The high-voltage AC/DC universal load bank is mainly used for load capacity testing, aging and discharge detection of AC equipment and DC equipment. It can be used for both AC and DC, and can be connected to AC or DC loads respectively, which can detect the backup battery of UPS and the load capacity of UPS AC output. The product is manufactured using the company's patented technology with independent intellectual property rights. The power element adopts a new power consumption component with high power density, stable resistance characteristics, flat resistance-temperature characteristics, and easy control.
