Zepsus Magnetic Switch

Due to popular demand, SoaringUSA has brought to you the newest in Magnetic Switch technology with BEC!

Zepsus Magnetic BEC “linear voltage regulator” was designed with one thing in mind: no compromise in quality. The best components have been selected. No cheap solutions, this is the best of the best all the way around. It outperforms many of its competitors with massive 200µF high quality low ESR stabilization capacitors. On-off indication is a super bright LED, visible through some fuselages! A clean and easy way to turn on your model, just slide the magnet across the BEC.
It is mounted inside the fuselage, out of the air stream, and the magnet will easily activate the BEC from outside. No more fumbling for little switches, or plugging in connectors.

Four reasons to buy the Zepsus Magnetic BEC:
1.) The Magnetic BEC has the same well-known and well-tested magnetic technology as the Zepsus Magnetic Switches.
2.) If a servo burns out in flight, the extreme high peak current will help the Magnetic BEC provide power to continue the flight and burn the servo electronics. Other BEC will give up, resulting is a crashed plane.
3.) No buck or boost converter. No charge pump. No switching noise. This makes the Zepsus Magnetic BEC a ultra low noise product suitable for radio controlled gliders where a long range is very important.
4.) Ultra low dropout voltage provides security if a battery cell collapses and input voltage suddenly drops below selected output voltage.

*Depending on Input and Output voltage.
**If input voltage drops below output voltage.
Test at +20C ambient temperature

Calculation example of continuous current:
Max power loss continuously / (Input voltage – Output voltage) = current continuously
2S Lipo nominal voltage 7.4V and output voltage is 5.7V.
3 / (7.4 – 5.7) = 1.76A
2S Lipo nominal voltage 7.4V and output voltage is 6.5V.
3 / (7.4 – 6.5) = 3.33A
2S Lipo nominal voltage 7.4V and output voltage is 7.4V.
As long as the Input V is lower or the same as the Output V, the continuous current is 7A
Production test All BECs have been tested with more than a 30A burst followed by 7A for 5 sec before delivery. Standby consumption is controlled and a visual inspection is made. All tests done with 8V input.
