High Wattage Alloy Plate Type Resistance Cabinet High Capacity Load Balance Resistive Testing Machine
Introduction
The high-power resistance cabinet is used in high-power inverter power supplies, high-power adjustable DC power supplies, high-power frequency conversion power supplies and high-power DC motors, which are all high-power electrical equipment. To balance the load and prevent overcurrent, and to protect the equipment safety, it is assembled by designing modular high-power alloy plate-type resistance cabinets. The product is widely applied in fields such as ships, power, ports, telecommunications, petroleum, metallurgy, nuclear power, and marine engineering.
It is manufactured by using high-quality load resistors independently developed by Lonroy and new alloy resistors. According to the requirements of the energy dissipation resistor cabinet and the current-limiting resistor cabinet, the heat dissipation structure and protection level have been optimized. It has the functions of adjustment and remote control, and can be selected. The large screen displays the data. It can be used for the loading test of high-power power supplies and the energy dissipation needs of high-voltage generator electromotive force resistor cabinets. This product has the advantages of large current, high control accuracy and good heat dissipation performance.
