SF6015 Laser Diode Driver; 15A / 10V

Product Overview:

15 Amp, 10 Volt OEM Laser Diode Driver Module Overview

These high performance OEM laser diode drivers are used extensively in demanding industrial laser applications. The SF6xxx series of CW drivers are used for laser marking, welding, soldering, and cutting applications. They are also used in medical equipment and laser measurement equipment such as spectrometers, LIDAR and range finders. In addition to high reliability and small form factor components, the SF6xxx series CW drivers offer multiple levels of protection for high power single and multi-emitter lasers. A soft-start ramp to the drive current set point reduces thermal shock to the laser. Other key protection features include a user adjustable driver current limit, over-current protection, over-temperature protection and protection against reverse current transients.

Sourcing Current to your Laser and the Crowbar Clamp Protection

The modules are initially enabled by applying an active high 3.3V ~ 5V DC compatible logic input signal. The driver sources current and begins to operate when the 5V input enable pin is high. To ensure that the current enable is applied without overshoot, a slow start sequence initiates when the enable pin is set high. The enable pin can also be used in the quasi-CW mode. The output current is set by applying an analog signal to the current set pin on the control connector. The current set pin can be used for analog modulation by applying sign wave, square wave or ramp signal. The output may be pulsed by applying a TTL square signal to enable pin. The minimum pulse duration 500 microseconds.

These high power drivers offer a highly reliable crowbar clamp to short the current and disable power to your laser diode. There is a pin on the control connector which shows the crowbar protection circuit status. The crowbar will short the output while the module is in an over-current shutdown or an over-temperature shutdown mode.

Driver Safety Interlock, Current Monitoring and Voltage Monitoring

These SF6 units have an interlock pin which must be connected to the ground order for output current to be enabled. The safety interlock is used to shut-down the module with a logic high signal triggered by and external interlock trigger such as a door to the lab or an external over-temperature circuit. These modules also have an on-board temperature sensor which will shut-down the output when the temperature exceeds a pre-set temperature. The output voltage of the driver can be monitored by a linear scaled voltage monitor output, 0~1V. The voltage is measured between LD+ terminal and GND. The current can be monitored by a linear voltage output, 0~1V = 0~3A also with +/-2%.

Recommended Power Supply

The OEM laser module requires an external power supply, such as the Mean Well RS-150-12. This power supply is available as an add-on to the order, and can be found in the Cart.
