The TRK-325D by Zhaoxin is a switched-mode, regulated laboratory power supply. At the output of the PSU, we can regulate the DC voltage in the range from 0 to 32.00V with a resolution of 0.01V. The maximum current efficiency in the entire range of output voltages is 5A. Control of voltage and current values with a digital pulser. In addition, the laboratory power supply has 3 memory cells with voltage and current settings for quick recall. Each change of parameters on the front panel is signaled with an acoustic signal, which can be optionally turned off. The set output voltage is supplied to the terminals only after pressing the OUTPUT key.
