    LETON HV BEC 2.5A
Name:LETON HV BEC 2.5A
Listed Date:2007/2/25
Price: AUD$28.50
Sale: AUD$12.26


A new product,HV BEC 2.5A was released by Leton Technology Company to meet the demand of the customers which has the best cost performance. 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.

Just like other series of LETON’s product, HV BEC 2.5A is made under strict quality control standards. We promise that all our products are manufactured with high quality components.



Features:
● DC to DC switch-mode BEC of high frequency PWM technology, it’s great for compact and high efficiency.
● It can choose 5V output voltage or 6V output voltage to suit different kinds of servos
● Reverse Input Voltage Protection. Prevent BEC from damage when reverse polarity of the battery
● Over Input voltage protection
● Over current protection
● Over load and heat protection

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.

Specification:
Input Voltage: 4.4V (min) ~ 36V (max)
Battery Range:
LI-XX = 2 – 8cells; 7.2V – 33.6V
NI-XX = 4 – 26cells; 4.8V– 36V
BEC Current:2.5A
Output Voltage:5V or 6V (Select by a jump connector)
Protection:
* RVP Reverse Input Voltage Protection Prevent BEC from damage when
reverse polarity of the battery
* OVP, Over Voltage (battery) Protection
* OCP Over output current protection
* OLP Over load and heat protection
Working Ambient :0℃- 50℃
Weight: 5 g (without wires)
8g (including wires)
Dimensions: 35 x 21 x 5.5(mm) (size of board)

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.
