The UDP3305C DC power supply is a cost-effective programmable control DC power supply with outstanding performance, reliable output and a clear interface. The UDP3305C DC power supply has four independent outputs: two of them are adjustable outputs of 30V / 5A, the other one is a fixed selectable output of 1.8V / 2.5V / 5V / 3A (fine adjustable), and a USB output with 5V / 2A. With the constant voltage (CV) and constant current (CC) modes, short circuit and overvoltage protection features, the instrument can perfectly meet various test requirements.
