Cosimat N+ AVR From Avk Germany

• Integrated measuring transformers for three-phase measurement of the alternator voltage up to 500 V AC (external conductor voltage).

• Stable reactive power thanks to current-voltage vector measuring system (droop). A load-relieved current transformer

is required in alternator phase ”V”.

• Internal and external alternator voltage set-point adjustment.

• PID control amplifier with large adjustment range.

• Disproportionate drop in desired value when alternator operates at underfrequency.

• Permanent monitoring of the actuator and time limit on

the max. possible excitation current. 

• Internal protection devices trip whenever a fault occurs, thus separating the excitation field from its energy source.

• Compact construction with interchangeable power stage.

• Fully potted in to protect it from environmental effects.

• Long life thanks to high-quality components. With the use of additional modules it is possible to intervene

in set-point and actual value formation via the ”COSIMAT N+”

signal inputs:

There are a large number of additional modules available for a wide variety of control applications e.g.

• cos phi regulation of a synchronous alternator or motor

or

• Limitation of start-up current when connecting up a large asynchronous motor to the alternator

or

• Cable compensation via load current detection or measured value of the external alternator voltage. Its additional modules make the "COSIMAT N+" suitable for

various applications on test rigs, in power-train technology etc.
