Description
The Hoffman Controls 765-ECM Motor Speed Controller is designed to provide manually adjustable, proportional speed control for all sizes and voltages of ECM motors. The 765-ECM is line voltage independent and requires only a 24 VAC supply.
Specification
- Motor Types: ECM (dc brushless) Motors
- Motor Speed: Field Adjustable
- Input Voltage: 24VAC (+20%/-10%)
- Output: 0 – 10 VDC
- 10mA (max.)
- Humidity: 95%, non-condensing
- Ambient: 32° – 158° F
- Dimensions (L x W x H): 4.25″ x 2.40″ x 1.25″
Applications
Variable speed control for ECM motors is accomplished via a 0 – 10 VDC output signal. The manual adjustment range of the control pot provides for a 0-100% motor speed range. The Model 765-ECM Control is capable of sourcing up to 10mA drive current. This will allow for the operation of multiple ECM motors provided the combined maximum drive
current does not exceed 10mA.
