High efficiency AC input 20A 5V laser driver

Time : 2015-08-26 17:05Source :analogtechnologies Author : Analog Click :

AAS20A5V is a kind of high efficiency AC input 20A 5V laser driver, which is used to drive 0~20A laser diode. 0~20A output current can be set by setting 0~2.5V analog voltage. It has been widely used for driving fiber diode, diode laser rod and so on. The physical figure of AAS20A5V laser driver is shown in Figure 1.

There are over temperature protection and short circuit protection inside. When the inside temperature exceeds the limit 90°C, the laser driver will shut down automatically. And when the temperature returns to the normal temperature range, it will restart. If there is a short circuit at the output, the internal protection circuit will cut off the output.

In order to keep the output current as a preset value, the output voltage is automatically set between 0V~3.5V. A potentiometer can set the maximum voltage between 2.6V and 3.5V. If the output is up to the preset maximum value, it will always keep the maximum value, and the output current is no longer limited to the set values. In order to ensure the control loop work normally, it will be monitored in real time by the internal circuit.
