Three Stations Load Box HC9915B
Standard for Three Stations Load Box:
IEC 60669-1, IEC 60884-1 2013 clause 20 and 21, IEC 60950-1, IEC
60598-1, IEC61058-1 and so on
Application of Three Stations Load Box:
This device is used for household and similar purpose fixed
electrical appliance switch, plug and socket, coupler for on-off
ability, breaking capacity and normal operation life test.
Test Sample of Three Stations Load Box:
Household or similar purpose switches, plugs, sockets
Feature of Three Stations Load Box:
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 stations, each station 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.
