The Korad KA3005PS 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 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. The device 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.
The Korad is programmable via the supplied software and a USB or RS232 connection.
