The Johnson Controls VFD68CHH-2C variable frequency drive delivers essential performance for motor control applications. It is rated for an input voltage of 460 VAC ±10%, accommodating fluctuating supply variations. Weighing 3.3 lbs, it fits easily into a variety of installations.
The drive operates effectively within a frequency range of 50 to 60 Hz and features an enclosure rated as UL Type 1 with a fan cooling system. This design allows for robust operation in environments with an operating temperature range of -40 to 50°C. In terms of storage, it withstands temperatures down to -40°C and can operate safely up to 65°C when not in use. Humidity levels can range from 0 to 95% RH without condensation, supporting its functionality in diverse conditions.
The VFD68CHH-2C supports installation at altitudes up to 1000 meters without the need for power derating. It has a current rating of 5 A, suitable for driving motors with a rating of up to 3 hp (2.2 kW). The device is particularly well-suited for 3-phase NEMA Design B motors or inverter-rated motors for enhanced performance.
For added flexibility, users can adjust the PWM carrier frequency between 0.7 kHz and 15 kHz, which helps in matching the drive performance to specific motor requirements. An overload capability of 150% of the current rating is available for brief durations, providing the drive with the ability to manage temporary overload situations effectively. The RS485 communication option offers a reliable interface as an RTU-compliant Modbus slave device, facilitating easy integration into existing control networks.
