It's the next version of 0-25V 0-5A power supply, this one it's closed in a 180x50x240 housing. The main difference is that the radiator is more esthetic.

Version 2
In this one a 2x12 200VA transformer was used.
Version 1:
Version 1.
This power supply is based on a microcontroller. It hasn't got any potentiometer, current adjustment is made by 12 impulse buttons. 8 of those control the tension, one disconnects the output, the next button is used for changing the option between adjusting the current limit and an indication of the actual power consumption. The last 2 buttons are used to smoothly adjust the current and tension.
The R16 resistor should be about 3K instead of 10K!
