2.5 Location
The operating temperature of the MDL4U Series DC Electronic Load is 0 to 40 ℃. A fan cools the electronic load by
drawing air through both the top and front, and then exhausting it out the back. Therefore, the electronic load must be
installed in a location that allows sufficient space on the front and back of the unit for adequate air circulation.
Minimum clearances for bench operation are 2 inches from the top and 3 inches from the front and back. If there are
radiator fans in your cabinet, please avoid installing the load near the fan, since it may limit air circulation of the load.
If you are installing equipment on top of your electronic load in the cabinet, use a filler panel above the unit to ensure
adequate air circulation.
Caution:
Do not block the fan exhaust at the rear of the load. When the load is used on a
bench, make sure there is enough space on the front and rear of the equipment for air
circulation.
2.6 Input Voltage Selection
The electronic load can work under 110/220V±10% AC input, identified by an input line voltage switch on the rear (refer
to Figure 2.8 ). If the indicated line voltage does not match your region, please use the switch in the back of the unit to
choose your input line voltage, install appropriate fuse (refer to Table 2.2 below), and then insert power cord.
Caution:
Check to make sure correct fuse is installed when line voltage is switched.
