ABB KUC711AE01 3BHB004661R0001

Product Description: The ABB KUC711AE01 (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. However, linearly regulated power supplies have lower efficiency (around 50%) due to energy loss as heat, requiring sufficient ventilation for cooling.

Product Parameters (Typical):

• Input Voltage: AC Mains Voltage (likely 220V AC based on o

• Output Voltage: Lower level DC voltage (specific output voltage to be determined from the unit’s specifications).
• Output Current: (To be determined from the unit’s specifications).
