and load, the Compensation Network 1 switch can be
turned off and the Compensation Network 2 switch
can be used to enable a network that provides 100k
ohm resistance and 10 nF capacitance and should be
used with loads that are 500
μ
H to 1.5 mH.
NOTE:
It is recommended to only use one of the
compensation networks at a time. Having SW#5
and SW#6 both on (UP) will likely provide improper
compensation for the load, and may result in ampli
-
fier instability.
For more information on Controlled-Current opera
-
tion, including instructions for selecting the best
compensation setting for your application, see the
topic “Controlled Current Operation” in the Applica
-
tions section of this manual. If neither of the avail-
able RC networks is suitable for your application,
please contact
AE Techron Technical Support.
SW#6: Compensation Network 1
When the 8302 amplifier is used in Controlled-
Current mode, the current control loop is tuned
with an RC network. The Compensation Network
1 switch enables the factory default RC network.
This provides 100k ohm resistance and 2.2 nF
capacitance and should be used with loads that
are 50
μ
H to 500
μ
H
. If this default network is not
adequate for your application and load, the Com
-
pensation Network 1 switch can be turned off and
the Compensation Network 2 switch can be used
to
enable a network that provides 100k ohm resis
-
tance and 10 nF capacitance and should be used
with loads that are 500
μ
H to 1.5 mH.
NOTE:
It is recommended to only use one of the
compensation networks at a time. Having SW#5
and SW#6 both on (UP) will likely provide improper
compensation for the load, and may result in ampli
-
fier instability.
For more information on Controlled-Current opera
-
tion, including instructions for selecting the best
compensation option for your application, see the
topic “Controlled Current Operation” in the Applica
-
tions section of this manual. If neither of the avail-
able RC networks is suitable for your application,
please contact
AE Techron Technical Support.
SW#7: Control Configuration
When this switch is in the UP position (default), the
amplifier will function as a stand-alone amplifier or as
a Master amplifier in a multi-amp system. When this
switch is in the DOWN position, the amplifier will func
-
tion as a Follower amplifier in a multi-amp system.
For more information on multi-amplifier system
configuration and operation, see the
Applications
section.
SW#8: Coupling
When the Coupling DIP switch is in the UP posi
-
tion (default), the amplifier can receive and amplify
both DC and AC signal. When this switch is in the
DOWN position, a 30-Hz high-pass filter on the
inputs prevents the transmission of DC signal.
SW#9 – SW#16: Gain
The amplifier gain can be adjusted from 0.16 to 40
in increments of 0.16 using switches 9 through 16.
All switches are additive and provide the following
values toward the total Gain amount.
SW#9 = 20.00
SW#13 = 1.25
SW#10 = 10.00
SW#14 = 0.63
SW#11 = 5.00
SW#15 = 0.31
SW#12 = 2.50
SW#16 = 0.16
Refer to the chart in
Appendix A
to quickly deter
-
mine the switch settings for your desired amplifier
gain.
SW#17: Electronic Gain Matching
The Electronic Gain Matching function serves to
minimize circulating currents when multiple ampli
-
fiers are used in a parallel configuration. When
enabled, the Electronic Gain Matching function
progressively increases impedance from the volt
-
age gain as current increases, up to a mamimum
0.20-ohm increase. This allows the amplifiers to
operate in parallel without the use of separate
ballast resistors. For more information on multi-
amplifier system configuration and operation, see
the
Applications
section.
When the Electronic Gain Matching DIP switch is
in the DOWN position (default), the function is dis
-
abled. When this switch is in the UP position, Gain
Matching is enabled.
