The VS3-010-4-N1B-2 from Johnson Controls serves as an AC variable speed drive intended for bypass scenarios. This model is engineered with a robust 10 horsepower rating and a total weight of 63.7 lbs. It operates at a voltage level of 480 VAC with a three-phase configuration, supporting input voltages in the range of 380 to 500 VAC and allowing for a tolerance of -15% to +10%.

With an input voltage frequency of 50-60 Hz, this unit can also sustain frequencies from 45 Hz to 66 Hz if needed. Operating conditions are managed effectively, with temperatures ranging from -10°C (avoiding frost) to a maximum of 50°C, and can reach up to 60°C when operated with torque derating. When storage conditions are considered, it is rated to handle temperatures as low as -40°C and as high as 70°C, making it quite versatile. The humidity tolerance is suitable for non-condensing environments ranging from 0% to 95%.

The drive is designed for installations up to an altitude of 1000 meters and has an output voltage that matches the input, ranging from 0 VAC to 480 VAC. Its operational frequency extends from 0 Hz to 400 Hz, allowing for various speed and control applications. The bypass functionality incorporates two contactor bypasses, which include a disconnect switch and follows the style code N1B. It supports various communication protocols, including BACnet/IP, MS/TP, Modbus TCP, Modbus RTU, and the Johnson Controls SA bus, enhancing its connectivity and integration with other systems.
