HV BEC2.5A is a DC to DC switch-mode BEC, it can used in R/C plane power system which can step down the voltage of the battery and supply power for the receiver and servo and other electronic suppliers. The high frequency PWM power control technology was employed in HV BEC 2.5A; the maximum input voltage of HV BEC 2.5A is 36V which can supply 2.5A output current. HV BEC 2.5A is great for high efficiency and low heat generation, and it can choose 5V output voltage or 6V output voltage with a jump connector to suit different power supplies of the servo.

Advantages： DC to DC switch-mode BEC have high efficiency and low power dissipation, so that it has low heat generation.
Traditional regulator is linear voltage regulator; the output voltage of the BEC is steady, and the output current and the input current are the same, as a result, the higher input voltage of the BEC, the higher dissipation power and higher heat generation due to stepping down the voltage of the BEC. That’s the reason of the temperature of the BEC is higher when using four cells lithium battery than using two cells lithium battery.
For example, when the output voltage is 5V, the output current is 1A, so the output power is 5W, the input voltage is 10V, the input current is 1A；Therefore the dissipation power is (10V-5V) ×1A=5W. So the temperature of the BEC is very high.
Because of the application of high frequency switch control technology, the switch-mode regulation circuit can handle the input power down to 90 percent of output power.
For example, the output voltage is 5V, the output current is 1A, so the output power is 5W, the input power is about 5.5W, If the input voltage is 10V,the input current is 0.55A; if the input voltage is 30V, the input current is only 0.18A, therefore it costs steady only 0.5W
Therefore the switch-mode regulation circuit is great for high efficiency, low heat generation and low power dissipation.
