High efficiency AC input 20A 5V laser driver

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.

High efficiency laser power supply

AAS40A3.5V is a kind of laser power supply, which is designed for driving 0~40A laser diodes. It can set 0~40A output current by setting 0~2.5V analog voltage. There are short circuit and over temperature protection circuit inside. This laser power supply has high efficiency, more than 76%. It saves energy and has low temperature rise. The physical photo of AAS40A3.5V laser power supply is shown in Figure 1. 

 

Figure 1. The physical photo of AAS40A3.5V laser power supply

AAS40A3.5V2 laser driver comes with 2.5V high stability reference voltage, which is utilized to set the output current and maximum output voltage. At the same time, the reference is also used as the reference of external ADC and DAC to monitor or set the laser current and maximum voltage, the so-called compliance voltage. 

There are many other series laser power supplies in our company (ATI), such as AAS30A5V, AAS20A5V and so on. Otherwise, we can also customize a specified laser power for customers. Before our products enter into the market, all of them go through testing process in order to ensure the quality.

TEC modules

TEC modules (thermoelectric coolers) are designed for cooling and heating, depending on the direction of direct current. When the current flows from the negative direction to the positive direction, TEC will start to cool, and conversely, it will start to heat. TEC modules have been widely used for controlling the temperature of laser system, refrigerator cooling system, air conditioner, computer CPU and so on.
