  • –Large external power tall voltage MOS, large package high current and high withstand voltage Schottky diode. Add heat dissipation and copper.
  • –The current can be set to limit the output current, constant current drive, battery charging and other occasions.
  • –It has output backflow prevention.

.

Feature:

1. Wide voltage input 4.8-30V, wide voltage output 0.5-30V, including step-up and step-down, for example, you adjust the output voltage to 18V, then the input voltage will vary between 5-30V, it will output 18V constant; input 12V, adjust the potentiometer to set any output from 0.5-30V.
2. It has output backflow prevention, so there is no need to add anti-backflow diodes when charging the battery.

Description:
Product Name: Voltage Regulator Module
Input voltage: 1.8-30V
Output voltage: 0.5-30V
Output current: 3A for long-term stable operation, up to 4A with enhanced heat dissipation
Output power: natural heat dissipation 35W, enhanced heat dissipation 60W
Conversion efficiency: about 88%
Short circuit protection: Yes
Working frequency: 180KHZ
Size: 68 x 37 x 22mm, installation hole diameter 3mm
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-value current protection (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 indication light, otherwise the indication 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 thing! This voltage drop is not pulled down by your load, but is reduced to the sampling resistor.
2. Used as a battery charger:
Non-constant current function of the module can not be used to charge the battery, due to the power consumption of the battery and the charger is very large, resulting in charging current is too large, resulting in battery damage, so the beginning of the battery to use constant flow charge, when the charge to a certain extent, when the automatic switching back to constant voltage charging.
Instructions:
(1) to determine the rechargeable battery you need to recharge the battery voltage and charge current, if the lithium battery parameters of 3.7V / 2200mAh, then the float voltage of 4.2V, the maximum charge current of 1C, or 2200mA.
(2) no-load conditions, the multimeter to measure the output voltage, adjust the constant voltage potentiometer so that the output voltage to float voltage; (if the 3.7V lithium battery charge, the output voltage can be adjusted to 4.2V)
(3) with a multimeter 10A current measurement output short-circuit current (directly to the two test leads can be connected to the output), while adjusting the constant current potentiometer so that the output current reaches a predetermined charge current value;
(4) Charging Turn the lamp current factory default 0.1 times the charging current. (The battery in the process of charging the current is gradually reduced, and gradually from constant current charging to constant voltage charging, if the charge current is set to 1A, then when the charge current is less than 0.1A, the blue light off, green light Since the battery charge is completed)
(5) connected to the battery, charging.
(Steps 1, 2, 3, 4 are: input termination power supply, the output does not load the battery)
3. Used as a high power LED constant current drive module
(1) determine the operating current and maximum operating voltage you need to drive the LED;
(2) under no-load conditions, multimeter to measure the output voltage, adjust the constant voltage potentiometer to the output voltage to LED maximum operating voltage;
(3) Measuring the output short-circuit current with the multimeter 10A current level while adjusting the constant current potentiometer so that the output current reaches the predetermined LED operating current;
(4) connected to the LED, test machine.
(Step 1, 2, 3: input power supply, the output no load LED lights.)
Note: This module in more than 3A, 35W use, please strengthen the heat!
Packing list:
1 x Module
Note:
1. Due to manual measurement, please allow 1-3cm error. Make sure you don't mind before bidding.
2. Due to the difference of different monitors, the picture may not reflect the actual color of the product. Thanks.
