The Allen-Bradley SP-154966 is a crucial PSI/Switcher Board designed specifically for the 1395 Digital DC Drive, serving as an interface between the main control board and the power board. This module efficiently converts and regulates an external 115V AC supply into necessary 5V DC and +/-12V DC control voltages, providing essential DC logic power along with three-phase line synchronization signals. Equipped with field current range jumpers, it supports reset, motor thermal, and ECOAST functions, and is compatible with drives ranging from 1–30HP at 240V DC to 2–60HP at 500V DC. Ideal for industrial environments, the SP-154966 operates optimally in clean, dry settings with ambient temperatures between 0 ° and 65 °C and can function within a relative humidity range of 5% to 95% non-condensing.
