SP-140578

The SP-140578 kit is a transistor kit in the 1336 spare parts and replacement parts catalog from Allen-Bradley/Rockwell Automation. This specific kit has been designed to operate with some of the adjustable frequency drives from the Allen-Bradley 1336 series. These drives are used with variable speed motors and their main function is to control the speed, acceleration, and deceleration of motors by modifying their frequency. The Allen-Bradley/Rockwell Automation SP-140578 transistor kit does not come with any kind of housing since it is meant to be installed inside the enclosure of the host drive. Although the transistor will not be exposed to open air, it is recommended that the environment that it is used in be cooled and ventilated to avoid overheating, extend the life of all the parts, and prevent damage during operations. Cooling equipment must be installed independently by users.

The Allen-Bradley/Rockwell Automation SP-140578 transistor kit is sensitive to corrosion and electrostatic discharge or ESD. It is recommended to perform its installation in a controlled environment where the area has been prepared to avoid any contact with an electrostatically charged device. ESD can cause damage to this transistor kit even before it is put into operation, which is why static control is essential. The Allen-Bradley/Rockwell Automation SP-140578 transistor kit needs to be installed in a system with other transistors (6 per drive). It can operate with drives with voltage ratings between 380 and 460 Volts AC and an output rating of 218 to 290 Amps. Transistors are in charge of amplifying electrical signals between different equipment. It can operate in a temperature range of 0 to 40 degrees Celsius and a humidity range of 5 to 95 percent.
