DESCRIPTION
This module can be applied to fields in the input voltage is higher than the step-down output voltage, such as batteries, power transformers, DIY adjustable power supply, 24V Car T of the power equipment industry buck, 12V switch 3.3V, 12V switch 5V, 24V switch 5V, 24V switch 12V, 36V 24V turn and so on.
FEATURES
- Product size: 66mm * 38mm* 14mm (l x w x h)
- Colours :Blue
- Package Weight: :31g
- Materials: FR4 + electronic components
- Name: XL4015 5A ADJ DC - DC Step Down Adjustable With Digital Display Screen
DETAILS
- 1. Display with voltmeter, voltmeter error of ± 0.1V, Range 4 ~ 48V. (Note: The input voltage is below 4V, the onboard voltage display table does not work)
- 2. Mass 5 * 5 Touch button to switch measuring input or output voltage, and has a light show which is being measured terminal voltage. The initial power-on default digital display input voltage and the input IN indicator lights; touch of a button, the digital display output voltage and the output OUT indicator lights. And to keep the final set, then turn off even
- 3. Voltmeter can be turned off, press the switch more than one second and less than 4 seconds, you can let go off. After voltmeter switch closed as long as the short press to open a voltmeter.
- 4. The input and output voltage measurement error than the standard function, press the switch more than 4 seconds, let go after entering voltage measurement error than the standard features, this time IN lights (calibration input), the digital display flashes compared with a positive value (factory parameters 0.0), then press the button to change the value (value in the range of -0.5 to 0.5, the unit is V), a positive number indicates upward calibration, negative number indicates downward calibration. After adjusting the input calibrated value side, long press the button more than 2 seconds, let go into the error correction output terminal, then OUT lights (calibration output terminal), and displays the same calibration value output terminal, adjustment method and the input, the whole good after comparing the output of the reference value, press the button more than 2 seconds, let go to save the set value and return to normal display voltage correction value is set to take effect immediately, and non-volatile. (With this feature, you can meet your requirements for higher accuracy)
- 5. The band terminals, no iron can also be easy to use, and retention wire terminal points (Must be greater than the input voltage to output voltage is high 1v above)
- 6. The maximum output current of up to 5A, recommended operating current of about 4A.
NOTES
- 1. When the module output voltage can not be adjusted, the output voltage is always equal to the input voltage.Please adjust the potentiometer counterclockwise 20 laps or more. (Let potentiometer against your chest, counterclockwise turn boost) .
- 2. Input voltage must be higher than the output voltage of 1.5v or more
- 3. high current or high power needed to enhance heat dissipation
