Informazioni:
                                    The DC Load is a two terminal device that can be connected
to DC sources. Here, a DC source is a voltage that is always
positive on the DC Load's + terminal referenced to the -
terminal.
DC Electronic Loads are used for design, manufacturing and
evaluation of DC power supplies, batteries, and power
components. Other applications include fuel-cell and
photovoltaic cell test. The DC Load can operate under the
following modes:
• Draw a constant voltage from a DC source.
• Draw a constant current from a DC source.
• Draw a constant power from a DC source.
• Present a constant resistance to the DC source (this
behavior simulates a perfect resistor
whose resistance doesn't change as a function of current or
voltage).
The DC Load can present dynamically changing loads to the DC
source with millisecond switching times. The DC Load can be
remotely programmed via a serial interface (RS-232 or USB).
Versatile triggering options allow the dynamic load behavior
to be synchronized with other events.
A battery test mode is provided that will measure the
ampere*hour (A*hr) characteristic of a battery. Shorts can
be simulated by either the front panel or custom
programming. The DC source or other components can be
protected from excessive voltage, current, or power, which
will cause the DC Load to shut down if excessive levels or
reverse polarity are detected.
Dynamic profiles and last instrument states can be stored in
non-volatile memory.
The DC Load is a versatile instrument for static and dynamic
testing of power supplies, batteries, DC to DC converters,
and battery chargers.
