OR
The DC power supply series are a bench top single output variable DC power supply. Stable regulated DC power supplies
allowing continuous adjustment of both the output voltage and output current levels. They have been designed according to
IEC1010–1 concerning safety requirements and comply with.
There are three display types for the power supply series monitoring output voltage and current. They are LCD, LED and two
pointer meters. One of them is equipped to the DC power supply. There are different numbers of output voltage and output
current ranges for the DC power supply series, too. These difference models of the DC power supply are available for choice
of user.

WARNING
To avoid user for injury and the instrument for damage, the voltage value of AC power
must be examined with same the power requirements of instrument before connect power
cord to live power source.
WARNING
To avoid electrical shock, disconnect power cord from live power source and remove the
test leads and any input signals before replacing the power fuses. Replace it only with the
same type of fuses.

Operation
Introduction
WARNING
To avoid electric shock or personal injury, read “Safety Precautions” and “Safety
Information” before Operation.
Before making any operation always examine the DC power supply and accessories used with it for damage, contamination
(excessive dirt, grease, etc.) and defects. Examine the test leads for cracked or frayed insulation and make sure the lead plugs
fit snugly into the output jacks. If any abnormal exist do not attempt to make any operation.
Line Power Supply Setting (Figure 2-1)
(Only for the instrument with POWER SELECT SWITCH )
Two kinds of AC line, 220VAC 50Hz/60Hz or 110VAC 50Hz/60Hz, can be supplied to the instrument. Set it with a screwdriver to
adapt your AC line.
Check to be sure that power select switch on back panel is switch to correct line voltage.
Check to be sure that fuse is correct rating current.

1.
Turn the voltage regulator clockwise to maximum position and the current regulator anti – clockwise to minimum
position.
2.
Press the power ON/ OFF switch to ON.
3.
Connect the positive output terminal and negative output terminal with a load or similar component.
4.
Turn the current regulator clockwise to that you are desirous of output current value.
5.
The voltage regulator controls the output voltage indicator. The current regulator controls the output current indicator.
Indicator show that output voltage and current of the output terminals.
RESTRICTED CURRENT PROTECTION MODE
1.
Press the power ON/ OFF switch to ON.
2.
Turn the current regulator anti-clockwise to minimum position then clockwise a little.
3.
Turn the voltage regulator clockwise to that you are desirous of output voltage level position (approx.1.5V).
4.
Link the positive and negative output terminals with a wire.
5.
Turn the current regulator clockwise to get the current level at which the restricted current protection will be active as
you desire.

Users Manual
6.
Remove the wire linked to the positive and negative output terminals. Connect the positive output terminal and negative
output terminal with a load or similar component.
7.
When the output current achieves the setting value of restricted current protection, and the restricted current protection
is active.
NOTE: After setting of the restricted current protection, if the current regulator is turned again, the restricted current protection
range will be changed.
C.C. AND C.V. INDICATOR (Only for the instrument with C.C. and C.V. INDICATOR )
The C.C. indicator is controlled by the constant current mode. Otherwise C.V. indicator is controlled by the constant voltage
mode.
CAUTION
The DC power supply series has perfect restricted current protection, Even so, when the output terminal is short - circuit, the DC
power supply should be turned off and the short - circuit should be removed before continuing operation because the power
transistors in the instrument will bear heavy.
The AC power must be switched off before servicing and servicing should be referred to a qualified person.
CAUTION
Using this appliance in an environment with a strong radiated radio - frequency electromagnetic field (approximately 3V/m) may
influence its measuring accuracy.
