Note
【1】There are a total of 64 semiconductor laser tubes inside the laser, each of which is connected in series to form a channel, a total of eight strings。
【2】Please store in a non-condensing environment
【3】The working temperature of the laser refers to the temperature of the base plate. The laser can work in the environment of -40~+65 degrees, but the output power will be different at different temperatures. Generally speaking, the output power of the laser is greater than 70% of the nominal value at 65 degrees.

Instructions for use u
When the laser is working, avoid laser exposure to eyes and skin。uAnti-static measures must be taken during transportation, storage and use. Short-circuit protection is required between pins during transportation and storage。uFor lasers with a working current of more than 6A, please use welding to connect the leads.。uBefore operating the laser, make sure that the fiber output end is properly cleaned. Follow safety protocols to avoid injury when handling and cutting fibers。uUse constant current power supply to avoid surge when working。uShould be used at rated current and rated power。uWhen the laser is working, it is necessary to ensure good heat dissipation。uOperating temperature-40°C~ 65°C。ustorage temperature-20°C~+80°C。
