Characteristics
The COB-740 is a high-power LED light source with peak wavelengths ranging from UV to NIR, designed for applications such as fluorescence, spectroscopy, and general fiber illumination. It features high coupling efficiency to optical fibers via a selectable SMA/FC connector and can operate in continuous (CW) or pulsed modes. An AC/DC adapter is included, supporting input from 100-240V, 50-60Hz.

Electrical Characteristics
Power input requires 10-18 V with a maximum current of 1 A. The input signal for pulsed mode is 0-5 V with a typical current of 5 mA. Connectors include a DC female 2.1mm and SMA female.

Optical Characteristics
The output connector is SMA 905/FC with a peak wavelength of 740 nm and a spectral range FWHM of 18 nm. The typical optical power output is 7.3 mW.

Other Characteristics
Operating temperature ranges from 0 to 50 ºC with humidity below 80% HR. The equipment surface temperature is 40 ºC with a stabilization time of 25 minutes. The device dimensions are 10.5 x 11.5 x 8 cm, weighing 500 g.

Operation Modes
The device includes a MODE switch for selecting between ON, OFF, and PULSED modes. In ON mode, intensity is adjustable between 20% and 100%. In PULSED mode, intensity is controlled via a PWM signal, adjustable between 0% and 100% by changing the duty cycle. The PWM signal should be between 0 and 5 V, with a recommended frequency of 500 Hz, though up to 100 kHz is possible.

Safety Notes
Users are advised not to remove or modify safety devices, as this voids the warranty and creates unsafe conditions. The device contains dangerous currents and no user-serviceable parts. Only qualified personnel should service the unit. Inspect the unit and power supply before first use, and do not use if damaged. Ensure proper ventilation during operation and avoid direct eye exposure to optical radiation.
