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. Key Benefits Optimized Condenser Control: Factory-configured for fan speed regulation to maintain stable head pressure. Broad Compatibility: Seamlessly replaces VFD66 series drives with minimal wiring adjustments. Smart Integration: Built-in Modbus RTU capabilities for remote monitoring and diagnostics. Flexible Input Signals: Compatible with ratiometric transducers, sensors, and low-voltage controllers. Industrial Protection: NEMA 1 enclosure with internal cooling fans prevents overheating during high-demand cycles. Common Questions What is the direct replacement for a VFD66BAA-1? The Johnson Controls VFD68CFF-2 is the designated replacement for both VFD66BAA-1 and VFD66BAA-2 models. Can this drive run on a single-phase power supply? No, the VFD68CFF-2 requires a 460 VAC three-phase input to operate three-phase AC induction motors. Does this VFD support P499 transducers? Yes, it is specifically designed to work with Johnson Controls/PENN P499 electronic pressure transducers for automated fan speed modulation. This item is not eligible for free shipping.
