CW Laser Diode Driver LDD350-100A-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 QCW (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.
-
Specification
- Maximum output current CW – 100 A
- Maximum output current pulsed – 100 A
- Maximum output voltage – 3.5 V
- Supply voltage – 8…15 V
- Rise/Fall time – < 100 us (at Rload ≤ 10 mOhm)
- Current regulation – < 1 % of maximum output current
- Output current monitor – 100 mV/A
- Output voltage monitor – 2.5 V/V
-
Signal Inputs / Outputs
- GNDI – Ground
- IMON – Output current monitor. Analog output. 0…10 V = 0…100 A out
- VMON – Output voltage monitor. Analog output. 0…10 V = 0…4 V out
- IPROG – Output current set point. Analog input. 0…10 V = 0…100 A out
- PGOOD – Power good signal of the output current. Open collector digital output. Connect to GND = Power good
- ENABLE – Enable digital input. High (+2…+15 V) = Run; Low (< 0.8 V) = Off
- ERROR – Over-current, over-voltage, 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)
General Specifications
- Overall dimensions – 100 * 140 * 22 mm
- Ambient temperature 0…45 0C
- Air cooling
