The Amrel PD80-7.5D is a programmable linear DC power supply engineered for precision electronic testing, development, and production environments. Delivering 80V at 7.5A (600W), it combines ultra-low ripple and noise with fast transient response and intuitive front-panel control via LCD display. The unit operates in both constant voltage and constant current modes with automatic crossover, eliminating the need for external measurement instruments.
