S&C IntelliCap 2000 User Manual

Connected to a potential transformer, the PT wires provide voltage sensing and power
to the control and internal relays. Average IntelliCap 2000 control power consumption is
0.5 watt. Control power is used to wett the open and close relay contacts to operate the
capacitor bank switches or the interposing relays.
The IntelliCap 2000 control relay contacts are rated at 20 A @ 250 Vac. In addition, they
have been tested to operate three Joslyn vacuum switches (36 A). If you need 125 Vdc to
operate the capacitor switches, install interposing relays rated for 125 Vdc.
Control power is used as wetting voltge for the Open and Close relays and is not fused
in the IntelliCap 2000 control. An external fuse must be installed when necessary. Polarity
and phase-angle corrections can be adjusted with the control software.
