The Allen-Bradley SP-142695 Bus Capacitor Kit is specifically engineered for the 1336 series adjustable frequency AC drives, providing a crucial replacement for each drive's DC bus capacitor bank. Each kit contains one capacitor, essential for filtering the AC component of the supply voltage into a DC wave as part of the IGBT transistor control stage, thus ensuring optimal drive performance. Installation requires careful handling due to electrostatic discharge risks, necessitating the disconnection of power and testing of voltage between capacitor terminals prior to use, with a maximum voltage rating of 600 Volts AC that must not be exceeded.
