Castle Creations - Battery Eliminator Circuit




	Part Number CCR0400 Current Output: 10 ams Continuous: >12 volts input = 7 amps* >24 volts input = 5amps* *Ratings are determined with a 5mph airflow on the BEC. Servo connectors are not rated for current in excess of 5 amps. Users are encouraged to replace the connectors if more than 5 amp currents are anticipated. Output Voltage: Output 5.1 volts out of the package, user may set output voltage from 4.8 to 9 using the Castle Link (sold separately). Input Voltage: 5v to 25.2v (2S to 6S LiPo) Length: 30mm (1.2”) Width: 15mm (0.6”) Height: 10mm (0.4”) Weight: 11 grams (0.4 oz)

CC Battery Eliminator Circuit (BEC)
Up to 6S max input

The Castle Creations (CC) battery eliminator circuit is a superb little electronic device that eliminates the need to use a separate receiver and servo battery pack in your model. It draws slightly higher voltage from the motor batteries and reduces it to a voltage level that is suitable to power your receiver and servos. This is ideal for use in installations that draw high power for multiple servos, or use more than 3S Li-Po battery motor packs, as most electronic speed controllers (ESCs) with linear BECs are not designed for these applications. Designed with the electric flyer in mind the Castle Creations BEC offers, compactness, economy and more power.

The CC BEC™ is designed to offer up to 10 amps peak current for 30 seconds, up to 7 amps continuous current at inputs under 12 volts, and 5 amps continuous current with inputs under 25 volts. That’s plenty of power for almost any number of servos and the possibilities of employing this product anywhere a stable voltage is required from a battery source are endless. Ever wanted to run the newer servos that are capable of 8 or 9 volt inputs, well now you can. If you fly 3D / Pattern you’ll love the ability to tune servos voltage to increase control power and response of your plane.

CC BEC PRO
Up to 12S max input

CC BEC PRO is a high output switching BEC (battery eliminator circuit). BECs
replace the receiver battery pack in many applications and they draw their
power from the same pack that drives the motor in the vehicle. This pack is
generally a much higher voltage than the RX and servos need, so this device
is needed to drop the voltage to a level that is safe for the RX & Servos.

The CC BEC PRO is rated for up to 12S input (50.4 volts), has a peak output
of up to 20 amps and is intended for use in larger electric aircraft and helis that
have high power demands for their radio / servo system. It is ideal for most electric
helis 500 size and larger. It will also work well in larger electric powered RC
aircraft that have high powered servos.

Problem prevention with BEC’s

CC BEC Usage Advisory #1

Problem
Damaged CC BECs may NOT reduce voltage from input levels and radio equipment exposed to the higher voltage may be damaged.

Recommendation
Never use a CC BEC that has experienced crash forces or that may have been in a system experiencing an electrical failure in another component in
the system without first checking the output with a volt meter or returning it to Castle for evaluation.

Explanation
The CC BEC is designed to step voltage down from a high level to a lower level. If the CC BEC is damaged by crash or misuse it is possible that it will NOT
step the voltage down. Always use a voltmeter to check the operation of the CC BEC after a crash or known electrical system failure.

CC BEC Usage Advisory #2
NOTE: This is NOT applicable to CC BEC Pro.
CC BEC/SPEKTRUM Compatibility instructions

Castle has learned of a slight incompatibility of the CC BEC with the SPEKTRUM AR 6100, 6200, 7000, JR 790 ScanSelect, and JR 2100 ScanSelect Synthesized
receivers. There is a very easy work around for our customers who already have the CC BEC and we are making modifications to the components of all
new CC BECs that are built from Nov. 1, 2007, forward.

The simple explanation is that the CC BEC, like most Castle products, is designed to be USB linkable via the signal wire on the servo connector. As part of that,
the CC BEC will pull the signal wire to ground unless it is sending a signal on that line. Nothing out of the ordinary with this. Similarly, the Spektrum team designed
these receivers to look for a grounded signal pin on the battery port in order to initiate binding. Nothing strange there either. Castle does something similar with
our Berg receivers. The problem is that the two designs result in the CC BEC triggering the receiver's binding mode immediately upon power up. We have
redesigned the CC BEC to facilitate the USB activities without initiating the binding mode.

For those of you with the affected CC BECs and Spektrum receivers there are at least three solutions:

1. Remove the orange signal wire from the CC BEC RX power lead before you plug the lead into the battery port on the receiver.
2. Plug the entire/intact lead from the CC BEC into any other port on the receiver.
3. Use a "Y" connector to plug the entire CC BEC lead into any port other than the BATT port on the receiver.

If you are unsatisfied with any of the above solutions, please simply send your CC BEC to Castle for upgrade.

Please note that this incompatibility will be immediately apparent. There are no known issues after the system is successfully powered up.
