This is UTP3315TFL Variable power supply that can provide 0 to 30v and 0 to 5a. The dc power supply adjustable for UTP-3315TFL has an over-current constraint, which means that the output owing to the current must obey and restrict it to the fixed value by reducing its output voltage. This linear dc power supply safety is very functional for professionals and students in laboratory experiments.
