1) over-voltage/low-voltage
过压/欠压
2) overvoltage-undervoltage
过欠压
1.
Based on the special qualifications in switching power supply for microcomputer relay protection and the power supply which has been developed,firstly the scheme of main circuit is introduced,then the realization of outputs overvoltage-undervoltage protection is discussed.
针对微机继电保护用开关电源的特殊技术指标,结合所开发的继电保护用开关电源(以下简称继保电源),介绍了主电路设计方案,讨论了电源输出过欠压保护的实现方式,比较了5V与24 V启动关机时序配合的2种电路,从理论上分析了电源异常保护后不可自恢复的实现手段。
3) over or under bias-voltage mode
过、欠电压型
4) Over & Under Voltage Safeguard
过欠压保护
5) undervoltage/overvoltage monitor
欠压/过压监测器
1.
The MAX6459 is a new type high-voltage,low-current undervoltage/overvoltage monitor.
HAX6459是一种新型高压、低电流欠压/过压监测器。
6) overvoltage or undervoltage protector
过压欠压保护器
1.
Because of its sensitivity to voltage of power network, an overvoltage or undervoltage protector will cut off the power of electrical appliance to protect it from being destroyed by abnormal voltage.
应用敏感于电网电压的基本特性,过压欠压保护器及时将用电器的电源切断,以保护用电器免受非常规电压的破坏。
