Static frequency converter
The ACME series of programmable AC frequency converter use a DSP/FPGA processor as its core and adopt PWM technology and sinusoidal pulse width modulation. Single-unit power range from 500VA to 2000KVA, and the output can simulate different voltages and frequencies worldwide, meeting the load requirements of various industries. The power supply uses an isolation transformer output, ensuring safety and reliability while increasing overall stability. It features strong load adaptability, high-quality output waveform, easy operation, small size, and light weight. It also has comprehensive protection functions against short circuits, overcurrent, overvoltage, and overheating to ensure reliable operation.
Product Description
Technical features
The ACME series of programmable frequency converter power supplies are designed and manufactured specifically for the voltage and frequency conversion testing and power supply of imported and exported electrical products. They can provide standard grid voltages and frequencies from around the world, with stepless digital adjustment of output voltage (0-300V) and frequency (45-65Hz). The waveform is stable and clean, eliminating grid interference, and is suitable for voltage and frequency conversion testing of exported electrical products, as well as various precision tests in laboratories and metrology rooms. This series integrates high-precision voltage, current, and frequency displays, offering a high performance-price ratio. It adopts a high-power IGBT module design, reducing circuit complexity, improving product stability, reducing power loss, and continuously increasing single-unit capacity. Furthermore, this series of power supplies use multiple ultra-isolation transformers to completely isolate the mains power from the load, increasing the overall functionality of the unit.
