The Allen-Bradley SP-142533 kit is a precharge board kit used with the 1336VT drives from the 1336 series. It has a voltage rating of 460 Volts and an output power rating of 150 Horsepower. The precharge board is used inside the drive and it houses different electrical components. It is a high-quality printed circuit board with symmetrical line voltages. It houses a metal oxide varistor that is used as a surge suppressor for voltage spikes. The precharge board also comes with safety measures for phase to phase and phase to ground protection that meets the IEEE standards. The SP-142533 precharge board is fully compatible with 1336VT adjustable frequency AC drive for regulating and controlling the speed and torque of 3-phase induction motors. The board can be used with both single-phase and 3-phase power sources. 

The Allen-Bradley SP-142533 precharge board kit should not be exposed to outdoors conditions and it should be protected from water sprays. The ambient operating temperature should be set between 0 and 50 degrees Celsius. The board meets all the relevant environmental and industrial standards for safe operation. The SP-142533 board can handle different motor control algorithms including Volts per Hertz control, sensorless vector control, and vector control with Force technology. The 1336 drive that uses the board comes with a human-machine interface module on the front side that acts as an interface between drive and the operators. The interface module supports different languages. The SP-142533 board uses predictive diagnostics to detect faults and errors during the drive operation. The drive produces a 3-phase PWM, adjustable frequency output to supply an adjustable motor speed.
