Multifunction voltage monitoring relays AC/DC - PMR1-39

NOVELTY

EAN: 8595188188685 | Code: 8868

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.
