The Kyle Form 5 recloser control can be equipped with a
dc-to-dc converter, interface circuit, and a fully shielded
19-pin cable for use with a Type DC NOVA recloser. See
Figure 23.
The dc-to-dc converter board (Figure 24) converts the con-
trol’s 24 Vdc battery supply voltage to 53 Vdc to drive the
trip/close capacitors in the NOVA mechanism. The output
of the board is separately fused for operator indication.
The dc-to-dc converter houses voltage monitoring and
conditioning circuits which protect the battery from failure
and provides trip/close operations without AC power. The
19-pin control cable interfaces the NOVA dc recloser to
the Form 5 control through the interface circuit. The cable
also provides AC power from the control to the recloser
mechanism heater.
