ABB KUC711AE 3BHB004661R0001
Based on the available information, here’s the English information for the ABB KUC711AE module with part number 3BHB004661R0001:
Product Name: Power Supply Control Unit KUC711AE (also referred to as Gate Unit Power Supply or Excitation Drive Module)
Product Description: The ABB KUC711AE (3BHB004661R0001) is a power supply control unit manufactured by ABB. It takes an AC mains voltage, transforms it to a lower level, rectifies it, and smooths it using a capacitor. The unit then performs voltage regulation, typically using a power transistor to maintain a constant output voltage. This type of power supply is described as linearly regulated, known for having a very small residual ripple in the output voltage (in the millivolt range), making it suitable for applications requiring a very exact output voltage. It is specifically designed to provide reliable power to gate units within ABB industrial automation systems, such as the ABB ACS1000 medium voltage AC drive system, and potentially for generator excitation systems.
Product Parameters (Typical):
- Input Voltage Range: 85-264 VAC (some sources mention specific
- voltage based on the unit).
- Output Voltage: 24 VDC (single-phase, according to one source). Specific output voltage to be determined from the unit’s specifications.
- Output Current: Up to 100 A (according to one source). To be determined from the unit’s specifications.
- Output Frequency: 50 kHz (according to one listing, which might be the switching frequency of internal components).
