CHV110-055G-4 Variable Frequency Drive CHV110 55.0kW 3-ф/380

CHV110-055G-4 — three-phase frequency inverter from INVT CHV110 series, rated at 55.0 kW active power capacity (nominal output current 110 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 CHV110 — Positioning

INVT CHV110 is a highly specialized series of vector frequency inverters and energy-saving cabinet systems designed for high-precision torque and tension control (Tension Control) in winding/unwinding applications, as well as hydraulic oil-pump energy-saving retrofits for injection molding machines (IMM). The drive supports advanced sensorless and closed-loop vector control modes, delivering smooth speed regulation of spooling units based on the current winding diameter. Featuring built-in reel diameter estimation algorithms and inertia compensation during acceleration/deceleration, the CHV110 series effectively eliminates tension fluctuations even on thin or elastic webs, while optimizing the power consumption of hydraulic pump stations in accordance with mold pressure and flow demands.

Typical Applications:

• Roll Material Winding and Unwinding Systems: Tension regulation in paper, plastic film, and metal foil production with or without dancer/tension sensor feedback.
• Wire Drawing Machine Spoolers: Synchronizing the speed of the receiving spooler with the drawing speed to ensure stable wire winding without breaks.
• IMM Energy-Saving Retrofits: Integration into the mold hydraulic drive control loop to regulate oil-pump performance based on pressure and flow feedback signals.

Competitor Comparison

Unlike the general-purpose Delta C2000 and Danfoss FC-302, the CHV110 inverter offers ready-made hardware solutions as a pre-assembled cabinet with manual or automatic mains bypass switching, along with native compatibility for hydraulic controller pressure and flow feedback signals (0-1A / 0-10V).

Series Limitations:

• The CHV110 series is specifically optimized for winding tasks and cyclic hydraulic loads. For standard multi-pump booster water stations supporting up to 7 pumps with rotation logic, we recommend using the INVT CHV160A series.

Our Practical Experience:

When retrofitting injection molding machines with the CHV110, we confirmed that the integrated analog input filter is crucial for smooth hydraulic pump speed adjustments, preventing mold clamping shocks. For winding systems, calibrating the inertia compensation parameters within the PF group is essential to prevent paper or film sagging during rapid startup and emergency line stops.
