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.
STEP 3: Enable Compensation Network
If your load inductance is between 75 μH 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
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.

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.
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.
