Xianming Laser Fiber Laser Cutting Machine Power Requirements Guide
When selecting and installing a fiber laser cutting machine, power supply configuration is one of the most important factors to consider. A stable and suitable electrical system is essential for safe operation, cutting performance, and long-term machine reliability.
As a professional laser equipment manufacturer, Xianming Laser provides the following guidelines to help customers clearly understand the power requirements for laser cutter machines, including the use of three-phase and single-phase power.
Three-Phase Power: Standard Configuration for Medium and High Power Machines
In industrial applications, three-phase power is the most common and recommended solution for fiber laser cutting machines.
Xianming Laser Notice:
Most fiber laser cutting machines with 2kW, 3kW, and higher laser power require a three-phase 380V (±10%) 50/60Hz power supply.
Why Three-Phase Power Is Required
High-power laser sources, servo motors, and chillers require higher electrical load capacity
Three-phase power provides better voltage stability for continuous operation
Helps protect the laser source and electrical components, extending service life
For this reason, Xianming Laser’s standard industrial fiber laser cutting machines are designed to operate with three-phase 380V power.
Single-Phase Power: Optional Solution for Low-Power Models
For customers with limited power conditions, Xianming Laser also offers single-phase 220V power options for selected low-power cutter machines.
Applicable Range:
Some 1500W or 2kW low-power fiber laser cutting machines can operate with a single-phase 220V power supply.
Typical Applications
Small workshops or startup factories
Sample cutting or light-duty production
Regions without access to industrial three-phase electricity
Please note that single-phase machines require stable voltage conditions. A voltage stabilizer is strongly recommended, and long-term full-load operation should be avoided.
Power Selection Recommendations
Before confirming the power supply for your fiber laser cutting machine, Xianming Laser recommends evaluating:
Laser power level (1500W / 2000W / 3000W and above)
Future production expansion or power upgrades
Local electrical infrastructure and voltage stability
Proper grounding and industrial safety standards
Proper planning can help reduce installation risks and future modification costs.
