VIS Voltage Integrated Source
ISO 9001:2000
Features:
Broad range of output voltages
Broad range of allowable loads
High accuracy and stability
Low harmonic distortion
Multilevel protection system
Integrated Digital Signal Generator
Generation of harmonics
The VIS Voltage Integrated Source is a
single-phase alternating voltage source, designed
for use in electricity meter testing systems and in
laboratories. The output voltage is isolated and
independent of mains voltage.
The power stage of the source utilizes the
Power Width Modulation (PWM) technology,
which ensures high efficiency and thus contributes
very small heat losses. The stage is driven by an
onboard Digital Signal Generator. The control
signal may be composed of harmonics of
independently defined amplitudes and phases. The
internal feedback loop utilizes the DSP technology.
Advanced algorithms applied ensure high stability
of amplitude and phase angle as well as low
distortions of the output voltage over a full range of
allowable loads of various characters.
A multilevel protection system implemented
protects the source against overload, short circuit,
overheat and makes operation of the device reliable
and safe.
The VIS device is equipped with an isolated
serial interface and can be operated by a PC or
other controlling device (host). A number of
sources can be synchronized and operated together
to form a poly-phase system. The communication
protocol is provided to control output settings as
well as to access all internal registers.
The VIS Voltage Integrated Source is
accommodated in a 19 inch plug-in case.
