25B-E4P2N104

The Allen Bradley 25B-E4P2N104 is classified as a variable frequency drive (VFD) designed to provide efficient control over three-phase motors. It supports an input voltage of 600V AC, allowing adaptability to various industrial power configurations. The operational voltage tolerance is between -15% and +10%, enabling stable performance under fluctuating supply conditions.

With a motor power capacity of 3 HP or 2.2 kW, the unit delivers an output current of 4.2 A. It incorporates overcurrent protection with a hardware limit rated at 200% and can handle instant fault currents up to 300%. Additionally, the drive's short-circuit rating is specified at a maximum of 100,000 symmetrical Amps, providing robust safeguards against electrical disturbances.

The unit operates effectively at line frequencies of 50 or 60 Hz and includes essential features for enhancing its operational reliability, such as a built-in brake chopper. For user interaction, a keypad with a potentiometer and an LED display facilitates easy adjustment and monitoring of settings. Furthermore, the drive provides a logic ride-through time of at least 0.5 seconds minimally, with a typical duration of 2 seconds, and a rapid power ride-through mode lasting approximately 100 ms. Housed in an open-style enclosure conforming to IP20 standards, the 25B-E4P2N104 is suitable for a variety of applications, ensuring dependable performance in various operational conditions. The carrier frequency can be adjusted between 2 to 16 kHz, allowing further customization for specific motor applications.
