It’s a combination of the magnetic switch and a 7 amp voltage regulator. Available in 2 output voltages: 5.7 & 7.4V Introduction As with our other products, the Zepsus Magnetic BEC “linear voltage regulator” was designed with one thing in mind, not compromising on quality. With that said, the best components have been selected. No cheap solutions, this is the best of the best all the way around from engineering to production. It outperforms many of its competitors with large 200µF, high quality low ESR filter capacitors. On-off indication utilizes a super bright LED, even visible through some fuselages. A clean and easy way to turn on your model, just slide the magnet across the BEC. Mounted inside of 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 The Magnetic BEC has the same well-known and well-tested magnetic technology as the Zepsus Magnetic Switches. If a servo burns out in flight, the very high peak current will help the Magnetic BEC provide power to continue the flight and burn the servo electronics. Other BEC's would burn out, resulting in a crashed plane. No buck or boost converters. No charge pumps. No switching noise. This makes the Zepsus Magnetic BEC an ultra low noise product suitable for radio controlled gliders where long range is very important. Ultra low dropout voltage provides security if a battery cell collapses and the input voltage suddenly drops below the selected output voltage. 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 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 BEC's have been tested with more than a 30A burst followed by 7A for 5 sec before delivery. Standby current is adjusted and a visual inspection is made. All tests are done with an 8V supply.
