XL6009 Boost Step-up Module Power Supply LED Voltmeter

Features:

1 with a display voltmeter , voltage meter error ± 0.1V, range . 5 ~ 35V. (Note: The input voltage is below 4.5V, the onboard voltage meter does not work not shown)

2. Large Volume 5 * 5 Touch key to switch the measurement input or output voltage , and indicator light display which is being measured terminal voltage . Digital display default initial input power voltage, and the input indicator IN lights; touch of a button, the output voltage of the digital display, and the output OUT indicator lights. And to keep the final set, then turn off even

3. A voltmeter may be closed , press more switches 1 second and less than 4 seconds, can be let go off . After voltmeter switch closed as long as the press to open voltmeter.

4. The input and output voltage measurement error calibrating function , press more switches 4 seconds after let go into the measurement errors of voltages than the standard function, this time IN lights (calibration input), the digital value representing flashing display (default parameters 0.0), then press the button can change the value (value range -0.5 to 0.5, the unit is V), a positive number indicates an upward calibration, negative number indicates that the calibration downwardly. After adjusting the input calibrated value side, press more button for two seconds, let go into the error calibration output terminal, in which case OUT lights (calibrated output), and displaying the same calibration value output, adjustment method and the input terminal, the whole good after the calibrated value of the output terminal, press more button for two seconds, let go after saving the set values and return to normal display voltage correction value is set to take effect immediately and non-volatile. (With this feature, you can meet your higher precision)

The terminal strip, no iron can be easy to use, and retain the wire bonding terminal points

(Input voltage to be output must be higher than the above 1v)

6. The output current up to the maximum . 3A , recommended operating current of about 2A, 2A exceeds plus fins

7. The use of the internal oscillation frequency of 400KHz, a second-generation switching voltage regulator, low power consumption, high efficiency

Instructions:

1. The input and output voltages than the standard error of measurement: Press more switches 4 seconds after let go into the measurement errors of voltages than the standard function, this time IN lights (calibration input), the digital value representing flashing display (factory parameters 0.0 ), then press the button can change the value (value range -0.5 to 0.5, the unit is V), a positive number indicates an upward calibration, negative number indicates that the calibration downwardly. After adjusting the input calibrated value side, press more button for two seconds, let go into the error calibration output terminal, in which case OUT lights (calibrated output), and displaying the same calibration value output, adjustment method and the input terminal, the whole good after the calibrated value of the output terminal, press more button for two seconds, let go after saving the set values and return to normal display voltage correction value is set to take effect immediately and non-volatile. (With this feature, you can meet your higher precision)

2. Close voltmeter : Press switch for more than one second and less than four seconds, can let go off . After voltmeter switch closed as long as the press to open voltmeter.

Precautions:

1. recommended power usage exceeds 20W , the need to add heat sinks to enhance cooling ;

2. a customer module to reflect the output voltage can not be adjusted , it is always equal to the input voltage. When you encounter this problem, please counterclockwise rotary potentiometer more than 10 laps, and then use module can properly adjust the voltage.

Applications:

    This module can be used in the field of boosted output voltage higher than the input voltage of the input, such as a battery, power transformers, DIY adjustable power supply, 24V car T of the power supply, industrial equipment buck, 9 turn 12 is V , 12Vturn 18 V , 18 is V switch 24 V and the like.
