Intermediate Frequency AC Power Supplies The IFP series is AC Power Supplies with a constant 400Hz output frequency and adjustable output voltage, based on the same technical principle as the adjustable AC power supplies of SPWM method, IGBT module design and D/A conversion technology. The difference is that the output frequency of the Intermediate Frequency AC Power Supplies is constant at 400 Hz, it is a replacement product of unit type variable frequency power supplies with higher output frequency accuracy and stability.

The output power of single-phase Intermediate Frequency AC Power Supplies ranges from 500VA to 200KVA, and the output power of three-phase Intermediate Frequency AC Power Supplies ranges from 3KVA to 600KVA. The output voltage of both types can be divided into 0 ~ 150Vac, 150 ~ 300Vac with 400Hz fixed output frequency. This series of AC power supplies are featured for high precision, stable output, high display resolution, low waveform distortion and complete protection functions.
Through the friendly operation panel, you can read the output data such as output voltage, output current, output power, power factor, etc., providing accurate data records for your test, and can add RS485 interfaces as standard, following the MODBUS-RTU international communication protocol, which can realize remote control and operating status monitoring of the power supplies, Currently, the Intermediate Frequency AC Power Supplies are mainly used for aircraft and mechanical equipment, radar, navigation and other military electronic equipment and other occasions that require 400Hz intermediate frequency output.
The number of industrial robots in Zhejiang ranks first in the country
On January 19, the Zhejiang Provincial Academy of Social Sciences released the "Zhejiang Blue Book" for 2018. This comprehensive report is divided into seven volumes, covering social, economic, ecological, political, cultural, market, and information economy aspects. Notably, the information economy volume marks a first in the series, offering an in-depth analysis of Zhejiang’s evolving socio-economic landscape.
According to the report, since 2017, Zhejiang has maintained a steady growth trajectory by adhering to the principle of stability with progress, implementing new development concepts, and focusing on supply-side structural reforms. These efforts have led to a more pronounced stable economic trend, with major economic indicators outperforming the national average.
In 2017, the province's GDP was expected to grow by approximately 8.0%, significantly higher than the national average of 6.8% during the same period. In the first three quarters, Zhejiang’s GDP reached 3.6958 trillion yuan, reflecting a year-on-year increase of 8.1%. This growth highlights the province’s resilience and dynamism in a slowing national economy.
The rise of the internet-driven economy, particularly e-commerce, has been a key driver of Zhejiang’s growth. The province has 41 counties ranked among the top 100 e-commerce counties nationwide, along with 51 Taobao Townships and 506 Taobao Villages—both leading the country. With the world’s largest SME e-commerce platform and online retail infrastructure, Zhejiang continues to lead in digital commerce. In the first three quarters of 2017, sales through designated-size online platforms increased by 30.2%.
Business creation also saw significant growth, with 284,000 new enterprises established in the first three quarters, a 25.4% increase compared to the previous year. Additionally, 557,000 new individual businesses were registered, showing a 15.2% growth. On average, over 1,040 new companies and 2,040 individual businesses were added daily.
The information economy has emerged as a key driver of Zhejiang’s economic growth. As China transitions toward a more tech-oriented economy, Zhejiang has positioned itself as a national model. The province leads in industrial automation, with about 11% of the country’s industrial robots located there. In the field of internet finance, Ant Financial has become a leading innovator, contributing to Zhejiang’s status as a hub for financial technology.
Zhejiang is also at the forefront of sharing economy initiatives, which are playing a crucial role in promoting the internationalization of cities like Hangzhou. The province has developed a strong ecosystem of sharing-based businesses, spanning consumer experiences, productivity tools, and even medical services.
With the global economy expected to see a 25% increase in Zhejiang’s share from 2015 to 2025, the province is well-positioned to continue its upward trajectory. Through strategic cooperation within the Yangtze River Delta and active participation in the “Belt and Road†initiative, Zhejiang is expanding its influence both domestically and globally.
