BEC UBEC Brushless BEC 3A 5V Support 2-5S lipo battery
Features:
Switching design, the frequence of main control chip is 300KHz, both over-current and over-temperature protection, control chip efficiency is up to 92%;
2.2 small volume, light weight;
2.3 Electronic conponent is protected by shield, with magnetic ring, reduces electromagnetic interference effectively.
Specifications
Output capacity: 5V / 3A
Power Input: 5.5-21V (2-5S lithium batteries)
Size: 26 * 12 * 11mm (L * W * H)
Weight: 5g
Ripple way: less than 50mVp-p (2A/12V)
Advantage of switch BEC comparing with normal linear regulator BEC:
Heat emission is reduced effectively, increase efficiency
Take example 4S lipo battery,
1) Output current 5V/1A of normal BEC need 1A input current, power dissipation is 14.8x1=14.8w, while its current about 0.38A will be enough, the power dissipation is about 14.8x0.38=5.6w
