  • The smallest sine wave DC-AC power inverter in the world
    • DIASINE® has achieved the lightest weight of 0.9kg and the smallest volume of 1.5L in the same output class of inverters. The height of DIASINE® is 44mm/ 1.7 inch (1U). The lightweight and small features reduce the system weight and size.

  • Input reverse polarity connection protection by built-in circuit
    •  Existing inverters will be damaged if the input battery is connected in reverse. DIASINE® has the exclusively own built-in circuit of input reverse polarity protection. This circuit protects DIASINE® not to get damaged even if the battery is connected with reverse polarity. Moreover, the reverse polarity warning LED of DIASINE® lights immediately to inform the user the reverse polarity connection.

  • Operating silently based on fanless structure
    • The efficient heat design achieved the fanless structure. The fanless structure leads silently operation without the fan-generated noise.

  • Wide input voltage range
    • The input voltage range of DIASINE® is wider than other inverters in the same class. Therefore, batteries with wide range variation of voltage, such as lithium-ion batteries, can be used. It is also possible to charge battery while the DIASINE® is operating.

  • Wide range of operating temperature
    • DIASINE® operates under a wide range of temperature from -20 to 60°C.
    *DIASINE® GD300 will not stop the output automatically. Under the environment with temperature exceeding 40°C, please use the load along refer to the derating curve of each model.

  • Pure sine wave output and high efficiency
    •  The output waveform is as same as the sine wave of commercial power supply, of which the total harmonic distortion is less than 3%. High-efficiency circuit and switching control achieve over 89% efficiency at rated load. It contributes to the stability of the system during operation without extra wasted energy consumption.

  • Switchable output voltage and frequency
    • The output voltage 100/110/115/120 Vac (100V model), 200/220/230/240 Vac (200V model), and frequency 50/60 Hz easily switch by buttons. DIASINE® adapts to areas with different voltage, frequency, and various electric appliances.
