With the Blue Gate Pure Sine Wave Line Interactive UPS series, you get not just the power backup your equipment needs for uninterrupted operation, but also full AVR function. Automatic voltage regulation is not only protective, but also means extended power availability. The AVR effect stabilises power that would otherwise be unsuitable for equipment to function, meaning you can now use them far more. The Blue Gate 4000VA line interactive UPS, BG4000, also delivers pure sine wave output. The pure sine wave output waveform of the Blue Gate means your equipment get clean pure sine wave power which is best for your sensitive, high-value equipment. The Blue Gate 4000VA Pure Sine Wave Line Interactive UPS (BG4000) will meet your UPS requirement for PCs, Workstations, Office Equipment, Home Appliances, POS Machines, and other similar devices. This Blue Gate UPS series has wide input voltage range of 165V – 280V which means extended availability of supply, as the UPS is able to stabilise the power fluctuations within that range.
