The PCM-7700 is a high-power current amplifier with an output that can be set from 5 A to 200 A. It is intended to drive laser diodes, bars, and arrays but can be used for any application that requires high current arbitrary waveforms. The PCM-7700-48 has an internal high-current power supply, whereas the PCM-7700-EX is powered from an external supply. Both models can support load voltage of 0 V to 25 V. In digital control mode, the pulse width can be set from 500 μs to 50 ms with a pulse repetition rate of single-shot to 1 kHz. In analog control mode, it is not limited by width and can amplify arbitrary waveforms.
Included with the unit is an evaluation board with all the necessary controls for the user to begin testing immediately. The output current can be set with the potentiometer on the evaluation board or with an analog voltage. Both analog and digital control modes are supported.
