Yeeco 4-40V to 1.2-38V Car DC DC Buck Converter Step-down Power Supply Constant Voltage and Current Adjustable Voltage Regulator Volt Convert for Battery Charging LED Driver with Volt Amp Ammeter Voltmeter Display and USB Output

Module Name: step-down constant current module with digital display
Module Properties: non-isolated step-down module (BUCK)
Input voltage: DC 4-40V
Quiescent Current: 5mA without voltmeter ammeter
Output voltage: DC 1.2-38V continuously adjustable
Output Current: 3A MAX,Please enhance heat dissipation exceed 2A
(With the input, the output voltage difference,The greater the voltage difference between the output current is smaller)
Constant current range :0.1-3A
Output power: = Output voltage * 3A
Such as: Output 5V * 3A = 15W, 12V * 3A = 36W, 24V * 3A = 72W,
Operating temperature: -40 to +85 ° C
(ambient temperature is too high, please enhance heat dissipation)
Operating Frequency: 150KHz
Conversion efficiency: up to 95% (efficiency is related input,output voltage, current, voltage difference )
Current protection: yes (constant current set value)
Short circuit protection: Yes (constant current set value)
Input Reverse Polarity Protection: None, (if required in the input string into the diode)
Output prevent anti-irrigation: none, (if required in the output diode in series)
Identification resistor: Tablet PC, pad, phone (some phones identification circuit is different, need to be adjusted)
Voltmeter minimum resolution: 0.05V/0.05A (10V following automatic switching decimal point)
Installation: four pcs 3mm screws Wiring: no need welding output terminals
Module dimensions: length 60mm *width 35mm* height 20mm
