Kyle Form 5, Form 5 UDP, Form 5 DC NOVA Recloser Control Installation and Operation Instructions
FORM 5 DC NOVA CONTROL
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 control ’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.
