CHV160A-185-4 Variable Frequency Drive CHV160A 185.0kW 3-ф/380

CHV160A-185-4 — three-phase frequency inverter from INVT CHV160A series, rated at 185.0 kW active power capacity (nominal output current 340 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 CHV160A — Positioning

INVT CHV160A is a specialized multi-pump variable frequency drive designed for high-efficiency and energy-saving municipal water supply, wastewater, district heating, and HVAC systems. The drive features advanced built-in multi-pump cascade logic, enabling intelligent coordination of up to 7 pumps (supporting both auxiliary contactor switching and cascade frequency control of each individual unit) without requiring external PLCs. The series is optimized for light-duty pump and fan applications (P rating) and features specialized pipeline protections against water hammer, leakage detection, and automatic duty running rotation to prevent uneven wear of the pumping machinery.

Typical Applications:

• Municipal Water Booster Stations: Stabilizing pressure in main distribution pipelines, automatically staging additional pumps during peak hours, and activating sleep mode during low-demand night hours.
• Industrial Cooling Towers: Precise temperature control of cooling fluids by smoothly coordinating fan speeds and circulation pump cascade staging.
• Fire Pump & Sewage Pump Stations: Automatic backup pump staging upon main pump failure, dry-run protection, and monitoring of check valve blockages.

Competitor Comparison

Compared to Delta CP2000 and Danfoss FC-202, the CHV160A inverter provides the most scalable out-of-the-box cascade configuration without requiring optional pump control cards. This substantially reduces the overall investment cost of the water automation system.

Series Limitations:

• CHV160A is designed exclusively for pump and fan duties with an overload rating of up to 120%. For heavy-duty industrial applications requiring high starting torque (such as ball mills or mixers), please use the flagship INVT CHV100 series.

Our Practical Experience:

Through numerous installations of CHV160A in public utilities, we verified that the soft pipe filling function successfully eliminates the danger of water hammer when restarting the system after maintenance. The integrated real-time clock (RTC) allows engineers to set distinct target pressure levels for day and night cycles directly in the drive parameters. We recommend connecting a 4-20mA pressure sensor to the AI2 input and configuring the sensor-loss fault action to guarantee continuous water supply.
