1.Summary
72-8000 is a series of general DC power supplies suitable for laboratory use.
Both CH1 and CH2 may work in CV or CC mode, and these two modes convert
automatically according to the load. CH1 and CH2 have auto tracking function. In this
condition, the output of CH2 tracks the output of CH1. This function is usually used
when adjustable symmetrical and double polarity power is required. Both CH1 and
CH2 display the output voltage or current with a 3-digit-LED meter.
CH3 is a 5V xed output. Its maximum output current is 2A, and it is usually used in
TTL circuits etc.
CH1, CH2 and CH3 all have overload protection.

2.Applications
The left area of panel corresponds to CH1 and the right area of panel corresponds
to CH2. When the left MEASURE is pushed out, the CV lamp switches on, and the left
digital meter displays the output voltage of CH1. When this button is pushed in, the CC
lamp switches on, and the left digital meter displays the output current of CH1. CH2 is
same as CH1.
When the MODE button is pushed out, each CH1 and CH2 works independently.
When this button is pushed in, CH2 tracks to CH1.
The output of CH1 and CH2 are suspended. You can set the negative level of
output by connecting the reference point to the “-”terminal.
Each CH1 and CH2 can output from:
0V to 32V and from 0V to 3A (adjustable)
0V to 64V and from 0A to 3A current (adjustable in series)
0V to 32V and from 0A to 6A (adjustable in parallel)
The “-”terminal of III channel has been connected to the ground.
A protective grounding connection is essential for safe operation. This is helpful to
reduce the ripper and also the 50Hz noise
