STEP 2: Determine Required Compensation.
When operating an amplifier in Controlled-
Current mode, the load becomes an integral part
of the system. In order to determine the required
compensation for your load, consulting the follow
-
ing table to determine the approximate compen
-
sation capacitance (CC) required based on the
inductance of your load. Note that these calcula-
tions are based on empirical measurements and
are approximate.
If your load inductance is between 75
μ
H and 1
mH, and your load resistance is less than 5 ohms,
then you can likely use Compensation Network
1 for your application. If your load inductance is
between 1 mH and 5 mH, and your load resis
-
tance is less than 5 ohms, then you can likely use
Compensation Network 2 for your application.
(See
Figure 6.4
). These compensation networks
NOTE: Load Resistance (R) is assumed to be
<5 ohms.
STEP 3: Enable Compensation Network
are enabled when Compensation Network 1 DIP
switch (SW#6) or Compensatlon Network 2 DIP
switch (SW#5) on the Master amplifier module is
set to the ON (UP) position.
If your load inductance falls outside of these
ranges, or if your load resistance is greater than
5 ohms, please contact
AE Techron Technical
Support
for assistance.
STEP 4: Verifying Operation
Remember the load you are connecting is a
part of the system and the amplifier should not
be turned on without the load being connected.
After selecting and enabling your choice of Com
-
pensation Network, check to ensure that the
Operation Mode DIP switch is set to CC (DOWN),
then power up the amplifier without signal input.
