NOVELTY

EAN: 8595188188838 | Code: 8883

DESCRIPTION

It is used for monitoring voltage, phase failure, sequence, and asymmetry in the 3-phase network.
Wide range of monitored voltage with automatic selection of a low/ high range.
Fixed overvoltage level (Umax), adjustable Undervoltage level (Umin).
Adjustable time delay t2 (to eliminate short-term voltage drops and peaks).
Adjustable time delay t3 (to eliminate short-term OK state).
Adjustable asymmetry level with the option to turn it OFF.
Measures true root mean square value of the voltage - TRUE RMS.
Fault memory reset can be done by RESET button on the panel or by an external opening contact.
