IntelliVAC Features
ƒ A wide range of supply voltage (110 – 240 V AC 50/60 Hz,
110 - 250 V DC) allows implementation in multiple applications
ƒ Consistent vacuum contactor pick-up time (at a given supply
voltage) ensures repeatable performance
ƒ Selectable vacuum contactor drop-out time improves
coordination with upstream power fuses
ƒ Electronic altitude compensation (400 A only) eliminates
mechanical compensation required for altitudes above 1,000
meters (800 A contactors include a user-friendly altitude
adjustment)
ƒ Power loss ride-through (TDUV) allows the vacuum contactor
to remain closed during short power loss (may require an
optional external capacitor, dependant on ride-through time)
