The AAS12A12V2 is an electronic power supply brick designed for driving diode lasers with up to 12A low noise current. The output current can be set by an analog voltage of 0V to 2.5V, an external potentiometer, or the built-in internal potentiometer, to between 0 and 12A.

A pulsed output current can be generated by driving the PCN port with a digital signal, under which, the peak output current is set by the LISH port while the valley output current is set by the LISL port. The modulation frequency can go up to 5kHz, resulting to an approximately 56S rise/fall time at the output current.
