Regulated & Linear: Made by wire isolation transformer as the voltage conversion, Linear power supply is quiet, no noise and costs higher while switching power supply is a transistor conversion which gives much noise and interference, but low cost and low stability.

4-Digital Display & High Precision: Equipped with 4-Digit LED display allows you to see the voltage and current in an easy-to-read interface. Variable to as precise as 0.01V and 0.001A.

Safety Protection: Featuring systems for short-circuit protection, overload protection, and reverse polarity protection, UTP3315TFL-II is a highly reliable bench power supply.

Portable & Easy to Use: A small footprint of 4.1" x 6.5" x 9.8" makes this power supply easy to carry. Separate keys to avoid misoperation.

Multi Applications: Regulated output of 0-30V and 0-5A, Linear power supply is a perfect kit with oscilloscope and function generator. It is an ideal tool for DIY electronics hobbyists, institutions of higher education, enterprise production lines, household appliance repair companies.

A very nice bench power supply.

This is a very nice bench top power supply, yet it is small enough to carry temporarily to other locations. The voltage and current ranges cover a lot of situations. The coarse and fine adjustments for both voltage and current make setting exact values very easy. Plus being able to run in constant voltage or constant current makes it applicable in different situations.

Power suppy

This is a pretty great power supply it comes with everything you need and best of all if you save your points you can get it at an unbelievable price. If there is anything wrong with it I would say I wish it had double hook ups that the reason for only 3 stars. But other then that it's perfect.
