This is a potentially dangerous condition for both the AE Techron am- plifier and for any user who might come in contact with the amplifier output terminals.

Figure 6.5 – Input to Output Comparison, When operating in Controlled-Current (CC) mode, Controlled-Voltage Operation a compensation circuit is required to ensure ac- curate output current. Since the load is a critical circuit component in CC mode, the inductive and resistive values of the load will determine the required compensation values.
