7212 OPERATOR’S MANUAL – SECTION 6 6.2.3 Controlling Compensation for CC Operation AE Techron 7212 amplifiers can be configured for either Controlled Voltage (CV) or Controlled Cur- rent (CC) mode of operation. When operating the amplifier in Controlled Voltage (CV) mode, com- pensation is not required. However, when operat- ing in Controlled Current (CC) mode, the amplifier load becomes an integral part of the system. In order to ensure system stability and to control Figure 6.9 – Input to Output Comparison, available bandwidth, compensation via an RC Controlled-Current Operation network is required for CC operation.
