How to Choose the Right Power Supply for Your Fiber Laser Cutter

To ensure stable operation and high performance of a fiber laser cutting machine, proper electrical configuration is essential. Here are the key power requirements to follow:

⚡ 1. Power Supply

Most fiber laser cutter rated 2kW, 3kW, or higher require a three-phase 380V (±10%) 50/60Hz power source.

Smaller models, such as 1500W or 2kW, can operate with a single-phase 220V supply.

🔌 2. Grounding and Safety

The machine must be properly grounded to prevent electrical interference and ensure safe operation.

Always use a stable voltage to avoid fluctuations that may affect cutting quality or damage the laser source.

In areas with unstable power grids, it is recommended to install a voltage stabilizer or UPS (Uninterruptible Power Supply) system.

⚠️ 3. Wiring and Installation

Power cables must meet the rated current specifications of the machine.

Separate wiring should be used for the control cabinet and the laser source to prevent signal interference.

All electrical wiring and inspections should be performed by qualified electricians for safety and reliability.

💡 Stable power means stable cutting.

Always follow the manufacturer’s power specifications to keep your laser cutting machine operating safely, efficiently, and reliably.
