TRANSFORMERS
In selecting isolation transformers to be used with the X3, X6
ACE, there is a limitation on the maximum amount of leakage
inductance. If this limit is exceeded, the transmitter rise and fall
times may increase, possibly causing the bus amplitude to fall
below the minimum level required by MIL-STD-1553. In addition,
an excessive leakage imbalance may result in a transformer
dynamic offset that exceeds 1553 specifications.
The maximum allowable leakage inductance is 6.0 H, and
is measured as follows:
The side of the transformer that connects to the ACE is defined
as the “primary” winding. If one side of the primary is shorted to
the primary center-tap, the inductance should be measured
across the “secondary” (stub side) winding. This inductance
must be less than 6.0 H. Similarly, if the other side of the pri-
mary is shorted to the primary center-tap, the inductance mea-
sured across the “secondary” (stub side) winding must also be
less than 6.0 H.
The difference between these two measurements is the
“differential” leakage inductance. This value must be less than
1.0 H.
Beta Transformer Technology Corporation (BTTC), a subsidiary
of DDC, manufactures transformers in a variety of mechanical
configurations with the required turns ratios of 1:2.5 direct cou-
pled, and 1:1.79 transformer coupled. Table 32 provides a listing
of many of these transformers.For further information, contact
BTTC at 631-244-7393 or at www.bttc-beta.com.
Notes:
1. All Transformers in the table above can be used with BU-6XXXXX3/6 (1553B transceivers).
2. Transformers identified with "#" in the table above are not recommended for use with the BU-6XXXXX4 (McAir-Compatable transceivers)
