10A DC-DC Step-Down Adjustable Constant Voltage Module

Input voltage: 7-40V

Output voltage: continuous adjustable (1.25-35V) (applied to input voltage higher than the output voltage can not boost)

Output current: maximum 10A long time 8A (power tube temperature is more than 65 degrees, please add fan cooling, 24V to 12V 5A within room temperature, generally can not use fan)

Constant current range: 0.3-10A (regulation) module more than 65 degrees, please add fan.

Turn the lamp current: constant current value * (0.1), turn the lamp current and constant current value linkage, such as constant current value is 3A, turn the lamp current is set to 0.1 times the constant current (0.1*3A=0.3A), when the value of the constant current regulation into 2A, then turn lamp current is 0.1 times of constant current (0.1*2A=0.2A).

The secondary version is fixed 0.1 times (the actual turn on current is approximate, not very accurate) for charging whether it is full of instructions.

Lowest dropout: 1V

Conversion efficiency: the maximum is about 95% (the higher the output voltage, the higher the efficiency)

Operating frequency: 300KHZ

Output ripple: ripple 50mV (noise free) 20M bandwidth (for reference only) input 24V output 12V 5A measured

Operating temperature: industrial grade (-40 C to +85 C). Please pay attention to the temperature of the power tube, the temperature is too high, please strengthen the heat dissipation

No load current: typical 20mA (24V to 12V)

Load regulation rate: + 1% (constant voltage)

Voltage regulation rate: + 1%

Constant current accuracy and temperature: actual test, the module temperature changes from 25 degrees to 60 degrees, the constant current value change is less than 5% (constant flow value 5A)

Dynamic response speed: 5% 200uS

Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)

Indicator lamp: double color indicator lamp, red indicator in charge, green indicator after charging (no load is green)

Output short circuit protection: there is constant current (constant current value is set)

Input reverse connection protection: none,

Output anti reverse perfusion: No, need additional 2 pole tube for charging pool!

Connection mode: wiring terminal

Module size: 65*47*23.5MM
