20A high -power synchronization rectifier low -voltage low -voltage constant voltage power supply module charging LED driver 300W high power

What is synchronous rectification:

Synchronous rectification is a new technology that uses a special power MOSFET with extremely low -state resistance to replace the rectifier diode to reduce the rectification loss.It can greatly improve the efficiency of the DC/DC converter and there is no dead zone voltage caused by the voltage of the Schottki barrier.

Features:

*6-40V wide voltage input

*Synchronous rectification 97%high efficiency

*Constitution and constant current output continuously adjustable

*Two 85V 80A large current MOS tube

*Use 23M iron silicon aluminum 3 0.8mm pure copper wires.

Module parameter;

Module Nature: Synchronous rectification non -isolation reduction constant flow constant pressure module

Input voltage: 6-40VDC

Output voltage: Continuously adjustable (1.2-35VDC) for 32V long time (applicable to applications with an input voltage higher than the output voltage cannot be increased))

Output current: The maximum 20A length is within 15A (the power tube temperature exceeds 65 degrees, please add a fan to dissipate heat, please use the amount of high voltage output, please use it))

Flowing range: 0.3.-20A (adjustment) module exceeds 65 degrees, please add a fan.

Minimum pressure difference: 3V

Working frequency: 150kHz

Conversion efficiency: About 97% of the efficiency is related to the pressure difference and the use environment

Output ripple: about 50mv (excluding noise) 20M bandwidth (for reference only) input 24V measurement

Work temperature: -10 ° C to +75 ° C) (Actual use, please pay attention to the power tube temperature. If the temperature is too high, please strengthen the heat dissipation or reduce the amount)

Potquime regulating direction: clockwise (increase), counterclockwise (decrease)

Output short -circuit protection: (instantaneous protection) constant current (currently setting up the constant current value cannot be short -circuited for a long time)

Enter anti -connection protection: none,

Output anti -anti -irrigation: none, for load self -charged or emotional load, you need to add a diode!

Wiring method: Wiring terminal

Module size: 60*53*30mm

Scope of application: high -power LED constant current driver, lithium battery charging (including iron electricity), 4V, 6V, 12V, 14V, 24V battery charging, nickel -cadmium nickel -hydride battery (battery group) charging, solar cell board, wind power generator, wind power generator

Output current adjustment method:

1. Adjust the CV potentiometer and set the output voltage to the voltage value you need according to your load requirements.

2. Set up about 30 laps of the CC potentiometer in counterclockwise (that is, set the output current to the minimum), connect to the LED, and adjust the CC potentiometer to the current you need.For the battery charging, after the battery is installed, the output is received, and the CC is adjusted to the current you need.More, the smaller the charging current).
