理士蓄电池DJM12200S UPS输出保护功能：

(1)输出短路保护:输出负载短略时，UPS应立即自动关闭输出，同时发出声光告警。

(6)抗雷击浪涌能力:UPS应具有防雷装置，能承受模拟雷击电压波形10/700us，幅值为5kV的冲击5次，模拟雷击电流波形8/20us，幅值为20kA的冲击5次，每次冲击间隔为1min，设备仍能正常工作，防雷装置具有保护功能。残压不高于1500V。

(1) Output short-circuit protection: When the output load is short, the UPS automatically shuts down the output and generates an audible and visual alarm.

(2) Output overload protection; When the output load exceeds the rated UPS load, an audible and visual alarm is generated. When the overload capacity is exceeded, the power supply should be transferred to bypass mode.

(3) Over-humidity protection: When the humidity inside the UPS is too high, the UPS generates an audible and visual alarm and automatically switches to bypass power supply. (4 Battery low voltage protection: When the UPS works in inverter mode, an audible and visual alarm is generated when the battery voltage reaches the protection point, and the power supply stops.

(5) Output overvoltage and undervoltage protection: When the UPS output voltage exceeds the preset value, an audible and visual alarm is generated and the UPS switches to bypass mode

(6) Lightning surge resistance: THE UPS should have lightning protection device, which can withstand the simulated lightning strike voltage waveform 10/700us, the amplitude of 5kV impact 5 times, simulated lightning current waveform 8/20us, the amplitude of 20kA impact 5 times, each impact interval is 1min, the equipment can still work normally, the lightning protection device has the protection function. Residual pressure is not higher than 1500V.
