Overview
XSF13 Stabilized Frequency Converter Power Supply | For Single-Phase Sites Running Three-Phase Equipment
The XSF13 series is designed for customers who only have single-phase power on site but need to run three-phase industrial equipment, such as a 3000W laser cutting machine or a 15kW air compressor. It converts 220V single-phase input into stable 380V three-phase isolated output, helping users install higher-power equipment without immediately upgrading the entire site power supply.
This listing covers XSF-13020, XSF-13030, XSF-13050, and XSF-13080 models, with rated capacities from 20kVA to 80kVA. The system uses SPWM sine-wave pulse-width modulation, high-frequency IGBT static inversion, transformer-isolated output, and dual-loop control for stable voltage, stable frequency, and low waveform distortion.
Please note that this image is for a single-phase 50KVA product; other models can be referenced in this image.
Best For
- Customers who only have 220V single-phase power but want to run a 3000W fiber laser cutting machine.
- Workshops that need to power a 15kW air compressor from a single-phase power source.
- Small factories, garages, farms, or remote workshops where three-phase utility power is unavailable or expensive to install.
- Industrial equipment that requires stable 380V three-phase output from 220V single-phase input.
- Testing, inspection, aging tests, and production environments requiring adjustable output frequency.
Key Features
- Single-phase to three-phase power solution: Converts 220V single-phase input into stable 380V three-phase isolated output.
- Suitable for laser cutting setups: Helps customers run 3000W laser cutting machines in workshops without existing three-phase power.
- Air compressor support: Suitable for properly sized 15kW air compressor applications after load confirmation.
- Input and output isolation technology improves power safety and reliability.
- SPWM sine-wave modulation provides fast response and stable output waveform.
- High-frequency IGBT static inverter design helps reduce size, weight, noise, and power loss.
- Instantaneous-value and RMS dual-loop control improves control accuracy and waveform quality.
- Three-phase independent H-bridge topology supports stronger three-phase unbalanced-load capability.
- Output voltage is adjustable online, and output frequency can be set for different test conditions.
- Built-in short-circuit, overcurrent, overload, and power-device overtemperature protection.
- 10-inch color LCD touch screen for voltage, frequency, current, and power display.
- RS-485 and RJ-45 communication ports with Modbus protocol.
Recommended Applications
| Customer Situation | Typical Equipment | Why XSF13 Helps |
|---|---|---|
| Only single-phase power is available in the workshop | 3000W fiber laser cutting machine | Provides stable 380V three-phase output from 220V single-phase input after capacity confirmation. |
| No three-phase utility power at the site | 15kW air compressor | Allows three-phase compressor operation when the selected model capacity matches the compressor load and starting requirements. |
| Equipment testing requires different frequencies | Industrial machines, motors, test benches | Supports 50Hz, 60Hz, and 45-65Hz adjustable output frequency. |
| Mixed industrial loads need stable isolated power | Resistive, inductive, and rectifier-type loads | Transformer-isolated output and SPWM control improve stability and waveform quality. |
