LASERPWR ES150 ESA150 130-180W CO2 Laser Power Supply

The LASERPWR ES150 / ESA150 is a high-voltage CO2 laser power supply designed for 130W to 180W glass CO2 laser tubes. It is suitable for laser engraving, laser cutting, marking, and die-cutting machines that require stable high-voltage output and reliable tube ignition.

Built for industrial laser machine applications, this power supply supports a wide AC input voltage range and uses active PFC technology to help maintain stable performance even when input power conditions vary. Its fast response speed, strong output capability, and built-in protection functions make it a practical replacement or upgrade power supply for compatible CO2 laser systems.

The ESA150 model also includes display and control features that help with setup, testing, and maintenance. With digital current display, light output indication, water protection signal display, built-in potentiometer, and manual test button support, it gives technicians clearer visibility when checking machine operation.

Stable Power for CO2 Laser Tubes

The ES150 / ESA150 is designed to drive high-power glass CO2 laser tubes in the 130W to 180W range. Stable output is important for consistent cutting depth, engraving quality, and laser tube performance during long production jobs.

It is suitable for CO2 laser cutting machines, engraving machines, marking machines, portable cutting beds, and similar equipment using compatible glass laser tubes.

Wide Input Voltage Compatibility

The power supply supports AC90–264V input with 47–63Hz frequency compatibility. This wide input range allows it to work in different electrical environments while helping reduce issues caused by unstable input voltage.

The active PFC circuit improves power factor and helps the unit operate more efficiently under load.

Fast Response and Accurate Control

With a response speed of ≤1ms, the power supply can react quickly to laser control signals. This is important for engraving and cutting applications where the laser output must start, stop, and adjust rapidly according to the machine controller.

Laser power can be controlled using a 0–5V analog signal or 5V PWM signal, making it compatible with many common CO2 laser machine control systems.

Built-In Display and Manual Adjustment

The ESA150 version includes display and control features for easier monitoring and maintenance. The digital display can show current value, light output status, and water protection signal status, helping users identify whether key operating signals are normal.

The integrated potentiometer allows manual current adjustment, while the test button provides a convenient way to check laser output and power supply function during servicing.

Protection and Cooling

The power supply includes open-circuit protection to help protect both the power supply and laser tube. Forced air cooling helps manage internal temperature during operation, supporting more stable performance in workshop and production environments.

Correct installation, grounding, wiring, water protection connection, and cooling airflow are essential for safe and reliable operation.
