Constant Current Source Adjustable Current Source Low Temperature Drift Laser

Description: Description High Precision Constant Current Source Module Adjustable Current Source Low Temperature Drift Laser Description: - This high-precision precision current source module is manufactured using imported high-precision components, utilizing deep negative feedback technology and built-in low-temperature drift wafer resistance sampling (1 ohm) to ensure stable constant current output. Its current stability can reach 99.99%, and the load adjustment rate is only one thousandth. - Adopting an aluminum substrate design, it has fast heat dissipation and effectively reduces temperature drift. In addition, the module has an enable control function and a current detection output (differential) interface, and the output current can be adjusted through the high-precision imported potentiometer on the module. - This module can drive light sources such as laser diodes (LD) and light emitting diodes (LED) to ensure high stability of their output. At the same time, it can also be used to drive bridge circuits such as weight, flow rate, and wind speed, and is suitable for systems such as biological fluorescence detection, chemiluminescence detection, and water quality detection. - The compact size and clear interface design enable users to easily integrate it into their own systems.

To achieve optimal performance of the module, the supply voltage should be slightly higher than the voltage across the load (2V). The specific calculation method is as follows: VIN=IOUT * RL+2 For example, if the set output current is 50mA and the connected load is 100 ohms, the voltage at both ends of the load is 5V. Choosing a power supply voltage of 7V can maximize the performance of the module. Precaution: - To avoid excessive current from burning out the load, you can first use an ammeter to measure and adjust the output current before connecting the load. - To avoid unnecessary interference, it is recommended to use a linear power supply, which should not exceed 16V. - It is recommended to use good wire to observe the effect. Poor contact or inferior wire may cause signal attenuation or excessive noise. - It is recommended to use low resistance wires for the output line, otherwise it may cause excessive line loss and unstable current output. - TP and TN must not be connected to GND, otherwise it is easy to burn out the drive circuit. FAQ: Q: How to adjust the output current size? A: The output current is adjusted by a potentiometer. Q: Why can't the load output 100mA when connected to a 250ohm resistor? A: The maximum load capacity of the module is 100ohms. It is recommended to reduce the load resistance before testing. Q: Can modules directly drive coils? A: Modules can drive inductive loads such as coils. Q: Can I output AC constant current? A: No, the module is a DC current source, and the output current is adjusted by a potentiometer.
