provide circuit breaker trip power. The CTDB-6 converts ac bus voltage to dc voltage and stores enough energy to operate a lock out relay or trip a circuit
breaker , often more than once. The CTDB-6, when fully charged, will maintain a charge for a minimum of 3 days after the ac power has been interrupted. In
normal operation, the batteries are trickle charged from the ac voltage source. Voltage is available from the ac power supply for tripping immediately upon
ac voltage power up. Capacitors do not need to be charged to have tripping voltage available on the output of the device, this is because the output is
automatically fed from the full wave bridge rectif ied ac signal or the charged capacitors, which ever is greater. Capacitor charge current is limited to
protect the control power system from a large current in-rush. this feature allows the use of many CTDB-6 units from the same control power voltage
source without coordination problems. Additionally, the CTDB-6 is self-protected from short circuit damage on the output . Batteries: 4 - rechargeable 1.2
volt Ni-Cad Cells * Electrical specif ications are at 25 deg C
Notice: Ac power must be applied continually for minimum of 2 hours before the CTDB-6 is capable of developing full charge on the capacitors with a
sustained interruption in ac input . It is highly recommended that batteries be fully charged before installing into the CTDB-6. The CTDB-6 is designed to
trickle charge the batteries to hold a charge indef initely, but the CTDB-6 trickle charge circuit can take as long as 48 hours to charge batteries that are
completely discharged. The CTDB-6 capacitor trip device is not intended for use as a dc power supply. The self protecting feature of the unit will severely
limit the continuous output current and voltage.
The Automatic Charging Trip Device (CTDB-6) is used to trip circuit breakers and lock out relay when a battery or standby source is not available to
