The UNITROL 1000-15 is an Automatic Voltage Regulator o the latest design or synchronousgenerators and synchronous motors. The implementation o the most advanced microprocessortechnology together with IGBT semiconductors enables it to be used in a wide range o applications.The maximum output current is 15 A and the power input can be rom an AC or DC source.

UNITROL 1000-15 Covers a wide application range

Shunt excitation with optional short circuit support

Replacement of voltage regulators for generators with direct-

current exciter machines with UNITROL 1000-40. A suitable

solution for modernization of older mechanical or analog

voltage regulators.

The UNITROL 1000-PM40 is a microprocessor controlled chopper

type power stage with IGBT semiconductors. It is connected to

a UNITROL 1000-15 AVR by a CAN bus. This combination called

UNITROL 1000-40 covers a eld current range up to 40 A.

LEDs (Light Emitting Diodes) on the ront plate o the UNITROL

1000-PM40 provide the most important status inormation

Additional settings or commissioning are not required since the

power stage is automatically congured by the UNITROL 1000-15.

UNITROL 1000-40 is a perect solution or retrot applications

where eld current between 15 A and 40 A is needed.

UNITROL 1000-PM40

The UNITROL 1000-15 has all the elements o

excitation control built inside. A powerul signal

processor running extensive control sotware

guarantees excellent perormance under all

conditions. The chopper type power stage, which

can be supplied rom an AC or DC power source,

enables the use in varied applications. The ront

panel serves or easy monitoring and conguring.

The robust mechanical design guarantees a highreliability. The applications shown here are

typical examples.

All o the parameter settings or the UNITROL 1000

Family can be perormed using CMT 1000 Commissioning and Maintenance Tool or

Microsot Windows.

It is easy to ollow how the changing o a

parameter aects the overall behavior o the

regulator by reerring to the power chart and

the oscilloscope unction. This means that the

Single-channel system

The single-channel solution, with all the necessary components

installed on a mounting plate, is requently used or the excitation

o smaller synchronous machines, e.g. generators that are driven by

hydro turbine or by a diesel engine. This is also a commonly used

solution or motor excitation.

Dual-channel system

A dual-channel system with its 100 % redundancy isused when there are higher requirements in terms o

reliability and security against ailure.
