The Mauch PL 4-6S multi-output BEC powers a drone's diverse electronics. It provides two independent 5.3V, 3A outputs for flight controllers and a dedicated 12V, 3A output for FPV gear or cameras, all from a 4S to 6S LiPo battery.
It is encased in a robust CFK (carbon fibre composite) enclosure, which the listing says gives clean, stable and protected power for demanding UAVs.
The design is a switching BEC (SMPS) with high efficiency, typically over 90%, and short-circuit and over-current protection for each output.
Two independent 5.3V outputs: 3A each, for flight controllers.
Dedicated 12V output: 3A, for FPV gear or cameras.
4S to 6S LiPo input: about 14.8V to 25.2V.
CFK enclosure: durable carbon fibre composite.
Reduced noise: less electrical noise and interference.
Compact and light: 19g without enclosure, 24g with it.
Per-output protection: short-circuit and over-current.
A BEC or UBEC (battery eliminator circuit) converts the high voltage of a flight battery to a lower, steady voltage for receivers, servos, flight controllers and other electronics. A switching regulator does this efficiently and gives off little heat, which is why it is preferred over a simple linear regulator when the input voltage is high.
When you choose a BEC, check that its input range covers your battery, that the output voltage suits your devices and that its continuous current rating is comfortably above what they draw. Servos and video transmitters can draw short bursts, so leave some headroom.
A clean supply also matters for radio equipment: a regulator with low ripple and low radio-frequency noise is less likely to interfere with a receiver or video link. Mount it away from antennas and keep the input and output wires short and twisted where you can.

The specification list gives an input of 4S to 6S LiPo (about 14.8V to 25.2V), outputs of two independent 5.3V (3A each) and one 12V (3A), a switching (SMPS) type and high efficiency (typically over 90%). Dimensions are 32 x 50 x 7mm and 19g without the enclosure, and 34 x 52 x 10mm and 24g with the enclosure.
The outputs use standard servo-style connectors and the battery input uses bare wires. The package includes a sensor cable, a Pixhawk 2.1 backup cable and a 12V output cable.
