About This Product

DIASINE® is a DC-AC sine wave inverter that converts DC voltage to AC sine wave voltage. The output waveform is the same sine wave as the commercial power supply, and the distortion rate is less than 3%. Our research and development staff reconsidered the circuitry and structure from scratch to create a new design that is compact and fanless. High efficiency circuit and switching control achieve efficiency at rated load of 90% (GD150) / 89% (GD300) / 88% (GR300). This reduces the size of the product, does not include a built-in fan, and uses natural convection for cooling, resulting in extremely quiet operation. It also has a wealth of protection functions. Our unique input reverse connection polarity protection circuit will not damage the inverter's internal circuitry even if the input polarity is reversed. It has a wide input voltage range and operating temperature range, and can be turned on and off remotely, so it can be used in a variety of environments and applications. The redundant model GR300 series is a sine wave DC-AC inverter that converts DC voltage to AC sine wave voltage, and whose output can be connected in parallel to up to 6 units. By connecting the GR300 series in parallel, the output can be expanded to a maximum of 300VA x 6 units = 1,800VA. Our original synchronous control allows parallel output by simply connecting the output terminals. Installation and operation are now simpler, as there is no longer a need for a dedicated parallel control board or synchronization signal settings as with conventional products. Additionally, with N+1 redundancy, capacity can be easily expanded even after system installation. A protection circuit works for each unit, so even if one unit breaks down during operation, output can continue. Contributes to improving system stability and reliability. Rated output: 300VA, parallel operation possible

■Up to 6 units, fanless parallel output up to 1.8kVA

Up to 6 units can be connected in parallel without a fan, and the output capacity can be expanded to 1.8kVA.

■Parallel operation is achieved using only AC output wiring using unique synchronization technology

Our unique synchronous control technology (patent registered) enables parallel operation using only AC output wiring. Installation and operation are now simpler, as there is no longer a need for a dedicated parallel control board or synchronization signal settings as with conventional products.
