Overview
Whatever your system ambition, iC7-HVACR can fulfill it. iC7-HVACR is the next generation variable frequency drive (VFD) for HVAC applications, engineered to deliver reliable performance and energy-efficient control in commercial HVACR systems. The modular control platform enables flexible functional expansion and simplifies upgrades of existing installations.

ULH variant
The iC7-HVACR ULH variant is an ultra low harmonic HVAC drive that sets a new benchmark for harmonic mitigation, ensuring cleaner power and prolonged equipment life.

Supply voltage and power range
Standard drives: 3 x 380-480 V AC — 1.1 – 710 kW
Ultra low-harmonic (ULH) drives: 3 x 380-480 V AC — 22 – 160 kW

Key features

• Highly compact design saves space and reduces cooling requirements in energy-efficient HVAC systems
• Hardware-based cybersecurity with onboard crypto chip for encrypted data transfer and protection against unauthorized access
• HVACR-specific intelligence with additional sensors, analytics and connectivity options
• EMC compliance with built-in EMC filter (Categories C1, C2 and C3)
• Ultra low-harmonic (ULH) variants provide harmonic mitigation with very low THDi (< 3–5%), protecting equipment from overheating and malfunction
• Integrated dual Ethernet or RS-485 ports; supports BACnet/IP, Modbus TCP, EtherNet/IP, PROFINET RT, EtherCAT, BACnet MSTP, Modbus RTU
• Safe Torque-Off (STO) up to SIL3 / Performance Level e (PLe) as standard
• Numerous integrated sensors and calibration functions to improve control accuracy
• Integrated condition-based monitoring (CBM) for predictive maintenance and maximized uptime
• Efficient heat management using back-channel cooling to remove up to 90% of electrical-room heat losses
• Compatible with induction (IM) and permanent magnet (PM) motors
• Supports virtual models to simulate drive or converter environments for faster development and reduced risk

Applications and installation
Optimized for wall-mounted, cabinet-mounted or free-standing installation. Core component for energy-efficient HVAC systems in commercial buildings and for installations with strict power quality or harmonic limits.
