The
DVS3 mk2 is the new smaller,
lighter, higher power version of
the DVS3, offering more
than twice the output power of
the original DVS3. The
exceptionally easy to understand
user interface of the DVS3 is
retained, allowing simple
testing of complex voltage and
loss of mains protection
systems.

Equally
at home in a commissioning,
maintenance, or laboratory
environment, the DVS3 mk2 is a
truly flexible system. The DVS3
MK2 has been designed using the
latest digital technology to
generate a highly stable and
accurate output with very low
distortion. Each phase output is
individually adjustable for
voltage and phase angle. In
addition, full control of
frequency is available. Step
changes of any quantity may be
generated with automatic timing
of the response of the relay
under test.

The
unit is controlled by a simple
user interface with context
sensitive menus. Values may be
either typed in at the keypad or
smoothly varied using a digital
potentiometer.

The
display on the DVS3 is back-lit
and exceptionally clear. Menu
options on the left are selected
by dedicated buttons on the
panel next to the display,
allowing immediate access to
adjust voltage, phase and
frequency. Phase to phase and
phase to neutral voltages are
both shown on the display, along
with frequency and phase
information. A graphical vector
diagram is shown, as is the
state of the two contact inputs.
