CHF100A-090G-110P-4 Variable Frequency Drive CHF100A 90.0kW 3-ф/380

CHF100A-090G-110P-4 — three-phase frequency inverter from INVT CHF100A series, rated at 90.0 kW active power capacity (nominal output current 176 A) for electrical grids with 3-phase 380V supply voltage. The VFD supports sensorless vector control (SVC) and scalar V/F control, delivering smooth motor speed adjustments and dynamic torque response. The device features IP protection standard, integrated EMC filter, and built-in Modbus RTU RS-485 communication interface.

Typical Applications:

• Industrial conveyors, mixers, extruders, and packaging machine drive systems.
• HVAC fans and automated pump systems utilizing built-in PID controller for constant pressure hold.

Please Note: Perform motor autotuning (rotating or static) before first system startup. When installing motor cables longer than 50 meters, an output reactor (du/dt filter) is highly recommended to protect motor winding isolation from voltage spikes.

INVT CHF100A — Positioning

The general-purpose INVT Goodrive100A (CHF100A) variable frequency drive series marks a legendary milestone in the brand's control technology, featuring an advanced dual-processor DSP architecture. This drive seamlessly integrates versatile scalar V/F control with high-precision Sensorless Vector Control (SVC), making it equally suitable for standard centrifugal fan loads and highly demanding dynamic machinery applications. Its intelligent hardware layout, incorporating dual G/P power ratings, integrated DC reactors standard across mid-range models (18.5 kW to 90 kW), and high operating temperature margins, guarantees maximum equipment availability.

Key Industrial Applications for INVT CHF100A

• Cyclic Industrial Automation Processes: Executing automated multi-speed cycles on woodworking, stonecutting, or packaging machines using the built-in 16-step Simple PLC and highly configurable analog interfaces.
• Water Supply and Commercial Heating: Driving heavy circulation pumps with stable pressure maintenance utilizing the integrated PID controller, automated sleep/wake logic, and dynamic energy-saving algorithms.
• Medium-Duty Material Handling and Conveyors: Running belt conveyors, bucket elevators, or industrial hoists because of its high starting torque capacity (150% at 0.5 Hz in SVC vector mode) and fast current limit limits.

What Differentiates INVT CHF100A from Competitors

Compared to Delta VFD-B, the CHF100A series exhibits higher tolerance to voltage fluctuations in rural areas and offers more granular auto-torque boost configuration parameters.

When INVT CHF100A is NOT Suitable

• As the CHF100A is a legacy series and is discontinued, for new installations demanding maximum modern energy efficiency or high-speed fieldbus connectivity (EtherCAT, Profinet), we highly recommend upgrading to the modern INVT GD200A series or the state-of-the-art INVT GD350 drives.

Our Practical Experience with INVT CHF100A

We have successfully deployed over a thousand CHF100A drives throughout industrial plants in Ukraine. The drive has earned a legendary reputation for durability because of its thick steel backplate framing in larger sizes and massive heat-sink engineering. When transient load surges occur, the internal current-limiting algorithm smoothly dials back output frequency instead of immediately tripping on overcurrent faults (such as OUT1 or OUT2), keeping production lines running without expensive unexpected shutdowns.
