The description sections and FAQ are machine-assisted and can contain errors; where they disagree with the record, the record is correct, and where description sections disagree with each other, Details wins._ ## Summary - Manufacturer: Newport - Model: LDC-3916371 - Condition: Used and in Excellent Condition - Price: $1,695.00 USD - Availability: In stock, 66 available - Warranty: 1-Year Warranty with 30-Day Return Guarantee - ITAR restricted: No - Shipping weight: 3 lb - Shipping dimensions: 18X9X9 in ## Categories - Test Equipment > Optical Test > Laser Drivers (primary) - Test Equipment > Optical Test > TEC - Military and Embedded Equipment > Embedded & Industrial > Other Modular ## Details Laser max current: 0.5 A & TEC max power: 9 W. Temperature Range: -5 to 50 C. The LDC-3916371 Laser Diode Controller Module is a combination laser current source and temperature controller. This module is targeted for DWDM signal source DFB lasers and has higher temperature resolution for fine tuning the wavelength of the laser. The built-in bi-polar temperature controller can work with thermistor type temperature sensors and most TEC modules to deliver precise laser temperature control. Other features of the TEC control circuit include TEC voltage measurement and control loop gain adjustment from 1 to 127. The laser current source provides high stability output of up to 500 mA with fully redundant current limits and multiple laser protection features such as contact bounce detection, voltage limit adjust, and 4-wire voltage measurement for precise laser voltage measurement. ## Images -
