The Allen-Bradley 1336-RFB-30-A4 drive filter is a part that provides a 3-phase, Pulse Width Modulated (PWM) adjustable frequency power output which in turn offers an adjustable motor speed. It has a voltage tolerance of -10% of minimum and +10% of maximum and its frequency tolerance is 48-62 Hz. It has input phases of 3-phase input power which offers the total rating for all drives. Single-phase operation can be achieved for A & B frame drives at a 50% derating in output. As for the displacement power factor, A1-A3 frame drives is 0.8 standard or 0.95 with the optional inductor; A4 frame & above is 0.95 standard. Its efficiency is 97.5% at rated Amps.
