate motor ventilation.

Applications include air moving systems using squirrel cage or propeller type fans. The 709-VmA Series can be used in conjunction with components like the 203-5 Flow Transducer and 266-PI Interface for maintaining set airflow through a duct. It may also be suitable for other direct drive motor applications where motors are of the open, drip-proof type.
