XT-XINTE 35W Constant Voltage Constant Current Adjustable Buck-Boost Power Module with LCD LCD Digital Display Voltage Ammeter
product description:
Brand: XT-XINTE
color: blue
specification:
Size: 66 * 48 * 21mm
Weight: 46g
Input voltage: 5.5-30VDC (When the input voltage is 5V, the voltage can be increased or decreased, but the voltage and current measurement is not accurate; when the voltage is lower than 4.7V, the undervoltage protection)
Output voltage: 0.5-30VDC adjustable
Output current: 0.2-3A adjustable, enhanced heat dissipation can reach 4A (please strengthen heat dissipation when the module temperature exceeds 65 degrees) with constant current indicator, the output power should not exceed 35W or the current should not exceed 4A during low voltage output Bad and unwarranted!
Voltage display resolution: 0.05V
Current display resolution: 0.005A
Conversion efficiency: about 88%
Features:
1. LCD can display input and output voltage, output current, power;
2. Input terminal anti-reverse protection (please do not connect as much as possible, there are +-characters on the board, first confirm the positive and negative before wiring power);
3. Can step up and step down, the output voltage can be adjusted arbitrarily from 0.5-30V, and the current can be adjusted arbitrarily from 0.2-4A;
4. Anti-backflow protection at the output end, no need to add anti-backflow diode when charging the battery;
5. The button controls the ON / OFF state of the output terminal, and can be set to ON or OFF by default upon power-on;
6.Using the step-up and step-down chip as the main controller, external 60V 75A MOS tube as the switching tube, dual 60V 5A SS56 Schottky for rectification, 60V withstand voltage value, which is better than XL6009 / LM2577 immature solution on the market The withstand voltage of the device is insufficient. The withstand voltage of the MOS tube and the Schottky diode must be greater than the input plus the input voltage.)
7. The output ripple is small, with LC filtering.
8. Contains heat sink, send module to support isolation column.
note:
When this module is used over 3A, 35W, please strengthen the heat dissipation!
The input IN- of the module is forbidden to be shorted with the output OUT-, otherwise the constant current function is invalid.
Please ensure that the power of the power supply is always greater than the power required by the output load!
If the module wants to output at full load, the input voltage must be more than 8V. When the input voltage is 5V, the output power is about 15W, and the voltage and current meter is invalid. The current value of the module is 4A, the premise is limited by the large output power, such as output 17V, the current should not be greater than 2A.
The module has output short-circuit protection. After the short-circuit protection, the module automatically turns off the output, and it can be restored by powering on the module again. If your power supply does not have output current-limiting protection, it is recommended that a fuse be connected in series to the front of the module input to increase the safety factor.
The module has an input undervoltage protection function. The default value is about 4.7V. When the value is lower than this value, the output will be automatically disconnected, and the module can be restored by powering on again (note the voltage at the port of the module. When the input current is relatively large, (Do not ignore the voltage divider on the input leads).
