Parallel connection for power expansion up to 6 units (1.8kVA) without fan
DIASINE® GR300 series can be connected in parallel up to 6 units and the output power can be expanded to 1.8kVA without fan.
Synchronous control by AC output terminal
DENRYO’s original synchronous control technology (patented) enables GR300 work in parallel only have to connect AC output. This technology makes installation and operation become easier, because there is no need exclusive parallel control boards or complex synchronization signal setting like conventional products.
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.
N+1 redundancy
Because of the N+1 redundancy, GR300 makes the system expanded easier at any time. The function can also prevent the system stopping if a single unit failure. This contributes to improved system stability and reliability.
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 temperature range
DIASINE® operates reliably in a wide temperature range* of -20 to +60°C, making it suitable for use in harsh environments.
*Depending on the model, reduced load operation may be required. Please refer to the derating curves for details.
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 88% 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 — 100/110/115/120Vac for 100V models and 200/220/230/240Vac for 200V models — and the frequency (50/60Hz) can be easily switched using buttons. DIASINE® adapts to different regional voltage and frequency requirements, as well as to various types of electrical appliances.
