DC-DC Converter 5-30V to 1.25-30V Automatic Step UP/Down Converter Boost/Buck Voltage Regulator 8A Charger Power Supply Board
Features:
This is a non-isolated DC regulated power converter module with long service life.
High power and stable output, it converts 5-30VDC to 1.25 -30VDC.
High quality components ensures high conversion efficiency, up to 93%.
It supports over current, short circuit, over temperature protection.
Designed with two heat sinks for better heat dissipation.

Overcurrent protection: Yes
Short-circuit protection: have (current limiting protection)
Overtemperature protection: there is (automatically reduce the output voltage after overtemperature)
Input backconnect protection: none (please insert diode in input string if necessary)
Output anti-reverse irrigation: Yes, it does not need to add anti - reverse diode when charging.
Wiring mode: terminal output, (IN is input, OUT is output)
Module size: 60mm*53mm*22mm (length, width and height)
Scope of application:
This module can be used in the field where the input voltage fluctuation is relatively large and the output requirement is relatively stable. Such as:
1. 12V battery (10-14V) voltage regulator output 12V, supply power to 12V equipment, 24V battery voltage regulator 24V; It can be used as an on-board power supply
2. Solar panel voltage regulation, solar panel voltage fluctuation is relatively large, this module can be voltage regulation output, power supply equipment or battery charging use.
3. Drive high-power LED lights, constant current drive, such as 12V battery drive 4 series of LED lights, this time LED and battery voltage difference is not big.
Output current regulation method:
1. Adjust CV potentiometer, according to your load requirements, set the output voltage to the voltage value you need.
2. Counterclockwise set CC potentiometer about 30 laps, (that is, the output current is set to. Small), connect the LED, adjust the CC potentiometer to the current you need. For battery charging, put the battery after the power, and then receive the output, CC to the current you need, (for charging must be used to put the power of the battery to adjust, because the battery remaining in the power more, the smaller the charging current.) Do not adjust the current by short circuit. The circuit structure of the module cannot be adjusted by short circuit.
Note:
1. Due to the light and screen difference, the item's color may be slightly different from the pictures.
2. Please allow 1-3cm differences due to manual measurement.
Package Included:
1x Power Supply Board
