Feature:
LCD input and output voltage, output current output power;
Input anti-reverse protection, reverse connection will not burn;
Can be step-up and step-down, the output voltage 0.5-30V arbitrary regulation, limiting the current 0-4A arbitrary regulation;
Output anti-intrusion, the battery charge without additional anti-reflux diodes;
Button control output ON / OFF status, and you can set the power-on default is ON or OFF;
Ascending and descending chip used as the main controller, external 60V 75A MOS tube as a switch, double 60V 5A SS56 Schottky rectification, 60V voltage value, superior to the market immature XL6009 / LM2577 program (a lot Device pressure value is not enough, MOS tube and Schottky diode pressure value must be greater than the input plus input voltage value);
Output ripple small, LC filter;
With heat sink, send module support isolation column.
Specifications:
... reverse protection: Yes
Output anti-intrusion: Yes
Short circuit protection: yes
Working frequency: 180KHZ
Size: 6.6*4.8cm/2.6*1.89inch
Note: This module is more than 3A, 35W use, please strengthen the heat! ! !
Note:
Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid
Due to the difference between different monitors
