The Schneider Electric ATV21HD15N4 is an adjustable frequency drive suitable for three-phase applications. With a power rating of 45 kW running at 500 V, it can achieve a commendable maximum horse power rating of 60 hp when connected to 575 V systems. This drive is designed to handle supply voltages ranging from 500 V to 690 V, functioning efficiently while tolerating voltage fluctuations between -15% and +10%.

When operating at 600 V, the unit draws a line current of 57 A, which is significant for its power class. In addition, it features a Level 3 EMC filter aimed at mitigating electromagnetic interference, thereby enhancing its robustness in industrial environments. The assembly style is equipped with a heat sink, ensuring effective thermal management during operation.

The ATV21HD15N4 can withstand a maximum prospective line fault current (Isc) of 22 kA for three-phase applications. It is capable of managing transients with currents up to 81.6 A for a duration of 60 seconds. The nominal switching frequency is set at 2.5 kHz, although it can be adjusted within the range of 2.5 to 4.9 kHz based on application requirements.

Furthermore, the drive supports asynchronous motor control using a voltage-to-frequency ratio for energy saving, utilizing a quadratic U/f method. For synchronous motors, it employs vector control without sensors, ensuring optimized operation.

In terms of communication capabilities, this device supports the CANopen and Modbus protocols, providing flexibility for integration into various control systems. Additionally, it offers an option card that supports a wide array of communication protocols, including APOGEE FLN, BACnet, DeviceNet, and more, catering to diverse networking needs across different applications.
