Castle Creations CC-BEC RX Battery Eliminator Circuit

What the heck is a BEC? CC BEC Battery Eliminator Circuit is a little device that eliminates the need for a receiver and servo battery pack. It draws higher voltage from the motor batteries and drops it to a voltage level that is suitable for your receiver and servos. This is required in applications which draw high power for multiple servos or use more than 3S motor packs, as most ESCs with linear BECs are not designed for these applications. The CC BEC uses a Switch Rate method that is vastly more efficient than common circuits that sweat off much of your power through a heat sink.

Peak Current Output: 10 amps
Continuous Current Output: @12 Volts input 7amps, @ 24volts input 5 amps **
Output Voltage: 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: 5 to 25.2v (2S to 6S LiPo)
Length: 1.2" (30mm), Width: .6" (15mm), Height: 4" (10mm)
Weight: 0.4 oz (11 grams)

**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. Modifications available below. For models containing digital servos (3D Heli's for sure!) which could demand currents 4 amps or more, increasing the output connection with double leads is strongly urged.

Castle Creations CC-BEC PRO Battery Eliminator Circuit

Need a BEC to drive a really large load? Useful for high servo counts or many digital servos on larger craft. Use as a power supply aboard your UAV to drive sensor, transmitters or whatever your client has you testing.

NOTE: CC BEC Pro should never be operated in series or parallel with another BEC or backup receiver pack connected to the RX/Servo side of the circuit.

Size: 1.69" (43mm) x 1.3" (33mm)
Height: 0.94" (24mm)
Weight: 1 oz* (29g*)
Max Amps: 20 amps peak**
Max Volts: 2s to 6s LiPo Cars: 6s (25v), Airplanes: 10s (40v), Helicopters (with brake disabled): 12s (50v)
Adjustable Output Voltage :4.8V to 12.5V

*Weight without wires
**Ratings are determined with a 5mph airflow on the BEC.

Advice from Dave on setting voltage: For simulating a typical 4.8V RX pack set voltage 5.1 to 5.4. For simulating a 6V pack, set voltage to 6.4 to 6.8. Battery packs are not any set voltage but work over a range of voltages. Think about what your trying to simulate. A 4.8v pack is empty at about 4.4v, full at about 6v. A 6v pack is empty at 5.5 and full at about 7.5. For heli's where the tail servo and gyro won't take 6v packs, what the MFG is saying is it won't take 7.5V. Setting heli voltage to even 5.8 or 5.9 is fine as it just looks like a 4.8V pack hot off the charger. For older 2.4GHZ systems (Anything not Hitec/Airtronics and pre 2011 gear) we reccomend setting voltage to 5.4-6V range MINIMUM.

Maxx Products 5.4V / 6V 6 Volt Voltage Regulator

Protects equipment from over voltage. A 5 cell Rx NiCd battery pack (7.5 volts hot off charger) offers the advantage of faster servos with more torque. But, when fully charged this same pack can cause jittery servos. Also, many ignition systems need to see voltage from a 4 cell 4.8v pack (up to 6v hot off the charger). The ACC134N to regulates the higher input voltage down to either 5.4v or 6.0v (user adjustable). Thereby providing the right input voltage for your ignition or eliminating servo jitter. Universal connector set easily fits between JR, Futaba J, Hitec & Airtronics Z. In the event your source battery falls below 6V the regulator continues to pass voltage at reduced levels tracking the pack voltage down.

Specifications:
Output Voltage at circuit: Aproximately 5.4 or 6V
Current capacity: 5A continuous, 10A peak(@7.4V input)
Input Range: 4.8V to 8.4V

Castle Creations CC-BEC Lipo/Heli

Use between your RX and Gyro/Tail Servo. Allows use of higher voltage RX packs like 6V and 2 cell A123 packs to drive your head servos and RX while keeping your tail on a steady diet of 5.1V (default setting). Regulator is switch rate so no wasted energy through heat sinks like lessor regulators. Comes set to 5.1V but we can adjust to whatever setting you'd like, see drop down boxes.

Advice from Dave on setting voltage: For simulating a typical 4.8V RX pack set voltage 5.1 to 5.4. For simulating a 6V pack, set voltage to 6.4 to 6.8. Battery packs are not any set voltage but work over a range of voltages. Think about what your trying to simulate. A 4.8v pack is empty at about 4.4v, full at about 6v.

