The AMPX.PWM15A_HV is a high-power laser diode driver optimized for both CW and low-frequency PWM modes. The driver has an integrated low-pass filter. The circuit of the driver is based on FETs for high efficiency. AMPX.PWM15A_HV is fully digitally controlled via CAN 2.0A or isolated USB interfaces. The driver offers various safety features: interlock signal, allow signal, diode and driver temperature monitoring. Ideal for both air- and water-cooled systems.
