Johnson Controls VFD68CFF-2 Variable Frequency Drive

As a direct replacement for discontinued VFD66BAA-1 and VFD66BAA-2 models, the Johnson Controls VFD68CFF-2 provides precision three-phase motor speed control for critical HVACR applications. This 460 VAC variable frequency drive is engineered specifically for condenser fan speed control, but remains versatile enough for integration with variable speed pumps and VAV supply fans. Rated at 1 HP (0.75 kW) and 2.2 Amps, the unit features a NEMA 1 fan-cooled enclosure designed for reliable thermal management in commercial environments. It supports P499 electronic pressure transducers and accepts multiple analog inputs, including 0-5 VDC, 0-10 VDC, and 4-20 mA signals. For advanced system monitoring, the VFD68CFF-2 acts as an RS485 Modbus RTU slave device, allowing for seamless communication within a building automation system. The compact PWM carrier frequency is adjustable from 0.7 to 15 kHz, ensuring quiet operation and reduced electromagnetic interference across your motor leads.
