C power supplies with a high voltage and current output These operate in CC or CV mode within a wide operating range limited only by the output power The operating area of each power supply is determined by the rated output power as well as the voltage and current rating For example the operating area and rated power output for the PSW 30 36 is shown below Voltage PSW 30 36 Operating Area amp 360W rated power Current 12 36 When the power supply is configured so that the total output current x voltage output is less than the rated power output the power supply functions as a typical constant current constant voltage power supply If however the power supply is configured such that the total output current x voltage output exceeds the rated power output the 22 GW INSTEK GETTING STARTED effective output is actually limited to the power limit of the unit In this case the output current and voltage then depend purely on the load value Below is a comparison of the operating areas of each power supply PSW 800V Series Operating Area 900 800 700 600 500 400 300 200 100 Voltage V Current A PSW 250V Series Operating Area 44 432 AS 9 250 200 150 100 50 Voltage V Current A 23 GU INSTEK PSW Series User Manual PSW 160V Series Operating Area PSW 80V Series Opera 24 Voltage V Voltage V 180 160 140 120
