Instruction Manual

1. Instalation and handling precautions
When plac ng the Power Supply n serv ce at your workplace, observe the follow ng precaut ons for
best nstrument performance and longest serv ce l fe.
1) Avo d plac ng th s nstrument n an extremely hot or cold place. Spec f cally, don’t leave
th s nstrument n a closed car, exposed to sunl ght n m dsummer, or next to a space
heater.
2) Don’t use th s nstrument mmed ately after br ng ng t n from the cold. Allow t me for t
to warm to room temperature. S m larly don’t move t from a warm place to a very cold
place, as condensat on m ght mpa r ts operat on.
3) Do not expose the nstrument to wet or dust env ronments.
4) Do not place l qu d-f lled conta ners (such as coffee cups) on top of th s nstrument. A sp ll
could ser ously damage the nstrument.
5) Do not use th s nstrument where t s subject to serve v brat on, or strong blows.
6) Do not place heavy objects on the case, or otherw se block the vent lat on holes.
7) Do not use th s Power Supply n strong magnet c f elds, such as near motors.
8) Do not nsert w res, tools, etc, through the vent lat on holes.
9) Do not leave a hot solder ng ron near the nstrument.
10) Do not place th s nstrument face down on the ground, or damage to the knobs may
result.
11) Do not connect other power source to +.- of the output term nal.

28) Power Sw tch
4.1. Constant voltage setting method
1) Turn on power sw tch.

2) Adjust voltage sett ng knob to the des red voltage wh ch can be shown n the LCD d splay.
3) Connect the load, make sure the load current not exceed ng the max mum output current.
4.2. Constant current adjustment method
1) 1.Adjust by turn ng the voltage sett ng knob to des red voltage.
2) Press the CV/CC sett ng button down to l ght up the CC/CV sett ng nd cator.
3) Use a w re to shorten the (+) and (-) term nal at output term nal.
4) Push the UP or DOWN button to obta n the current value.

7. Dual function

W th th s funct on, you can s multaneously ground channel 1 and channel 2 to get +30V and –30V
outputs, proceed as follows :
1. F rst do not turn on power.
2. Short the output (+) term nal of channel 1 and channel 2 w th a short w re.
3. Turn on the power sw tch, push “ser al” button down to l ght up the nd cator, and you
can get negat ve output voltage of 0~30V from channel 1 and pos t ve output voltage of
0~30V from channel 2. as shown n the d agram.
4. In order to l m t the current for +/- supply, you can perform the sett ng of CV/CC
procedures to get the des red current output.
5. Do not forget to remove short w re of output term nals when operat ng n other mode.

1) When the operat on s under PARALLEL cond t on, when act vat ng the SERIAL button, the
operat on w ll be changed from PARALLEL cond t on to SERIAL cond t on.
2) When the operat on s under SERIAL cond t on, when act vat ng the PARALLEL button, the
operat on w ll be changed from SERIAL cond t on to PARALLEL cond t on.
3) When the un t s used n nductance load (l ke DC electr c buzzer), nstall a 4,700uF ~
2,200uF/50V electrode capac tor across the extens on term nal, connect on please refer
to F g 8

4) When the un t s used w th the h gh frequency nstruments (l ke ultrason c solder ng tool),
the electr c power supply should be grounded.
