2105 OPERATOR'S MANUAL – SECTION 5
In Controlled-Current Mode, the load is part of the amplifier circuit, and the relationship of the
load to the amplifier is critical. For proper and safe operation in Controlled-Current mode, you
must obverve the following guidelines:
1. Properly attach a load before operating the amplifier. Use only the Output and Sampled
Common terminals. DO NOT use the Common terminal.
2. DO NOT use a blocking capacitor. The load must have a DC path.
3. Never leave the load open. If you feel the load must be fused, which could lead to a poten-
tial open circuit, please contact AE Techron Application Engineering department.
4. Check to make sure the load has some inductive component.
5. Provide appropriate Compensation for the load.
6. Turn of the amplifier immediately if oscillation occurs.
Failure to follow these guidelines may result in damage to the amplifier
or load.
5.2.3
Controlled Voltage or Controlled
Current Setting
To allow the 2105 amplifier's output voltage to be
controlled by its input voltage signal (CV mode),
place Jumper J4 in the RIGHT position (right pair
of pins). To allow the 2105 amplifier's output cur-
rent to be controlled by its input voltage signal (CC
mode), place Jumper J4 in the LEFT position (left
pair of pins). See Figure 5.5. For more informa-
tion on Controlled-Current operation, see the "Ap-
plications" section of this manual.
5.2.4
Compensation Setting (applies
to Controlled Current operation
only)
When the 2105 amplifier is used in Controlled Cur-
rent (CC) mode, the current control loop is tuned
with one of two available RC networks: CC1 (R63
and C16) or CC2 (R82 and C25). Place Jumper
J5 in the UP position to select the CC1 network
(factory default). Place Jumper J5 in the DOWN
position to select the CC2 network. See Figure
5.6. For more information on Controlled-Current
operation, see the "Applications" section of this
manual.
