CW Laser Diode Driver LDD480-12A-CW
The laser diode driver (LDD) is designed to feed laser diodes with desired stable current and control the light emission output in CW (continuous wave) or pulsed mode through proportional variation of the output current and voltage at the IPROG control input.
Please refer to the specification below or contact us for more details.

Signal Inputs / Outputs
- GNDI – Ground
- ERROR2 – Over-current, over-voltage indicator. Open collector digital output. Connect to GND = Error
- IMON – Output current monitor. Analog output. 0…10 V = 0…12 A out
- VMON – Output voltage monitor. Analog output. 0…10 V = 0…50 V out
- IPROG – Output current set point. Analog input. 0…10 V = 0…12 A out
- READY – Signal of readiness of LDD. Open collector digital output. Connect to GND = LDD is ready
- ENABLE – Enable digital input. High (+2…+15 V) = Run; Low (< 0.8 V) = Off
- ERROR1 – Over-heating indicator. Open collector digital output. Connect to GND = Error
- INTLOCK – Interlock digital input. Open = off; connect to GNDI = Run
- GNDPI, +15VPI, -15VPI – Auxiliary voltage outputs +15 V, -15 V (current ≤ 100 mA)
