Powerul DSP ensures ast and precise
voltage control
UNITROL 1000-7 is the latest and most compact member in the
UNITROL 1000 Family o AutomaticVoltage Regulators. Its smart
mechanical design together with modern digital signal
processingtechnology guarantees excellent perormance also under
harsh environmental conditions. Theunit complies with relevant EN,
ANSI, UL and CSA norms.
Applications of UNITROL 1000-7
Superior reliability
UNITROL 1000-7 consists o a single printed circuit board
equipped with all elements o the control as well as the
power electronics. This board is attached to an eective
heat sink which cools the power components. The surace
o the board is casted in polyurethane, which makes the
mechanical structure extremely robust and resistant to
mechanical stress and dusty environments. This design
guarantees excellent perormance and reliability at reason-
able prices.
Adaptation to customer needs
The powerul signal processor has signicant spare
capacity to handle additional unctionality required by
a machine manuacturer. Even small hardware changes
can be considered.

CMT 1000 is a user-riendly Commissioning and Maintenance Tool or
the UNITROL 1000 Family.

Simple tuningAll the parameter settings or the
UNITROL 1000 Family can be perormed
usingCMT1000,CommissioningandMain -
tenanceTool,forMicrosoft Windows.
It is easy to see how the changing o a
parameter aects the overall behavior o the
regulator by reerring to the power chart and
oscilloscope unction. This means that the
optimum settings are ound within a short
time. A program or tuning aid is provided.
Typically, the UNITROL 1000-7 is presetduring machine testing
and the site personnel
only need to veriy the correct operation.
