adj.降低電壓的 ; 欠電壓的
With the perfect protection functions in over voltage, under voltage, over heat, over current, over load, safe and reliable. 具有完善的過(guò)壓,欠壓,過(guò)熱,過(guò)流,過(guò)載自動(dòng)保護(hù)功能,安全可靠。
Internal circuit protection includes thermal shutdown with hysteresis, under voltage lockout, locked rotor and dead time protection. 內(nèi)部電路保護(hù)包括因滯后引起的過(guò)熱關(guān)機(jī)、欠壓鎖定、轉(zhuǎn)子鎖定以及停機(jī)時(shí)間保護(hù)。
While L1, L2 and L3 phases are over or under voltage, the yellow light is lighted with the unlighted green light and the released relay. L3三相過(guò)壓或欠壓時(shí),黃燈亮,綠燈不亮,繼電器釋放;
Under voltage protection: It means the voltage of the protected circuit is lower than set value. In this case, the yellow indicator light will be lighted. 欠壓保護(hù):指被保護(hù)線路電壓低于設(shè)定值。指示燈形式為:黃燈亮;
The Device has integrated over-current protection,over-temperature protection and UVLO (Under Voltage Lockout) to provide for a fail safe solution with no external components. 這個(gè)器件集成了過(guò)流保護(hù)、過(guò)溫保護(hù)和U掉壓關(guān)斷的功能，可以不需外轉(zhuǎn)器件實(shí)現(xiàn)保護(hù)解決方案。
This paper pays more attention to analyze the accidental conditions of the USB system, and the circuit can detect the overcurrent condition and realize the overcurrent protection, under voltage lockout and over temperature protection. 并針對(duì)usb系統(tǒng)工作時(shí)可能出現(xiàn)的意外情況 ,通過(guò)限流開(kāi)關(guān)內(nèi)部電路實(shí)現(xiàn)過(guò)流檢測(cè)、過(guò)流保護(hù)、欠壓鎖定和過(guò)熱保護(hù)功能。
