Overview
The AMPX.CW15A_LV is a high-power laser diode driver optimized for CW mode. The driver has an integrated low-pass filter for decreasing ripples. The circuit of the driver is optimized for high efficiency driving of low voltage laser diodes and modules. AMPX.CW15A_LV is fully digitally controlled via CAN 2.0A, USB or other interfaces. Ideal for air-cooled systems.
