Emerson SP1403 Industrial AC Variable Frequency Drive

Emerson SP1403 Industrial AC Variable Frequency Drive, also listed as the SP1403 Inverter, is an industrial drive with a 1.5–2.2 kW output rating. It accepts 380–480V input at 50–60 Hz and carries the BIN522 designation for this configuration. This VFD varies motor speed by adjusting the output frequency, a core function for controlling equipment powered by electric motors in industrial settings. By converting the supplied fixed-frequency AC power to a variable-frequency output, the SP1403 enables setting different operating speeds for processes without changing mechanical gearing. The SP1403 is part of Emerson's drive family, and the BIN522 reference helps with identification and procurement in service or maintenance workflows. Operators of industrial equipment can reference the BIN522 code for this configuration when planning maintenance or parts replacement, ensuring the correct drive variant is matched to the application.
