Product Details 1 - It has excellent protection function: the 300W laser power supply has open circuit protection, which allows the high-voltage laser power supply works in an open circuit state for a short time, thereby avoiding damage to the CO2 laser tube.
2 - The laser powersupply's control is simple.
And the 300W laser power supply can use 0-5V analog signals or PWM signals for laser power control.
3.300W laser power supply uses ordinary H/L/P/G/IN/5V ports to receive control signals.
4 - The 300W laser power supply has stable performance: each laser power supply has undergone multiple testing procedures and 24-hour aging at high temperature (52-55 degrees Celsius) under full load, ensuring the stability of each CO2 laser power supply.
5 - The 300W laser power supply has good compatibility: This high-voltage laser power supply can drive foldedCO2 300W laser tubes such as RECI, SLW, Yongli, SPT, etc In addition to this function, the high-voltage laser power supply also has strong functional adaptability, fast response speed, and good cutting effect.
6 - The 300W laser power supply is easy to control: it uses high or low level for control.
Using TTL level control, it can achieve fast start and stop.
At the same time, the high-voltage laser power supply is equipped with a protective switch, which is tested through external water and ventilation
7 - It uses the latest silicon carbide to replace traditional transistors.
Silicon carbide has high efficiency, low heat generation, and low failure rate.
This makes the laser power supply more suitable for long-time uninterrupted running in high temperature environments without any malfunctions.
8 - Silicon carbide reduces circuits's quantity, which reduce failure rate and keep consistency in output parameters.
It improves high-power cutting effect of CO2 laser cutting machine
9 - It adopts surface mount assembly technology, fully automated and standardized production lines.
Besides,, it also uses high-definition cameras to detect circuit boards, assembly components, and soldering effects.
These three methods reduce the unqualified power supply's possibility caused by human error.
10 - It uses silicone tubing to wrap the output high-voltage cable, which prevents electric sparks from splashing.
It can protects operators and equipment and enable the laser power supply works normally in humid environments
11 - It can support input voltages of AC90-260V or DC 280-320V.
So this 300W CO2 laser power supply can be installed on mobile vehicles.
Batteries can be used to power it.
The usage conditions are convenience and flexibility It can be used for special CO2 laser applications.
Special input 250-350VDC voltage range can be customized, it uses a voltage
regulator to reduce the default minimum input voltage from 280V to 250V.
At the same time, it uses a larger power transistor to increase the maximum input voltage from 320V to 350V.
Note: that 350V is already the upper limit value If the input voltage is greater than 350V, the electronic components inside the power supply will be burned out.
12 - The 450/600/750W or other special paramter's CO2 laser power supply can be customized on client's requirement.
13 - This 300W laser power supply can be used to drive most brand 300 watt CO2 combined beam laser generator or 300watt CO2 folded CO2 laser tubes on laser die cutting machine.
Optional LCD Display
An optional external LCD display is available to provide real-time visibility of operating current, system status, and fault diagnostics.
The display is equipped with a rotary control knob that allows users to conveniently and precisely adjust the output current.
The standard configuration supports a single control channel, while 4-channel and 8-channel versions are available for applications that require multi-channel monitoring or centralized control.

- Business Description: Jinan Ruby Laser Technology Co.,Ltd is main laser power supply manufacturer which was established at 2015 - From then on ,it has more than 10 years experience to research & develop, produce and sell RUBYLASER brand CO2 laser power supply,YAG pulsed xenon lamp power supply and special power supplies for UV/RF CO2 laser marking machine.
At present, our laser power supply has four series products(ZS series,ESseries,RS series and ICO series).
ZS series laser power supplies are used for CO2 laser tube,ES series laser power supply is for UV laser marking machine,RS series laser power suppply is for RF CO2 laser marking machine and ICO series laser YAG pulsed exnon lamp power supply is used on laser welding machine for jewelry welding or mold repair.
Based on client’s using feedback and’ innovation in electronic technology,the company developed LCD display screen for CO2 laser power supply.
Now ZS series power supply has 40W/50W/60W/80W/100W/150W /200W/300/450W models and ICO series power supply has 80W/100W/200W/400W single or double lamps model.
Since its establishment,Jinan Ruby Laser Technology Co., Ltd attaches great importance to the quality of laser power supply to establish RUBYLASER brand’s good reputation in domestic and foreign markets In order to realize this goal, it has an experienced management team and skilled technical workers.
And all accessories are purchased from United States, Japan,France, Taiwan and China’s well-known companies, some electronic components have UL,CE,CCC,TUV,SA certification.
The laser power supplies are also produced accordance with the requirements of ISO9001 quality system.
At present, all CO2/YAG laser power sources have obtained CE certification, and they are used by the main laser engraving machine, laser cutting machine,laser marking machine and YAG laser welding machine manufacturers.
Excellent quality, reasonable price and professional pre-sale and after-sales service team make RUBYLASER power supply become one of three great power supply manufacturers in China.
RUBYLASER CO2 lase power source’s feature,specification,ins tallation size, operation method and wiring connection method are completely same with other brands' power supplies, so PS sereis laser power supply can replace these three brands power supplies.
Now Jinan Ruby Laser Technology Co., Ltd 's laser power supply have occupied about 30% of the Chinese market
