Undervoltage Monitor with Reset

The Undervoltage Monitor With Reset (acknowledgment) has outputs for a signal, buzzer or other indicators. It can be used to turn on/off acoustic or optical warning signals when the input voltage drops below/exceeds a defined voltage level. When the input volt­age ap­plied to ter­mi­nal 15 drops below the de­fined thresh­old volt­age out­puts 87, 87a, and C are turned on. Out­put 87 can be switched off again via reset input x (ac­knowl­edge­ment) while out­puts 87a and C re­main on. When the input volt­age on ter­mi­nal 15 ex­ceeds the de­fined thresh­old volt­age all out­puts are switched off. Cus­tom thresh­old volt­ages are avail­able on re­quest. Please refer to the chap­ter hous­ing and base plates for ad­di­tional hous­ing op­tions.
