About the IS200EACFG3B

Exciter AC Feedback Board IS200EACFG3B is part of the IS200EACF series of models. This model can support up to 1400 VRMS of voltage feedback measurement. The IS200EACFG3B module of the IS200EACF series looks the same as the modules of the IS200EACFG2A on with the four terminals that measure the incoming phase voltages. 

The IS200EACFG3B module is the primary controller that handles the bridge voltages and current feedback. The module also has a terminal block that controls the voltages of the flux/air coils. As this module is the last of the IS200EACF modules it will typically replace the IS200EACFG3A models, this module is better used for higher voltage ratings and will replace the IS200EACFG3A module. This module is only a base-level module with its 200 assembly level. 

The IS200EACFG3B board is one of two that are part of the high voltage interface (HVI). The other board that is part of the HVI is the exciter DC feedback board which controls the DC voltages. The EACF and EDCF boards work with each other to control the two different feedback voltages. 

This module is far more widely available than the IS200EACFG3A model and can replace the previous model. AX Control can help you acquire the IS200EACFG3B model for any of your needs. 

Frequently Asked Questions about IS200EACFG3B

Does the IS200EACFG3B model differ from the IS200EACFG3A model?

Yes, the G3B version requires 1400 VRMS compared to the G3A version which requires 1300 VRMS. 

Are there any special functions for the IS200EACFG3B board?

Yes, this board is a High Voltage model and is only one of two, the second is the EDCF board that controls the DC voltages rather than the AC voltages that the EACF controls. 

How does the IS200EACFG3B connect to the required EBKP backplane model?

The connection is made through three DB9 connectors, the connecting cable can reach up to ninety meters in length. 

As the IS200EACFG3B board is high voltage are there any special features that the high voltage interface allows?

No, the IS200EACFG3B board simply accepts incoming PPT AC voltages as well as air core CT current signals, and will then isolate the voltages and produce low-level signals.
