Professional Recommendations from Foster Laser
As an experienced and professional laser equipment manufacturer, Foster Laser is committed to helping customers select the most suitable power supply for fiber laser cutting machines.
Understanding power requirements in advance ensures smoother installation, safer operation, and long-term machine stability.
Three-Phase Power – The Preferred Choice for Industrial Cutting
For medium- and high-power metal fiber laser cutting machines, three-phase power is the industry-standard configuration and the most reliable solution.
In industrial production scenarios where efficiency and stability are paramount, three-phase power has long been the preferred and most widely used power solution for fiber laser cutting
machines. For medium and high-power cutting tasks, it is even the irreplaceable standard configuration.
Foster Laser Recommendation:
Most fiber laser cutting machines with 2kW, 3kW, and higher power are designed to operate with three-phase 380V (±10%), 50/60Hz electricity.
Why Three-Phase Power Is Strongly Recommended:
Supports the high electrical demand of laser sources, motion systems, and industrial chillers
Ensures stable voltage output during long-term, high-load production
Reduces power fluctuation risks and improves cutting consistency
Helps protect core components and significantly extends equipment lifespan
For these reasons, Foster Laser’s standard industrial fiber laser cutters are optimized for three-phase power supply, ensuring reliable performance even in continuous production
environments.
Single-Phase Power – Flexible Option for Entry-Level Users
We understand that not all customers are in large industrial plants with complete three-phase power facilities. For small workshops, startup enterprises, or on-site construction scenarios with
limited power conditions, Forster Laser specially launches low-power laser cutting machine models that support single-phase 220V power supply, providing more flexible choices for small-
batch production and temporary operations.
To support customers with limited electrical infrastructure, Foster Laser offers single-phase 220V solutions for selected low-power laser cutting models.
Applicable Models:
Some 1500W and 2000W fiber laser cutting machines
Customized configurations based on local power conditions
Ideal for:
Small workshops and newly established factories
Sample cutting, prototyping, and light production tasks
Areas without access to industrial three-phase electricity
Important Notice:
Single-phase power machines require stable voltage conditions. Foster Laser strongly recommends using a voltage stabilizer and avoiding long-term full-load operation to ensure safe and
reliable performance.
How to Choose the Right Power Supply
Before placing an order, Foster Laser advises customers to evaluate the following factors carefully:
Current laser power requirements and potential future upgrades
Planned production capacity and working hours
Local power grid stability and available voltage
Compliance with local electrical safety and grounding standards
Proper power planning not only reduces installation risks but also helps avoid costly upgrades and downtime in the future.
Installation Safety Guidelines from Foster Laser
To ensure smooth installation and long-term safety, please confirm that:
Power voltage and frequency fully match machine specifications
Independent circuit breakers and proper grounding are installed
Electrical wiring complies with Foster Laser’s technical standards
For special or complex power environments, Foster Laser provides professional technical consultation and customized power solutions tailored to customer needs.
Final Thoughts
Different fiber laser cutting machines require different power configurations.
Selecting the correct power supply is a key factor in achieving stable operation, high cutting precision, and long service life.
Foster Laser continues to deliver safe, efficient, and reliable fiber laser cutting solutions—empowering manufacturers worldwide with confidence and performance.
