100 HP 230 V Variable Frequency Drive · Delta Electronics VFD750C23A21
Delta Electronics VFD750C23A-21 is a C2000 series variable frequency drive rated 100 HP (75 kW) at 230 VAC, 3-phase, with 255 A heavy-duty output. It is commonly used for pumps, fans, conveyors, and other industrial motor control applications where adjustable speed, torque control, and integration options matter.
What this product is for
This variable frequency drive (VFD) is used to control the speed and torque of 230 VAC, 3-phase motors in industrial systems. It fits applications such as pumps, fans, conveyors, process equipment, and other machinery that benefit from adjustable motor speed and controlled acceleration and deceleration.
Use for
Use for 100 HP (75 kW) motor control on 230 VAC, 3-phase systems where you need variable speed operation, process tuning, and reduced mechanical shock during starts and stops. It is suitable for both constant torque and variable torque applications, depending on programming and motor setup.
Avoid for
Avoid for single-phase supply, line-voltage switching in place of a proper drive, or installations that require a higher enclosure rating than IP20 without a suitable cabinet. Also avoid assuming all motors and loads can use the same settings; commissioning should match the motor data, load type, and site conditions.
Best for
Best for industrial panels and machine retrofits where electricians, integrators, and maintenance teams need a 230 VAC, 3-phase drive with broad control modes, communication options, and heavy-duty motor control capability.
Installed in
Typically installed in electrical control panels, MCC-adjacent enclosures, OEM machinery, and industrial process systems. The listed enclosure rating is IP20, so it is generally installed inside a suitable cabinet for protection and code-compliant integration.
Why this product exists
This drive exists to give precise motor speed control, starting torque management, and process efficiency on larger 230 VAC, 3-phase motor systems. In many applications, a VFD can reduce inrush stress and improve control compared with across-the-line starting. Actual energy savings and performance depend on load profile, programming, motor compatibility, and installation conditions.
Compared with similar products
Compared with basic VFDs, the Delta C2000 platform is positioned for more advanced industrial motor control, with support for multiple control methods, higher integration capability, and broader application flexibility. This model is rated 100 HP heavy duty at 255 A, includes a built-in DC reactor, and is intended for 230 VAC, 3-phase systems. It does not include a built-in EMC filter or built-in braking chopper on the referenced listings.
