Solar Power Inverter
35kw ultra-slim low frequency inverter
The ultra-slim low-frequency inverter is a “slimmed-down” version of the traditional low frequency inverter. It retains the low-frequency transformer isolation design, delivers a pure sine wave output, and offers strong overload capacity, capable of withstanding the startup surges of inductive loads such as motors and compressors. At the same time, by optimizing the core materials and heat dissipation structure, it is well-suited for vehicle emergency power, marine, and medical power supply applications.
- Using the sixth generation efficient IPM intelligentmodule from Japanese Mitsubishi, high efficiency and stable performance. It with powerful protection function, the protection for short circuit, over load, over temperature is more safe and reliable. It’s service life can up to 15 years or more.
- Intelligentized, modularized, simple structure design with powerful function.
- Two kinds of start mode: Step-downVoltage 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 frequency can be setting via LCD panel,it’s very convenient for customer.
- 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 settingvia the LCD panel.
- Pure sine wave output. With good dynamicresponse less than 50MS, waveform distortion rate smaller, higher conversion efficiency and stable output voltage.
- Low Frequency Transformer, which ensures that inverter has high efficiency.
- High conversion efficiency, Max. Efficiency≥97%
- Adopts black pure aluminum radiator, which confirms the best radiating performance.
- Powerful data display function. LCD can display the DC input voltage, output frequency, phase voltage, phase current, AC bypass input voltage, output power KWH, time and date, temperature, fault code display.
- Wide input voltage can be set according to customer’s requirement. Input voltage range can be selected from 100-400V or 300-800V
