New CO2 Laser Power Plate Engraving Machine Beauty Package Stamp with High Voltage Crossflow |

Laser Power Supply for 40W Seal Engraving Machine The power supply adopts zero current half bridge soft switching circuit, which makes the power supply efficient and fast response. It is easy to cooperate with laser tubes from various manufacturers. Port control is simple, adapted to high and low level signals. TTL level can be used to control the start and stop of laser. At the same time, abnormal protection switch is added to detect whether the external water, ventilation and so on. Laser power regulation can input both analog signals of 0 to 5V and PWM signals to control laser power. Power supply has open-circuit protection function: in the case of good grounding protection, power supply can work in open-circuit state for a short time, so as to avoid the damage of laser power supply caused by the bursting of laser tube. AC input voltage AC220V or AC110V DC input voltage DC300V or DC150V AC input frequency 47 ~ 440Hz Voltage output 22KV Current 23mA depends on the laser tube made by different manufacturers. Efficiency 91% 130% of overcurrent protection current Open circuit protection; short time; Structural fan cooling High-level control voltage range 3V Low-level control voltage range 0.8V Working Temperature - 30 ~65 Relative humidity 20-85% RH#40; no condensation; Voltage-withstanding input and output AC1500V1 minute 10mA Input case AC1500V1 minute 10mA
