Schneider Electric's ATV310HD11N4A is a variable frequency drive (VFD) designed for efficient motor speed control and reliable performance. Equipped with an integrated heat sink, this unit maintains optimal operating conditions. It is rated for input voltages of 380 to 460 volts AC, accommodating three-phase systems with a tolerance of ±15%.

This unit is capable of delivering a maximum power of 15.0 kW (20.0 HP) under normal duty and 11.0 kW (15.0 HP) for heavy-duty settings. Adjustments to the output frequency range from 0.5 Hz to 400 Hz offer flexibility in application needs. Switching frequency is user-selectable between 2 kHz and 12 kHz, with a factory default set at 4 kHz.

In terms of current, this drive provides a continuous output of 30.0 A for normal duty operations, while heavy duty applications support 24.0 A. When operating at 380 volts, the line current reaches 38.6 A, while at 460 volts, it is at 32.5 A. The ATV310HD11N4A incorporates a Modbus RTU communication protocol via a 2-wire RS-485 setup, permitting addressable connections from 1 to 247 with baud rates between 4800 and 38400 bps.

The drive has one configurable analog input supporting 0–20 mA, 0–10 V, or 0–5 V signals and includes four programmable digital inputs along with two digital/logic outputs. Protection features ensure reliability by safeguarding against overvoltage, undervoltage, overload, short circuits, phase loss, and thermal conditions. This unit is classified with an environmental rating of IP20 and operates effectively within a temperature range of -10°C to +55°C, derating above 55°C to maintain performance.
