[0002] High-frequency switching power supply (also called switching rectifier SMR) is a power supply that works at high frequency through MOSFET or IGBT. The switching frequency is generally controlled within the range of 50-100kHz to achieve high efficiency and miniaturization; outdoor cabinet refers to a cabinet that is directly under the influence of natural climate, made of metal or non-metal materials, and does not allow unauthorized operators to enter and operate. It provides an outdoor physical working environment and safety system for wireless communication sites or wired network site workstations. It is suitable for cabinets installed in outdoor environments, such as highways, parks, rooftops, mountainous areas, and flat ground. Base station equipment, power equipment, batteries, temperature control equipment, transmission equipment and other supporting equipment can be installed in the cabinet, or installation space and heat exchange capacity can be reserved for the above equipment. It can provide reliable mechanical and environmental protection for the normal operation of internal equipment.
