Multifunction voltage monitoring relays AC/DC - PMR1-31

DESCRIPTION

• It is used to monitor the value of alternating or direct voltage in 1-phase circuits.
• Supply voltage from monitored voltage.
• Monitors voltage exceeding the upper voltage level (Umax) and falling below the lower voltage level (Umin) – according to the selected function.
• Smooth adjustment of both voltage levels – the lower level Umin is set in % of the upper-level Umax.
• Adjustable time delay (to eliminate short-term voltage drops and peaks).
• Option to select functions with fault state memory (Latch).
• The fault state memory can be reset with a button on the panel (RESET).
• Measures true root mean square value of the voltage - TRUE RMS.