Dimension Engineering 25W Step Down Adjustable Switching Regulator

The Dimension Engineering DE-SWADJ 3 is a larger version of our DE-SWADJ adjustable step down voltage regulator. Previously it was necessary to put multiple DE-SWADJ units in parallel to achieve ratings over 1A, which was bulky, expensive and carried with it a considerable increase in dropout voltage. The DE-SWADJ 3 is designed to be stronger, faster and better. It can process 3A of current, typical ripple is 25mV and under ideal circumstances the regulator can be up to 96% efficient.
It continues the ease-of-use of the DE-SWADJ, making it simple to add an adjustable voltage source to a new or existing project with all the efficiency benefits of switch-mode power. The DE-SWADJ 3 is pin-compatible with the common 78XX family of linear voltage regulators, and has a small screw on top that allows you change the output voltage as your project evolves. It has integrated decoupling capacitors, so external capacitors are not generally necessary.
DE-SWADJ3 can deliver a maximum of 25 Watts.
The screw potentiometer on DE-SWADJ is worm-gear driven, so small vibrations and movement will not cause the voltage to shift. Use of glue to hold the screw in place is strongly discouraged and could damage the device.
Product Specs:
Model: DE-SWADJ3
Performance: Adjustable from 3 to 13V output using screw
3A output at 3 to 8V
(Please see datasheet for current ratings at higher voltages)
>90% efficiency
1.2V typical dropout voltage, 2.0v maximum at full load

Dimension Engineering AnyVolt Micro Universal DC-DC Switching Converter

AnyVolt Micro is a miniature step-up / step-down switching DC-DC converter. The output is adjustable from 2.6V to 14V and currents up to 0.5A can be drawn. AnyVolt Micro is useful when you need to step from a lower voltage to a higher voltage, or when your input voltage occasionally dips below the output voltage. The output voltage is set with a small screw potentiometer on the side of the AnyVolt Micro. Once the output voltage is set, it does not matter whether input voltage is higher, lower, or the same as the desired output i.e. there is no dropout voltage. The AnyVolt Micro is pin-compatible with the common 78XX series of linear voltage regulators, so it will work with breadboards and other popular prototyping methods. AnyVolt Micro is very different from any other DC-DC converter on the market so please read the entire datasheet thoroughly before buying or using one. AnyVolt Micro is the smaller, lighter and cheaper successor to AnyVolt Mini. It also adds thermal, overcurrent and short circuit protection, making it very hard to kill (like zombies). Never soldered before? You might like our breakout boards. Product Specs Model: AnyVolt Micro Performance: 2.6V to 14V output voltage range 2.6V to 14V input voltage range 0.5A max input or output current at < 10V (please see datasheet for current ratings at higher voltages) <50mV typical ripple No external components needed Protective features: Overcurrent protection Thermal (overheating) protection Shorted output protection Applications: Lab work and prototyping Powering 9V and 12V video transmitters Powering small audio amplifiers Driving multiple LEDs in series Backlit LCD drive Solar powered applications High power crystal based radio transmitters Battery powered applications Renewable energy source applications Universal battery charger Powering things from two AA batteries Powering things from a single lithium cell USB powered mayhem

Align Two-way Voltage Clipper

Align describes this products as a 5.1V regulator. It's functionality is more of a voltage clipper in that it takes about .25v off the top of whatever you pass through it. If you have a servo that is a bit jittery at the top of the battery pack charge, you can use this product inline to clip off .25v and it will likely solve your problem. This is not a regulator, it's a useful product for some applications but like many things from China, not exactly what they say it is. ;-)

Fromeco Super Sahara Regualtor

The all new Sahara Regulator by Fromeco is one of the highest rated Linear regulators in the RC market. Specifically designed to operate at High Delta V, pass high currents, and dissipate more heat than any of our competitors. The Sahara is capable of 9amps of continuous current. The new Sahara, is as light as the old retired "the Regulator" that used to be offered by Fromeco. Weighing in at 1.4oz's with 9"Deans and 2 JR out puts, and about 1.1oz with the "standard" JR in and out. The new increased current capacity that the Sahara can handle makes it an excellent choice for the new power hungry servos in todays market.

Fromeco Regulators are FULLY ADJUSTABLE, voltage is adjustable from 5.4VDC to 6.4VDC voltages may vary -+ .05 volts on upper and lower end.

Building off one of Fromeco's best, and most used Regulators in the market, the "Arizona" regulator line for helicopters. The Sahara is a vetted design, utilizing traces that are 3/32" wide. Combine those details with 16awg wire, Deans Connectors or Anderson Power Poles, **3 out put leads, and a massive heat sink, as standard equipment and you have a regulator like few others in the market.
