Variable Frequency Drive (VFD) · 575V 3-Phase Input · 1 HP, 1.7A, IP20 · Noark Electric EX9VF72T40017B1C
Variable frequency drive for 575V three-phase motor control applications, rated 1 HP with 1.7A current in the Noark Ex9VF7 series. Commonly used for pumps, fans, conveyors, and HVAC equipment where adjustable speed control and energy management are required.
What this product is for
This Noark Ex9VF7 variable frequency drive is used to control the speed and torque of a 575V three-phase motor in industrial and commercial automation systems. It is suited to applications where soft starting, adjustable speed, and process control are needed without stepping up to a larger drive than required.
Use for
- Pumps and booster systems
- Fans and air movement equipment
- Conveyors and material handling
- HVAC motor control
- General motor-driven machinery requiring variable speed
Avoid for
- Single-phase 575V applications
- Installations requiring a higher horsepower or current rating than 1 HP / 1.7A
- Washdown or outdoor locations unless installed in a suitable enclosure
- Applications requiring a factory NEMA 1 enclosed drive unless an enclosure option is added
Best for
Best for electricians, panel builders, and maintenance teams specifying a compact 575V drive for smaller motors in Canadian industrial facilities. It fits jobs where 600V-class supply is standard and panel space matters.
Installed in
Typically installed in control panels, MCC-adjacent equipment sections, OEM machinery, and indoor electrical rooms. The Ex9VF72 frame drawing indicates an approximate enclosure size of 7.6 x 5.4 x 5.9 in. (194 x 136 x 150 mm), which helps with panel layout and clearance planning.
Why this product exists
This drive exists to give controlled motor acceleration, deceleration, and operating speed on 575V three-phase systems while helping reduce mechanical stress and unnecessary energy use in variable-load applications.
Compared with similar products
Compared with across-the-line motor starting, a VFD gives adjustable speed and better process control. Within the Noark Ex9VF7 family, this model is a smaller 575V unit rated 1 HP and 1.7A in a G2 frame, making it suitable where a larger 575V drive would be oversized. As typical guidance, VFDs in this range are commonly selected for variable-torque loads such as fans and pumps, but actual suitability depends on motor data, overload requirements, and local electrical code.
