TEC Laser Drivers

TEC Laser Drivers

  • Compact design
  • Bidirectional TEC Control
  • Switching technology: high efficient driver
  • NTC resistor as a temperature sensor
  • PID for precise temperature control (0,01º C)
  • Security stop when the sensor is open/shorted
  • External shutdown control 2,5 V
  • Reference voltage output
  • Current soft-start for controlled start-up
  • Visible running by LED
