Technical FAQ
Configuration questions for Laser Power Supply
How are readings taken from the Laser Power Supply?
Maximum output current (constant current source): 3A / 10A · Maximum output voltage: 5V (with function of self-adapting diode laser voltage) / 12V (with function of self-adapting diode laser voltage). Confirm how readings leave the instrument before designing it into an automated measurement. A front-panel display is not a data interface, and logging rates differ from display update rates.
