GE 469-P1-HI-A20-E is a power module that is one of the products of General Electric. Generally speaking, power modules typically have the following functions: power input: Power modules typically accept specific power inputs, such as AC or DC power, to provide the required power supply. Power output: The power module will provide one or more power outputs to supply the power required by other devices or systems. Power management: Power modules typically have power management functions, including voltage regulation, current protection, and energy monitoring, to ensure stable and reliable power supply. Fault detection and protection: Power modules usually have fault detection and protection functions, which can monitor abnormal situations in the power system and take corresponding protective measures, such as overload protection, short circuit protection, etc. Communication interface: Some power modules may provide communication interfaces for data exchange and monitoring with other devices or systems for remote management and control. Reliability and stability: Power modules are typically designed to have high reliability and stability in industrial environments to ensure long-term operation and continuous power supply.

When 469 detects that the motor is running, under a load below the overload pickup set point, or when the motor stops, GE 469-P1-HI-A20-E will start decelerating the stored TCU value to simulate the actual motor cooling process. The TCU decays exponentially at the rate set by the cooling time constant. Usually, the speed of the motor that stops the cooling process is much slower than that of the motor that is in operation, thus providing a cooling time constant setting that reflects the difference in the relay between operation and stop. The TCU lower limit curve for operating cooling is defined by the hot/cold safe stall ratio and the motor load level. The limit of the cooling curve for the lower part of the TCU is 0% and corresponds to the motor at ambient temperature. The start inhibit and emergency restart start inhibit functions can prevent the motor from being available or the motor start monitoring function commands start inhibit when the thermal capacity is insufficient.

Motor start supervision includes the following functions: start interval, hourly start, and restart time. These components of GE 469-P1-HI-A20-E are designed to protect the motor from excessive starting load, which is usually determined by the motor manufacturer in addition to the thermal damage curve. The two elements of mechanical blockage and acceleration time are used to prevent the rotor from accelerating or stalling in situations such as excessive motor damage during abnormal operation. Phase differential protection This function is designed to protect large stator windings and power cable motors. The thermal capacity and motor start used in emergency situations can reset the supervision timer to allow the thermal motor to start.
