6.OPERATION INSTRUCTIONS
6-1.Precaution
(1)AC input
AC input should be within the range of line voltage±15% 50/60Hz.
WARNING: To avoid electrical shock, the power cord protective grounding conductor must be
connected to ground.
(2)Installation
The machine itself is a heating source , please don't pile up the machine while operation. Keep the machine from other
heating source at least for 10cm to assure a sufficient space for radiation in order to extend the life of the machine. The heat
sink located at rear of the power supply must have sufficient space for radiation.
CAUTION: To avoid damaging the power supply, don’t use it in a place where ambient
temperature exceeds 40℃.
6-2.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 to have the CC indicator lightened.
(4) Adjust the CURRENT control for the desired current limit. Read the current value on the Ammeter.
(5) The current limit (overload protection) has now been preset. Do not change the CURRENT control setting after this step.
(6) Remove the short between the (+) and (-) terminals and hook up for constant voltage operation.
