? AC adjustable moving load box Overview: The load box is mainly used for electric power, telecommunications and other sectors and manufacturers of power-line UPS (uninterruptible power supply) and performance test generator sets, aging and other occasions. It is a device with a carrying capacity of important practical testing and maintenance of equipment. Its application effectively avoid economic loss reserve units or enterprises failed to start due to the power, but also provide a scientific basis for the new unit with a carrying capacity of detection and acceptance of the new battery. ? AC adjustable load-moving selection box Ordering Information: 1, special specifications can be customized according to customer requirements (optional AC single-phase, three-phase AC, fixed or adjustable resistance, resistive load, inductive load, high and low, IF load, non inductive load). 2, AC adjustable moving load boxes of non-standard custom-made, please provide the following parameters before ordering: ① Rated voltage (three-phase AC 0-400V / 230V, single-phase AC 0-600V, etc.); ② frequency parameter (. 50HZ / 60HZ / 400HZ, etc.); ③ Rated power KW / rated current A;. ④ power requirements of the minimum step / current minimum step requirements;.. ⑤ environmental conditions, operating mode (the default is long-term work system). ?
