Kikusui PAD70

The Kikusui PAD70 is a linear regulated DC power supply engineered for electronics testing, development, and long-term aging applications. It delivers stable, adjustable DC voltage and current outputs with constant voltage (CV) and constant current (CC) modes, making it suitable for powering and characterizing electronic circuits across diverse voltage and current requirements. The unit features dual-mode operation, integrated overvoltage protection, and precision analog controls for fine adjustment of output parameters.
