Its size allows for mounting it in small devices such as compact laser projectors. Thanks to an included radiator you do not need to worry about heat dissipation, drilling and isolation of power transistors from the heatsink. It is a fully functioning component ready to be mounted in laser devices. We intentionally resigned from a plug connector powering the circuit because experience shows that soldering the wire is the only sure way to avoid the problems associated with oxidation of contacts and arcing, particularly when a current of 15 A can flow through the wires. Despite its small size, the driver is able to work with thermocouples (Peltier modules) such as 12706, 12708, 07113, and many others that draw up to 15 A of current. Despite high current, thanks to using PWM the controller does not heat up. Used PID algorithm learns the behavior of the system, hence quicker reacts to changes in temperature and provides higher accuracy of stabilization. The driver easily handles all laser diodes of up to 5W, and at the customer's request it is possible to customize the driver up to 10A version. Separate laser diode supply voltage input and TEC input enable the selection of any components the driver can work with. Analog input allows for the modulation of the current flowing through the diode up to 200kHz. Two potentiometers are used to set the values of maximum diode current and bias current. The third potentiometer is responsible for setting the setpoint temperature in the range of 0 to 40 degrees Celsius. The possibility to power laser diodes of any wavelength and control the Peltier modules with a rated voltage from 3.3 to 36V and current up to 15A make this driver truly unique and extremely versatile. At another auction, you can find the same driver but with three separate channels to control the laser diodes; it is the perfect solution for RGB projectors and laser systems. Attached to the controller is a high-quality set of D-SUB (25 pin) connector which are rated 5A/pin. On the customer's request, D-SUB socket may not be soldered in.Recommendations and requirements The minimum diode input voltage should be higher or equal to 5V, in other situations it is given by the formula: Vin = 0,4* I + Vd + 0,6V Vin - input voltage Vd - diode working voltage I - desired maximum current 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. You should be very careful not to cause short circuit between the + (VCC) of the power supply and ? (GND) of the analog input, as a thin GND analog path can be irreparably damaged. We recommend the use of power cables with cross-section of at least 0.5 mm2. At another auction you can find the same driver but without a heat sink. This reduces the shipping and production costs, but requires the ensuring of an adequate cooling for the driver. If it is not available, please contact us and we will prepare the auction.Protection The circuit responsible for powering a laser diode is protected against reversed polarity. High current Schottky diode of an extremely low forward voltage secures the laser diode against connecting reversed voltage with the aim of protecting frequently the most expensive part of the entire device - a laser diode. In turn, the low forward voltage does not cause excessive heat loss during normal operation. 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. A microcontroller ensures the proper operation of the entire system. When the temperature reaches above 50 degrees Celsius, it turns off the laser diode supply circuit and does not allow for its further load, it also goes into failure state (blinking LED) until the restart. The microcontroller will operate in the same way in case of connection loss with a thermistor measuring the temperature. The driver is fitted with a two-second softstart designed to protect the laser diode against switch-on effects. Shipping Items are shipped withing three working days.
