20A 1200W DC Converter Boost Step-up Power Supply Module 8-60V to 12-83V
close

Specifications:
 
Module name: 1200W boost constant current module
Module properties: non isolated boost module (BOOST)
Input voltage: 10-60V
Input current: 20A
Quiescent operating current: 15mA
Output voltage: 12-83V continuous adjustable
Output current: MAX 12A over 20A, please strengthen the 
cooling (with input and output differential pressure, the greater 
the pressure difference between the output current is small)
Constant current range: 0.3-20A
Output power: = input voltage  x 10A
Working temperature: -40~+85 degrees 
Working frequency: 150KHz
Conversion efficiency: ≤95% (efficiency and input, output voltage, 
current, pressure difference)
Installation: 4pcs 3mm column
Connection mode: welding output (please use big current and pure copper wire)
Module size: 130mmx52mmx46mm(LxWxH)
 
Feature:
 
1.Over current protection: there is a certain range of error in the input over 30A, 
automatically reducing the output voltage.
2.Short circuit protection: there is (input 40A fuse) double short circuit protection, 
use more secure.
 
When using the boost power supply should pay attention to the following points:
 
1. Input power supply voltage must be above 10V.
2. When the power supply is used for the input power supply, the input power and 
the output voltage of the input power supply are the first to be unloaded. Then pick 
up the load. (must ensure that the switching power supply has been working).
3. When the constant current mode is used to set the voltage, the constant voltage 
must be higher than the input voltage.Do not use the way of short circuit output current,
 the circuit structure of the boost module can not be adjusted in short circuit way.
4. If the input voltage fluctuation range is lower than the set output voltage,
then the output voltage is constant, it is to ensure that input is lower than the output voltage.
 
Package included:
 
1 x 1200W boost constant current module

Application range

This controller is only suitable for ordinary solar modules. Please do not connect other charging power sources, otherwise the controller may be permanently damaged. 
This controller is only suitable for the following 12V/24V battery types: 
ordinary electrolyte lead-acid battery, 
maintenance-free lead-acid energy storage battery, deep cycle battery, gel battery 
warning! This controller is not intended for nickel-cadmium batteries, nickel-metal hydride batteries, lithium batteries, and other types of rechargeable or non-rechargeable batteries.

Installation and connection

Install the controller in the appropriate location and keep it as close as possible to the battery. The mounting surface must be solid and flat, dry and not easily ignited. The battery cable must be as short as possible and match the appropriate cable cross-section (eg 4mm2 20A current, 2m length). 
If the battery is operated within a large temperature range (summer/winter), be sure to install a temperature-controlled probe (if any) words). A temperature-compensated charging voltage extends battery life and increases available power. 
To ensure air circulation, keep a 10cm spacing around the controller. 
During the installation process, connect the components in the following order. 
1. Connect the positive and negative terminals of the battery to the positive and negative terminals of the controller. 
2. Connect the positive and negative poles of the solar module to the positive and negative terminals of the PV input of the controller. 
3. Connect the load to the positive and negative terminals of the controller's load output port. 
When disassembling, proceed in the reverse order. 
WARNING: Incorrect installation sequence can result in damage to the controller.
