405nm 445nm 450nm 520nm Laser Drive 200mW-3W 12V Driver for RGB Laser with TTL

Specification:

Circuit Control: 12V step-down circuit, constant current output (current and voltage are adjustable)
Output Specifications: Max 3A
Scope: 200mW-3W 405nm/445nm/450nm/520nm red, green and blue laser drive power
Dimensions: 29x49mmx15.5mm(WxLxH)
Input voltage: 8-14V
Feature:
This new high driver circuit adds 5521DC-line ports, to solve the defects of listing stage laser field drives whic are not allowed to be directly connected to the power supply.Of course this is not just for the laser-driven, but also can be used for all kinds of buck constant current source.
Most of drivers are only for DC without rectifying.But AC-DC both can be used on this driver,regardless of the positive and negative input.So greatly improving the non-professional user convenience.
