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
± (10% of AC input + 115 Vac), 50 Hz to 60 Hz
± (10% of AC input + 230 Vac) (max: 250 Vac),
50 Hz to 60 Hz
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.
