shockley XL4015 DC-DC Buck Converter Step Down Lithium Battery Charger Module (2 Pc) Multipurpose Controller

Specification: Input voltage: 4 -38 V Output voltage:1.25 -36 V continuously adjustable Output current:Adjustable maximum 5A Output power:Max 75 W Working temperature:-40 ~ ++ 85 degrees Working frequency:180 KHz Turnover efficiency:Maximum 96% Short circuit protection:(Limited flow 8A) About temperature protection:Yes (about temperature, automatic turn off output). Input Reverse Connection Protection:No, if necessary, input a high flow diode into the input. Installation:4 3mm wires. Connection mode:Terminal, V -IN as input and V -OUT as output. Module size:Approx. 61.7*26.2*15mm/2.42*1.03*0.59in Features: Triple:(1) Use as a normal blood pressure modules with overcurrent protection capability;(2) As the various voltage lithium batteries, batteries, charger for solar panels, wind turbines and other occasions;(3) Used as a high-power LED constant current drive module; With constant pressure and constant current modes, there are light indicates which mode is currently in module;4. When used as a lithium battery charger, you can set the float voltage and the charge current size, there is light indicates is being charged or has been filled; Has the current limit protection, output short circuit even if it will not burn module. This module uses machine placement, and each module shipments have been two hours before the aging tests to ensure high reliability. Overtemperature protection: (automatically shut off the output after overtemperature)?Input reverse polarity protection: None, (if necessary, please enter the string into the high current diode).
