Load box LP-3
Product overview:
This load box is designed and manufactured according to
IEC60884,IEC61058,IEC606691 standards and etc. It is used for the
on-off ability test and the normal operation lifespan test of the
Switches for household and similar fixed-electrical installations.
Besides, it is also applied in the test of breaking volume of plug
and socket, and mechanical action of normal operation lifespan.
This device is with blue framework and gray cover. The top of this
apparatus is the operation control panel on which there are
switches for controlling power supply, for the electric capacity
conversion and for the load type conversion. There are also the
displaying meters of connecting current and voltage as well as
power, the buttons of start and stop, alarm, the status indicator
light and so on. Below are the according knobs for output voltage
adjustment, for current adjustment and for inductance adjustment.
There are three load lines. Each of them has the function of
resistive, inductive and capacitive Load test. The kind of load
test can be chosen by the transferring switch. The load box inside
is cooled by the strong wind convection. There are terminals below
the load box through which the load box can be connected with the
switch and plug-socket endurance tester using the wire. During the
process of test, the equipment outputs the current and voltage as
well as power.
