To Connect to Power Supply
Two kinds of AC power inputs are supported by DL3000 series electronic load.
When the DL3000 series is connected to different power sources, the AC
selector setting on its rear panel is different, as shown in Table 1.
Table 1 AC Input Power Specification and AC Selector Setting
AC Input Power
AC Selector
± (10% of AC input + 115 Vac), 50 Hz to 60 Hz
115
± (10% of AC input + 230 Vac) (max: 250 Vac),
50 Hz to 60 Hz
230
Please strictly follow the steps below to connect the DL3000 electronic load to
the power supply.
1．Check the input power
Ensure that the AC power to be connected to the load conforms to the AC
input power requirement specified in Table 1.
2．Check the AC selector
Ensure that the AC selector setting (115 or 230) on the rear panel of the
load matches the actual AC input power (For the match relationship, refer
to Table 1).
3．Check the fuse
When leaving the factory, the load has installed a fuse that conforms to
the destination country standard. Please refer to the "fuse rating" on the
rear panel of the load to ensure that the fuse matches the actual AC input
power.
4．Connect the AC power
Plug the specified power cord available in the accessories into the AC
power supply connector of the instrument, and then connect the
instrument to the properly grounded AC power.
WARNING
To avoid electric shock, ensure that the instrument is correctly
grounded.

Remote Control
DL3000 electronic load can be connected to the PC via the USB, LAN, GPIB, or
RS232 interface to build communication and realize remote control. The remote
control can be realized by using SCPI (Standard Commands for Programmable
Instruments) commands. DL3000 electronic load supports two ways of remote
control: user-defined programming and PC software (e.g. RIGOL Ultra Sigma).
When the instrument is in remote control, the icon is displayed on the
interface. The keypads on the front panel are locked. At this time, you can press
Local to exit the remote mode.
