# AutomationDirect SV2A-4300

Hardware · `SV2A-4300` · verification: source checked

The SV2A-4300 is a SureServo2 servo drive rated 3 kW with a 460 VAC three-phase input and a 9.9 A rating. It controls torque, velocity and position and produces SVPWM output, closing the loop on a 24-bit encoder. One RS-485 (RJ45) port provides Modbus RTU or Modbus ASCII slave communication at up to 115.2k baud.
