Central inverter IC7-HVACR

three-phasemodular

Overview
iC7-HVACR is a next-generation variable frequency drive (VFD) designed for energy-efficient HVAC and refrigeration systems in commercial and industrial buildings. It provides modular control, secure connectivity and advanced monitoring to support demanding installations and Industrial IoT integration.

Product summary
The iC7-HVACR family comprises standard drives and an ULH (Ultra Low Harmonic) variant for enhanced harmonic mitigation. Units are suitable for wall-mounted, cabinet-mounted or free-standing installations and offer extended HVACR intelligence with optional sensors, analytics and secure fieldbus connections.

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

• Compact footprint to reduce installation space and cooling load
• Hardware-based cybersecurity (crypto chip) for end-to-end encrypted data transfer and protection against unauthorized access
• HVACR-specific functionality with additional sensors, analytics and future-proof connectivity
• Built-in EMC filter for Categories C1, C2 and C3
• ULH variants delivering very low THDi (< 3–5%) to protect equipment from overheating and malfunction
• Integrated dual Ethernet or RS485 ports supporting BACnet/IP, Modbus TCP, EtherNet/IP, PROFINET RT, EtherCAT, BACnet MSTP and Modbus RTU
• Safe Torque-Off (STO) up to SIL3 / Performance Level e (PLe) as standard
• Multiple onboard sensors with calibration for improved control accuracy
• Back-channel cooling that extracts up to 90% of heat losses from the electrical room to lower HVAC demand
• Compatibility with induction (IM) and permanent magnet (PM) motors
• Integrated condition-based monitoring (CBM) to maximize uptime
• Support for virtual models to simulate drive or converter environments and de-risk upgrades

ULH (Ultra Low Harmonic) variant
The iC7-HVACR ULH variant provides advanced harmonic mitigation for sensitive power networks and installations with strict harmonic limits, improving power quality and equipment lifetime.
