Connection to Secondary Battery
Since this machine lowers the output voltage rapidly, it has the sinking function that absorbs the current from the
load side.
For this reason, if connected with the secondary battery, constant current discharge occurs due to sinking current
when output is turned OFF.
To prevent discharge from the secondary battery, it should be used connected with a reverse current blocking diode.

*Sink current is the sum of the parallel-connected unit in the case of parallel connection.
• If sensing is done with the secondary battery connected and the reverse current
blocking diode equipped, a potential difference occurs between each output and the
sensing terminal because the secondary battery becomes the source of voltage at
power supply's output OFF. If this potential difference exceeds about 10V, the
protecting circuit works and measurement display of voltage at the load end becomes
incorrect.
• If a reverse current blocking diode is connected, the error of voltage measurement
display may become large because the input impedance bS and -S is very
large.
In this case, the error can be reduced by connecting an electrolytic capacitor (C1 to
2) between each output and the sensing terminal (bOUT and +S, and
between -OUT and -S).
As the additional electrolytic capacitors, use low-impedance ones which is 10 to
100μF and whose voltage is the assumed maximum voltage or more.
