The Xantrex XT20-3 is a 60 W programmable linear DC power supply engineered for benchtop and system integration. This quarter-rack unit delivers 0–20 Vdc at 0–3 A with exceptional line and load regulation, very low ripple and noise, and fast transient response. It operates in constant voltage (CV) and constant current (CC) modes with automatic crossover and provides adjustable current limiting from zero to rated output.
