XSF13 20-80kVA Stabilized Frequency Converter Power Supply

Product overview 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.
