Features
The core components are all imported, adopting the sixth generation IPM module from Mitsubishi, which has stable performance, long service life, strong protection functions and convenient replacement and maintenance.
Adopt the central processor DSP28335 chip from American TI Company, respond quickly and accurately, and provide stable and clean power for the load to provide protection.
The whole machine adopts modular design and plug-in design, which is convenient for maintenance and reduces the hidden cost of machine failure to repair.
According to the product configuration conditions, adjustment the system usage mode: DC(Battery/Solar) priority or AC mains bypass priority can be set.
Two kinds of start mode: Reduction Voltage Start and Variable Frequency Start. Customers can set start mode according to the type of their load. This function is very convenient for users and also reduce frequency converter’s usage, which reduced the cost of equipment investment, easy to connect wires and control.
The output voltage can be set between -40 % to +20 % of rated voltage. And the output voltage is very accuracy ±1%.
The DC input voltage range can be set. Over-voltage point, under-voltage point, over-voltage recovery point, under-voltage recovery point all can be setting via the LCD panel.
Output AC Power is suitable for all types of electrical equipment, CNC machines, electric tools, motors, pump and air conditioner etc. It has higher efficiency and higher capability of driving load.
Humanized safety design, using isolation transformer design, input and output are completely electrically isolated, input and output are equipped with circuit breakers, which saving costs for the user and easy to installation, the electric parts are completely closed to prevent electric shock.
Wide input voltage can be set according to customer’s requirement. Input voltage range can be selected from 100-300V, 200-500V or 500-850V, suitable for solar system without backup batteries, it can save many cost and maximization use the solar system.
Using SVPWM space vector algorithms, high conversion efficiency, high instantaneous power and low losses conversion efficiency up to 94%.
Powerful data display function. LCD + LED display, can display input and output voltage, current, KWH, fault display, convenient for customers to quickly find faults and guide maintenance.
European CE (EMC, LVD, UL1741) and ISO9001 certificates.
