HP / Agilent 6269A 0-40V 0-50A Variable Regulated DC Power Supply

The HP/Agilent 6269A is a variable regulated DC power supply delivering 0–40 V and 0–50 A for demanding laboratory, research, and manufacturing applications. This 2 kW unit combines precise voltage and current control with exceptional line and load regulation, making it suitable for powering sensitive equipment, prototype development, and system validation. Both constant voltage (CV) and constant current (CC) operating modes are supported, with electronic overload protection against short circuits and transient faults.
