Are you looking for a powerful yet easy to integrate laser driver for your project or product that won’t break the bank? Well look no further!
The J Tech Photonics High Power Laser/LED driver is designed with features, protection, size, and cost in mind.
This is the fourth generation of the popular High Current Laser Diode Driver series. We designed this new generation to follow the federal guidelines for safety compliance for high power Class 4 laser operation. This includes the use of a key enable switch, safety interlock system, power off reset, and laser LED indicators. All of these features make for a safer laser operation and will comply with federal laws regulating such operations.
At the heart of the product are laser trimmed parallel regulators to give constant current without the large temperature dissipation of other regulators. Couple this with inherent safety features like soft starting, current isolation, reverse protection, ESD protection, and thermal shutdown control and you have all you need in a small package.
The high power laser diode driver is cost effective and easily integrated into industrial, research, or enthusiast projects and products. The driver can be operated in CW mode or in Input Control Mode to be interfaced to remote electronics. This design uses digital isolators for super fast response and input range while protecting the laser from deadly ground loops. The board has screw terminal connections as well as Molex mini-fit Jr. connectors for easy connections to external equipment for control and the laser diode output.
2.5 Amp Version
This version of the popular High Current Laser Driver offers up bigger regulators, bigger power adapter, more capacitance, more resistors, and more options for current limits. It includes the OEM Power Connector with Cable 6′ 18AWG – Straight to easily connect to a DC power supply of choice. There is a 3 volt drop across the regulators, so choose a power supply to be above your laser diode voltage plus at least three volts.
This driver will provide 2.5 amps of constant regulated and protected current to the diode. Configurable current limits with jumpers for 0.5, 1.0, 1.5, 2.0, and 2.5 amp settings and adjustable output with an analog trim pot. It also can be remotely controlled with an opto isolated input with a super huge range of acceptable voltages for turning your driver on and off. Does your equipment in your project or system that you want to interface with have backwards logic? No problem! There is a jumper for choosing inverted or non inverted logic as well! Perfect for integrating into any final product or project.
