It can work with 20, 40, and 60W CS-mount 808nm, 940nm and 980nm laser diodes as also with other similar diodes. With this driver you can power one diode or several diodes in series as also one diode stack which requires higher working voltages. In recommendation section there is a formula for maximum input voltage. Separate laser diode supply voltage input and logic input voltage allows to minimize the switch-on resistance of a power MOSFET. Inner layer of the heatsink is made of copper and helps in fast heat transmission. The outer body of a heatsink, made of alluminium, is isolated from all signals on the driver, including GND signal. It allows to mount the driver directly to the metal components in case of additional cooling needed. Analog input allows for the modulation of the current flowing through the diode up to 5 kHz. Two potentiometers are used to set the values of maximum diode current and bias current. Attached to the driver is connector and pins which are used to power and control the unit as also the M5 stainless steel screws. We can also supply the proper power supply unit. Please feel free to contact us with any questions.Recommendations and requirements Supply voltage range depends on the quantity of laser diodes used in series. For one laser diode which operating voltage is around 2V, maximum diode input voltage should not exceed 5V. For two diodes which operating voltage is around 4V, maximum diode input is 7V and so on. Therefore the maximum input voltage is given by the formula: VCC DIODE MAX = (Number of diodes in series) X (Each diode operating voltage) + 3V Always power the logic with 12V before powering up the diode line. Because GND of the diode line and GND of the logic input are connected in the driver, always remember to connect GND of the diode line directly to the GND of a PSU. Always use high quality power supply unit with low ripple voltage. Adding large capacitor at the driver input is strongly recommended, but it depends on PSU, wires cross-section and their length. The capacitor used during the tests was 10000uF 25V. You should be very careful not to cause short circuit between the + (VCC) of the power supply and -(GND) of the logic input or monitor input, as a thin GND logic paths can be irreparably damaged. Modulation input can be used as TTL input with its logic levels of 0V and 5V or as an analog input. Analog modulation means that by using 2,5 V on ANG input you get 50% output power, analogically by using 4 V you get 80% output power, etc. Shutdown input connected to the ground will not allow the driver to work. It has around one second soft-start so leaving it free or connecting to 12V will allow using modulation input after this time period. Shutdown input CAN NOT be used as TTL modulation. We recommend the use of power cables with cross-section of at least 4 mm2.Protection Due to high current flowing trough the paths we minimalized the voltage drop on the driver and there is no reverse polarity protection. We strongly recommend using LASORB protection device mounted close to the diode. The driver's body is isolated from all signals of the driver and can be mounted directly to the metal heatsinks or other metal parts. The analog input is protected by a 5V1 Zener diode on occasion there appears the voltage higher than 5V. Despite everything, this input should not be used with higher voltages.
