Introduction
Beijing Yunengxin Company, founded in the 1990s, is an equipment and professional technical service company registered in Zhongguancun Science and Technology Park. The company has the right to import and export goods, with a registered capital of 10 million yuan. As of the end of the year A total of 400,000 kilowatts of Hitachi inverters have been provided to the society. It has made due contributions to the motherland’s clear water and blue sky, energy saving and consumption reduction. The company is the earliest agent for Hitachi inverters, Hitachi and other industrial control products, and a Hitachi authorized inverter technical maintenance center.
The company's products include Hitachi
, Hitachi high and low voltage inverters, Hitachi
, Hitachi air compressors, and other high-quality industrial control products and parts companies in Europe, the United States, Japan, South Korea and Taiwan. Self-developed various types of frequency conversion energy-saving control cabinets and other products.
The services provided by the company are entrusted by customers to provide consulting, repair, maintenance and other on-site services for the inverters and other industrial control equipment used by customers.

Series
High starting torque, efficient operation and simple debugging, It can easily debug complex motor fixed parameters and achieve the above high starting torque.
Used in elevators, the torque can be ensured even if the speed is commanded. It is most suitable for elevators such as cranes that require instantaneous torque from low speed when starting.
The overcurrent suppression function (high-speed current control) and overvoltage suppression function greatly speed up the internal calculation speed of the inverter and greatly improve the current control performance. The overcurrent suppression function and overvoltage suppression function do not need to adjust the necessary acceleration according to the load. , deceleration time, reducing the occurrence of tripping
A button can realize the emergency stop of the inverter output without passing the frequency conversion, and shutting down the output through the hardware loop can realize a safe and reliable emergency shutdown action
Micro surge voltage suppression function ( Applied for patents in Japan, the United States, South Korea and other countries)
Expanded models with built-in regenerative braking circuit (below)
Equipped with noise filter
The installation of built-in zero-phase reactor complies with the national Ministry of Transport specifications Requirements
The use of long-life parts, fans, capacitors and other devices must have product lifespans of more than 10 years, and the lifespan diagnostic function will issue lifespan warning signals. Receive signals for repair before a fault occurs
Analog input disconnection detection function
Smart input terminal response time setting
Smart input terminal pulse reading
Programmable function steps to save costs
Terminal strips are interchangeable with the series.
