The AC/DC circulating load device "Loop Square" is a testing device for power supply circuits that integrates the power supply and load by returning the output power of the tested equipment back to the input, thus serving as the driving power for the tested equipment itself. The power consumption of the circulating load device is only enough to compensate for the internal losses of the tested equipment and the load device itself, allowing most of the driving power to utilize the output power of the tested equipment. This enables large-capacity electrical devices to operate with minimal power consumption. 【Features】 - Compact size that fits on a table - Weighs only 14 kg, making it easy to carry - Powered by 100V, simply plug it into an outlet - Comes with a carrying case - Easy to rearrange laboratory layouts, etc. *For more details, please download the PDF or feel free to contact us.
