CHF100-045G-055P-4 Variable Frequency Drive CHF100 55.0kW 3-ф/380

CHF100-045G-055P-4 — three-phase frequency inverter from INVT CHF100 series, rated at 55.0 kW active power capacity (nominal output current 0 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 CHF100 — Positioning

The INVT CHF100 variable frequency drive series is a decade-proven, classic industrial automation solution designed specifically for general-purpose applications where robust operational longevity is paramount. This drive implements highly reliable scalar V/F control algorithms coupled with an optimized current/voltage limit system, successfully preventing nuisance faults under highly dynamic load steps. Featuring a heavy-duty chassis design with independent air ducts (separated cooling zone) and elevated thermal safety margins of the power modules, the CHF100 operates flawlessly in challenging industrial environments of Ukrainian utility plants.

Key Industrial Applications for INVT CHF100

• Industrial Ventilation Systems: Safe control of draft fans, dust extraction blowers, and high-pressure exhaust units utilizing the smooth "speed tracking" function to catch a spinning motor fly-starting.
• Water Supply and Booster Pump Stations: Operation within small multi-pump systems via the integrated analog PID controller for automated pressure or flow regulation.
• Basic Conveyors and Agitators: Cost-effective speed regulation of transport conveyors and mechanical mixers with manual torque boost configurations to overcome initial dry static friction.

What Differentiates INVT CHF100 from Competitors

The INVT CHF100 offers superior dust protection for power PCBs due to its isolated air duct design, and boasts an extended capacitor operating lifetime in the DC link compared to the ultra-compact Danfoss FC-51.

When INVT CHF100 is NOT Suitable

• For drives demanding highly accurate speed holding, maximum dynamic torque response at extremely low frequencies (below 1 Hz), or systems involving permanent magnet motors (PMSM) or servo systems, we recommend current vector drives like INVT GD20 or INVT GD350.

Our Practical Experience with INVT CHF100

We possess vast experience deploying the CHF100 series across municipal boiler systems and woodworking facilities in Ukraine. The drive exhibits excellent tolerance to grid sag down to -15%. The built-in Automatic Voltage Regulation (AVR) function guarantees stable shaft torque even during massive input line voltage fluctuations. Parameter configuration is highly logical, typically requiring only induction motor parameters entry in group P0 and startup command source selection.
