trip power. The CTDA-6 converts ac buss voltage to dc voltage and stores enough energy to operate a lock out relay or trip a circuit breaker. Voltage is
available from the ac power supply for tripping immediately upon ac power up. The capacitors charge time is approximately 8 seconds, but full wave bridge
rectif ier power from the ac line is available immediately for use. Capacitor charge current is limited to protect the control power system from a large current in
rush. This feature allows the use of many CTDA-6 units from the same control power voltage source without coordination problems. Additionally, the CTDA-6 is
self-protected from short circuit damage on the output . Nominal ac voltage is applied across terminals #8 and # 10. This voltage is full wave bridge rectif ied
and applied across the trip capacitors producing a steady state output trip voltage. The charge stored in theses capacitors is available across terminals #12
(positive) and # 14 (negative).Charging time: 8 seconds, 0 to 90% of nominal output voltage, 60 hertz. Operating temperature: -30 deg C to +60 deg C
Electrical specif ications are 25 deg C.
Notice: Ac power must be applied continually for minimum of 2 hours before the CTDA-6 is capable of developing full charge on the output capacitors
with sustained interruption in ac input . The CTDA-6 capacitor trip device is not intended for ac dc power supply. The self-protecting feature of the unit
will severely limit the continuous output current and voltage.
Servicing:
1. Remove the AC control voltage.
2. Discharge the Capacitor trip device.
(A5-watt resistor of approximately 1000
ohms across Terminal #12 and #14
can be used for this purpose).
Danger!
Lethal voltages are present qualif ied
persons should install, operate, and
service this device.
