1503VC-BMC4 | Intellivac Contactor Control Module

• A range of supply voltage (110 – 240V AC 50/60 Hz, 110 – 250V DC) allows implementation in multiple applications.
• Consistent vacuum contactor pick-up time (at a given supply voltage) ensures repeatable performance.
• Selectable vacuum contactor drop-out time improves coordination with upstream power fuses.
• Electronic altitude compensation (Bulletin 1502 400 A only) eliminates mechanical compensation required for altitudes above 1000 meters (Bulletin 1502 800 A contactors include a user-friendly mechanical altitude adjustment).
• Power loss ride-through (TDUV) allows the vacuum contactor to remain closed during short power loss (may require an optional external capacitor, dependent on ride-through time).
• Anti-kiss and anti-pumping protection ensure that the vacuum contactor close – open sequence occurs as expected, avoiding rapid reclosure due to faulty control devices.
• Delayed restart protects the vacuum contactor by ensuring that the rated duty cycle is not exceeded.
• Temporary jog function (electrically held contactors only) allows the motor to be positioned for process set-up.
