Single-phase voltage and frequency stabilization power supply
This power supply employs advanced sinusoidal pulse width modulation (SPWM) IGBT high-frequency inverter technology and features an internal AC–DC–AC topology, which completely eliminates grid interference and ensures a pure output waveform. It offers a wide voltage and frequency regulation range, high accuracy, lightweight construction, compact size, and an output equipped with an isolation transformer; thus, it can seamlessly integrate with generators to form a high-quality uninterruptible power supply (UPS) system.
Key technical parameters of single-phase voltage and frequency stabilization power supplies:
- Input voltage: 130–280 V
- Input frequency: 35–70 Hz
- Output voltage: 220 V ±0.5%
- Output frequency: 50 Hz ±0.01%
- Waveform distortion: <1%
- The isolation transformer provides an output that is both safe and reliable.
- Features automatic protection and alarm functions against output overvoltage, overcurrent, overload, overheating, and short circuits.
- The efficiency exceeds 90%, offering a wide range of applicable loads—capable of handling inductive, capacitive, resistive, or any combination of these load types.
- The dynamic response is extremely fast; when the load varies from 0% to 100%, the steady-state response time is <0.1.
- Please specify the input and output voltages and frequencies when placing your order.
Application scope of single-phase voltage and frequency stabilization power supplies:
- Railway, aviation, and maritime systems
- Precision testing of medical electronic devices
- Power supply for imported electronic and electrical equipment
- Testing of exported electronic and electrical products
- CNC machine tools, light industry and textile manufacturing, automated production lines
- Provide supporting components for the generator plant to construct a high-performance uninterruptible power supply (UPS) system.
