|High Power BECs||Features:
5 volts - 2, 3, 5 and 7,5 Amperes - double receiver connectors
|Power supply replaces 4-cell Nicd packs for your receiver power supply|
Already widely used in Germany, now availabe for worldwide shipping !
|This high power BEC is an
ideal power supply for electric models with high servo activity, i.e.
electric helicopters, aerobatic models ...
BEC means "Battery Elimination Circuit", a circuit that makes a separate receiver battery unnecessary.
BEC's are widly used in electric models where a separate receiver pack cannot be used due to space or weight. The BEC gets its power from the motor battery and converts it into a voltage suitable for receiver, servos, gyros and more.
|A BEC circuit is already included in some motor controllers.
But this integrated BEC handles only up to about 1,5 amperes and usually
generates heat problems at high loads. It is not recommended for areas
with higher temperatures, in Summer or under closed canopies.
A good example is the ECO-8 helicopter. It's receiver, gyro and mainly four servos need often more power than integrated BECs could deliver without overheating.
|The solution is this external High-Power-BEC. It handles 5 volts at 2, 3, 5 or 7,5 Amperes and is therefore ideally suited for receiver system with high current consumption. It works with input voltages from 7 to 20 volts and has lots of reserve if the motor pack gets empty. Cooling requirements depend on the number of NiCd cells and current. Usually it can be used with up to 12 cells without external cooler because the high output current is drawn only during short periods of time. For higher power consumption or mounting inside the model a cooler is included in the standard BEC package.|
This BEC product line offers four types of low-noise precision linear voltage regulators. Depending on the model a low-budget 2A type or up to a powerful 7,5 A type may be used. The BECs have expensive low-drop regulators implemented which give good reserves if the model's battery gets empty.
All BECs have various security circuits and a diode against wrong polarity of the battery.
Usual BECs can forward HF distortions from the motor to the receiver resulting in poor quality of the received R/C signal. This BECs have a special dual-core filter included which supresses noise from the engine by up to factor 1000. This improves the stability of the R/C system dramatically compared to conventional BECs. The additional BEC filter (which is also offered by FlyHELI) is not required for these BECs. This filter is recommended for BECs from other manufacturers.
Which BEC for which moden ?
Four BEC types are available. They can deliver a maximum current of 2, 3, 5 or 7,5 Amperes. Choose the BEC according this table:
