5-1 Precaution
1 AC input of DC power supply should be within the range of line voltage 220
±

％
50Hz.110

60Hz
2 To avoid electrical shock, the power cord protective grounding conductor must be connected to ground.
3 Do not use the unit in a place where ambient temperature exceeds 40
C
. The heat sink located at rear of
the supply must have sufficient air space for radiation.
4 This unit is a float DC power supply. lf the output have to connected to ground, please short the
"+"
or -
terminal to
"
GND
"
.
5-2 Setting Current Limit
1 Determine the maximum safe current for the device to be powered
2 Temporily Short the
"+"
and
"
-
"
terminals of the power supply togegher with a test lead.
3 Rotated the COARSE VOLTAGE control away from zero sufficiently for the CC indicator to light.
4 Readr the current value on the Ammeten, Adjust the CURRENT control for the desired current limit.
5 The current limit (overload protection) now has been preset. Do not change the CURRENT control setting
after this step.
6 Remove the short lead between the
"+"
and
