Time Delay Undervoltage The IntelliVAC can be configured to provide time delay undervoltage
(TDUV) protection. The feature is available to keep electrically held
contactors closed during a voltage dip or brief power loss. This
option may require the addition of a capacitor (see Table 5.D). Refer
to Table 5.E for typical capacitor sizing. The capacitor is connected
to terminals 1(-) and 2(+) of the IntelliVAC. (Refer to Figure 5.8)

If the TDUV feature is used, the contactor
will not open until the programmed TDUV
time has expired. Therefore, applications
requiring an immediate removal of power
during emergency stop conditions are not
compatible with the TDUV feature.
Table 8.E of the “Configuration/Programming” Chapter 8 has the
DIP switch settings to provide TDUV from 0.2 to 2 seconds.
IntelliVAC can provide TDUV protection without the use of an
external capacitor, as shown in Table 5.D.
