VME421H-D-2  BENDER  Voltage Monitor

INQUIRE NOW

Products Name: VME421H-D-2 BENDER

PRODUCT DESCRIPTION

Also in the event of complete power failure of the system being monitored, the delay times 

are effective during the energy backup time. When the fault memory is set to continuous 

mode, the alarm parameters remain stored, even on failure of the supply voltage.
