Product overview
The Rctimer 3A UBEC with Low Voltage Buzzer is a power-regulation component with a low-voltage audible warning feature. Its electrical configuration combines a 6.2 to 23V input range, identified with 2S ~ 5S LiPo batteries, and optional outputs of 5.1V or 6.2V. The current specification is 3A, with a stated maximum of 4A. Physically, the unit includes wiring, and its quoted 13.6g weight includes those wires.
Electrical integration must account for both the output-voltage option and the ripple figures under their stated conditions. Output ripple is 200mV peak to peak with a 0.5 to 1.5 Amp load and a 12V input. A separate figure increases ripple to 300 mV at a 24 Volt input. That latter measurement condition exceeds the specified 23V input ceiling, so it should not be interpreted as an extension of the operating input range.
