About the IS200VATFG1AAA

The board achieves attenuation through two sets of identical strings of series-connected precision resistors with input connections (stab-on connectors) at places along the string to allow for the accommodation of a range of voltages. The control power for this model is derived from the distributed high-frequency AC power source. The IS200VATFG1AAA board has dielectric isolation; this isolation is between the VATF high voltage ground plane and the control power, the input for this isolation is 8000 V rms. The IS200VATFG1AAA is built with:

eight stab-on connectors
two fiber-optic transmitter connectors
five TP test points
two plug connectors
one LED indicator (PSOK.)
single transformer
one heat sink component
several integrated circuits
- electrolytic
- ceramic
- and polyvinyl capacitors
a single resistor network array

Voltage Suppression information

When the IS200VATFG1AAA model is being operated it will accept three-phase AC input voltages. Two of the three phases, specifically phases two and three of the input will be applied to two identical precisions resistors to reduce high voltages to signal electronic levels. The electronic levels are related to phase one. Phase one of the VATF board directly connects to the high-voltage ground plane.

One of the alternative features of the VATF board is that it can measure the two DC rail voltages relative to the DC neutral or midpoint. This IS200VATFG1AAA product is something of a well diagnostically-supported GE Mark Series product offering, as its offered with a series of relevant test points. Some of the specific test points afforded to this IS200VATFG1AAA product's normal Mark VI Series assembly include its

V1 TP1 High voltage common testpoint
HV_P15 TP2 Positive 15 V dc testpoint
HV_N15 TP3 Negative 15 V dc testpoint
HV_P5 TP4 :Positive 5 V dc testpoint
HV_ACOM TP4 High voltage analog common testpoint

Frequently Asked Questions about IS200VATFG1AAA

There are two groups of VATF boards; are there any major differences between the two groups?

Yes. The differences are between the frequency biases. The G1 board, which this model is, does not have a frequency bias; the frequency offset for the G1 group is 1000 kHz. The G2 board is equipped with an additional resistor which creates a frequency bias of 2%; the frequency offset for boards in the G2 group is 1020 kHz.

What are the test points again on the VATF board?

There are five test points available on the VATF board. There are different nomenclatures and descriptions for each one. The TP1 nomenclature is V1 with a description of high voltage common. The TP2 nomenclature is HV_P15 with a description of positive 15 VDC. The TP3 nomenclature is HV_N15 with a description of negative 15 VDC. The TP4 nomenclature is HV_P5 with a description of positive 5 VDC. The final test point TP5 has a nomenclature of HV_ACOM with a description of high voltage analog common.

Reviews For IS200VATFG1AAA

Internal Review

(5.0)

The VATF board has two available VCO feedbacks, these feedbacks are synchronous, and the VCOs are configured for bipolar inputs used to create feedback pulse trains. The VCO is based such that the 0 V inputs will equal 1 MHz for G1 boards. This IS200VATFG1AAA product's three seemingly-identical A-rated significant product revisions truly exist as two functional product revisions and a singular artwork configuration revision, which mean that only this IS200VATFG1AAA device's first two revisions are backwards-compatible. Repair or replace. - AX Control Lead Technician
