Schneider Electric Variable Frequency Drives (VFDs, VSDs) ATV212HD45N4

The Variable Speed AC Motor Driver, part number ATV212HD45N4, is designed for controlling asynchronous motors with a power rating of 45 kW (60 hp) and operates on a three-phase supply voltage of 380 to 480 V. It features an integrated Class C2 EMC filter and supports a speed output frequency range of 0.5 to 200 Hz, with a nominal switching frequency of 8 kHz. The device can handle a continuous output current of 94 A and a maximum transient current of 103.4 A for up to 60 seconds. This motor driver is suitable for applications such as pumps and fans in HVAC systems. It includes various control profiles, including voltage/frequency ratio and flux vector control without a sensor. The product also offers adjustable acceleration and deceleration ramps, along with multiple communication protocols including Modbus and BACnet. The unit is rated IP21 for protection against solid objects greater than 12.5 mm and dripping water, making it suitable for indoor use. It operates effectively in ambient temperatures ranging from -10 to 40 ¬8C without derating, and can withstand relative humidity levels of 5 to 95% without condensation. The driver is equipped with comprehensive protection features, including overheating, short-circuit, and overvoltage protections. Engineers considering this product should evaluate its compatibility with their specific motor applications and environmental conditions.
