The Korad KA3005PEA is an Eleshop-only model and is the new and improved version of the popular programmable power supply KA3005P and has an excellent price/quality ratio. The KA3005PS/PE have a better internal design giving them better specifications and more functionality. For example, there is less noise from the fan and a display for the used power. The PEA version also includes an analogue interface which allows you to control the output with a 0-10V signal. It also has the option for a remote off/on function and sensing functionality. The voltage and current can be regulated accurately with an adjustment precision of up to 10mV/1mA. The power supply has a separate switch to turn the output on and off and has 5 memory slots for storing and recalling the output settings. In the table below you can see the difference in specification between the new versions and the original version.
