This power supply is based on Velleman K-7200 with voltage adjustment from 0 to 30V (based on one multi-turn potentiometer) and current limiting from 0 to 10A. That values are viewed on a LCD display in which the power supply is equipped.
Additional equipment:
Two DC outputs: 5V and 12V with maximum load of 1A
Three types of measurement
inductance meter from 10nH to 100mH and capacity from 0.1pF to 300nF with automatic switch of the measured element
capacitance meter with ESR factor
frequency meter to 50MHz
Cooling of this device is based on radiators and two small fans controlled from the display board which fulfills the roles of a thermostat, while the side fans work independently with variable depending on the head sink temperature (control system is build on a mosfet transistor and a thermistor).
The power supply is also equipped in a high temperature warning signal exceeded every 2 minutes.
