5.8 Make Series (Cascade)/Parallel Setting
The DS3640/DS6024/DS8018/DS10014 uses the series/parallel mode (4 sets in
maximum) that can apparently improve the power supplying capability. Under
the 4-set parallel mode of DS3640 units, the combines unit can offer 36V/160A
power output. And under the 4-set cascading mode of DS10014 units, the
combined unit can offer 400V/14.4A output. Note that you cannot perform both
parallel and series mode at the same time. Series connection will be off once
Series (Cascade)/Paralled connection function is turned on.
5.8.1 Parallel Connection Setting
While connecting four sets of DS3640/DS6024/DS8018/DS10014 in parallel,
the wiring is shown in the following figure:
After wiring is complete, select one DS3640/DS6024/DS8018/DS10014 as the
Master and the other three are Slave A, B and C. After the DS3640/DS6024/
DS8018/DS10014 is set to the Master, it will start searching for all Slaves that
are connected to the Master. Therefore, in order to reach the control status, user
Page 46
37
must set up the Slaves before the Master is set.
To set a DS3640/DS6024/DS8018/DS10014 to the slave mode, press
,
, and
in the main page to enter the series/parallel setting option.
And then select the parallel mode by turning the knob (SCPI command is
“ PS:MODE PARALLEL”) and then press to confirm. It will continue
to the next line for the MASTER/SLAVE selection. Turning the knob to select
SLAVE A (SCPI command is “ PS:TYPE SLAVEA”) for the
DS3640/DS6024/DS8018/DS10014 and press to confirm the setting.
Using the same procedure to set up SLAVE B and C for another two (2)

Once the Master and Slave settings are done, users can then operate the Master
only to set up the output voltage and current.
To release from this operation mode (parallel operation mode in this example),
press (LCL) to access to the series/parallel setting page and turning the
knob to select OFF for series/parallel selection to leave the series or parallel
operation mode and back to the local operation mode that the
DS3640/DS6024/DS8018/DS10014 can be controlled by press the keys again.
It shall not change the operation mode while DS3640/DS6024/DS8018/DS10014
is in output state or it will cause the Master’s communication failure and
display error message.

5.9 External Tuning Setting
DS3640/DS6024/DS8018/DS10014 provides the capability to control the
output voltages by an external voltage/resistance. The range of the external
voltage is in 0 ~ 10 Vdc or 0 ~ 5 Vdc and the range of the external variable
resistance is between 0 ~ 5 Kohm to control the output voltage (0 ~ 36V for
DS3640 and 0 ~ 60V for DS6024 and 0 ~ 80V for DS8018 and 0 ~ 100V for
DS10014) and the output current (0 ~ 40A for DS3640 and 0 ~ 24A for
DS6024 and 0 ~ 18A for DS8018 and 0 ~ 14.4A for DS10014). The wirings of
the external control is shown in the following figure.
Page 52
43
The external voltage control or external resistance control can be set in the
system setting page. Since the external control circuit uses a 12bit D/A
converter for 0 ~ 36V for DS3640 (or 0 ~ 60V for DS6024 or 0 ~ 80V for
DS8018 or 0 ~ 100V for DS10014) output voltage and 0 ~ 40A for DS3640 (or
0 ~ 24A for DS6024 or 0 ~ 18A for DS8018 or 0 ~ 14.4A for DS10014) output
current, therefore, the resolution of voltage and current will be different in
response. The screen thus will show as the following picture (accuracy is
10mV):

5.11 Programmable Capability (SCPI Command Only)
DS3640/DS6024/DS8018/DS10014 provides the capability for users to
program it. There are memory spaces to store 10 programs that can have 150
steps in total for setting purpose. Each program does not restrict the step
quantity, however, the sum of 10 programs are restricted to 150 steps. For each
program users can set up how many times to repeat the program. For each step
users may be able to set up the output voltage, current, and period of time (50
