The NEF30-TPESXY is a voltage regulator module designed by ProMinent, which is used to control the output voltage of various DC power systems. The module is capable of regulating steady-state voltages up to 30V and self-adjusting peak voltages up to 36V. It features a wide range of operating parameters and protection functions, including overvoltage, undervoltage, and overcurrent protections. The module also has an adjustable current limiting feature that helps improve system efficiency and protects against overcurrent and short-circuit conditions. With its robust design, the NEF30-TPESXY can withstand a wide range of environmental conditions and temperatures.
