Page 11: 5. Operating Instructions
11 5. Operating instructions 5.1 general precautions avoid using the power supply in ambient temperatures above +40° c. Always allow sufficient air space around the venting hole at the rear of the power supply for effective radiation to prevent internal heat build-up. Do not exceed the voltage ratin...
Page 12: Setting Current Limit
12 setting current limit 1) determine the maximum safe current for the device to be powered. 2) temporarily short the (+) and (-) terminals of the power supply together with a test lead. 3) rotate the coarse voltage control away from zero sufficiently for the c.C. Indicator to light. 4) adjust the c...

13 for example, if the load is such that the power supply is operating in the constant voltage mode, a regulated output voltage is provided. The output voltage remains constant as the load increases, up until the point where the preset current limit is reached. At that point, the output current beco...

14 when connected in series, the voltage controls of each power supply exercise control over a 0-30 volt range. Add the led display readings together or connect an external voltmeter across the load to determine the total output voltage. Load current may be monitored from either supply; the readings...

15 when connected in parallel and operating in the constant voltage mode, determine the total load current limit and preset the current limiting for each power supply to half the total load current value. Then when the load is connected, set the voltage controls on the two power supplies for equal v...
