Product Description
(Buck-Boost（ZK-SJ4 35W）)
Features:
Buck-boost power supply module Adjustable step-down buck Solar charging Constant voltage constant current SJ4
Improved version! ! ! Used for solar charging.
Exquisite workmanship, strict selection of raw materials, reliable quality.
Introduction:
Wide voltage input 4.8-30V, wide voltage output 0.5-30V, both boost and buck, for example, you adjust the output voltage to 18V, then the input voltage will change between 5-30V, it will output 18V constant; Input 12V, adjust the potentiometer to set any output of 0.5-30V.
High power, high efficiency and better performance than the XL6009/LM2577 solution. Large external power high-voltage MOS, large package high current and high withstand voltage Schottky diode. Increase heat dissipation and copper.
The current can be set to limit the output current, constant current drive, battery charging and other occasions.
It comes with an output anti-backflow function, so you don't need to add an anti-backflow diode when charging the battery.
Product parameters:
Input voltage: 4.8-30V
Output voltage: 0.5-30V
Output current: to long-term stability in the 3A, to strengthen the heat can reach 4A
Output power: natural cooling 35W, strengthen the heat 60W
Conversion efficiency: 88% or so
Short circuit protection: Yes
Operating frequency: 180KHZ
Size: Length * Width * Height 68 * 37 * 22mm
Weight: 39g
Module use:
1. Used as a general step-up and step-down module with overcurrent protection capability
Instructions:
(1) Adjust the CV constant voltage potentiometer so that the output voltage reaches the value you want.
(2) with the multimeter 10A current measurement output short-circuit current (directly to the two test leads can be connected to the output), while adjusting the CC constant current potentiometer so that the output current to achieve a predetermined over-current protection value. (Such as multimeter shows the current value is 2A, then you use the module when the maximum current can only be 2A, the current to 2A when the red constant voltage constant current indicator light, otherwise the indicator light off)
Note: When used in this state, because the output has 0.05 ohm current sampling resistor, connected to the load will be 0 ~ 0.3V voltage drop, this is a normal phenomenon! This voltage drop is not pulled down by your load, but is reduced to the sampling resistor.
Package Included:
1 × Buck-Boost（ZK-SJ4 35W）
