Descriptions:
Calibration Method: This module has calibration function, do not worry measurements show allowed to question, if you can find that are not allowed to display the following method calibration. Just for the first time using a calibrated once!
Voltage Calibration: loss of power, hold down the “set” key, and power on, to enter the voltage calibration mode, the LCD screen starts flashing, release the setting key, press the “Settings” button to add, “OK” for the reduction, alignment to the correct input voltage, such as: the input voltage is 12.65V, then the voltage was adjusted to 12.65V, are automatically saved after 2 seconds, power is withdrawn calibration is complete!
Special note: When the baby just received a customer reflect the output voltage can not be adjusted, because the module factory default output voltage of about 20V. When you encounter this problem, first counterclockwise rotation ADJ-V potentiometer 10 laps or more, until the voltage value changes only, then use the module can be properly adjust the voltage.
Module parameters
Input voltage: 7V-36V
Output voltage: 1.5-35V adjustable (can only be done step-down module, the input must be greater than the output of 1.5V or more)
Output current: adjustable, 10A (recommended in 8A, 5A 70W or less at room temperature can be natural cooling, please enhance heat dissipation exceeds oh .proposes to add a small fan .constant current need to adjust the output voltage of 2V or older to current regulation!! only in the constant state will play a role.)
Output Power: Max 150W (recommended in 100W, large pressure, please reduce power use)
Working temperature: -20 ~ + 75 degrees (note the use of the power transistor temperature exceeds please enhance heat dissipation)
Operating frequency: 300KHz
Conversion efficiency: up to 95%
Short circuit protection: Yes, constant current value currently set
Input Reverse Polarity Protection: None
Anti-reflux output: No, please add a diode for charging!
Installation: up and down both sides of the acrylic sheet, eight pillars, eight 3mm screws, turn the key easier to install when you install Oh!
Connection: terminals or solder terminals, VIN is the input, VOUT output
Module dimensions: length 80mm width 53mm height 35mm
Weight: 132g
Setting Description:
Setting key to set the display mode is divided into three types:
1, F-0 mode: Display output voltage;
2, F-1 mode: Display input voltage;
3, F-2 mode: alternating input and output voltage;
Instructions: Press the “Settings” button to cycle through the three display modes, the corresponding indicator will be on or off, press the “OK” button to save and exit, a separate press “OK” button to switch backlit LCD screen.
Applications
1. Use as an ordinary step-down modules with overcurrent protection capabilities
Instructions:
(1) under no-load conditions, adjust the “constant voltage potentiometer ADJ-V”, so that the output voltage reaches the value you want;
(2) outputs directly shorting module (coarse find articles or forceps wire shorted to the output terminal, NOTE: Do not short-circuited when the tune voltage), then adjust the “constant potentiometer ADJ-I” make display the current value reaches the preset value of the overcurrent protection; (such as on-board ammeter shows the current value of 4A, then the module maximum current is limited to 4A, 4A constant current LED current to the red light)
(3) connected to the load and work.
2. Use as a battery charger
Instructions:
(1) determines that the battery float voltage and charging current; (lithium parameters if 3.7V / 2200mAh, then float voltage of 4.2V, the maximum charging current 1C, namely 2200mA)
(2) under no-load conditions, adjust the “constant voltage potentiometer ADJ-V” so that the output voltage reaches the float voltage;
(3) outputs directly shorting module (coarse find articles or forceps wire shorted to the output terminal, NOTE: Do not short-circuited when the tune voltage), then adjust the “constant potentiometer ADJ-I” make displays the current value of the charging current reaches a preset value;
(4) Charge turn lamp current factory default is 0.1 times the charging current; (Battery during charging current is gradually reduced, gradually converted to constant voltage charging by the constant current charging, if the charging current setting is 1A, then when the charging current is less than 0.1A when charging indicator light off yellow, full blue indicator lights up and the battery is fully charged), charging is complete, disconnect the battery terminals, then disconnect input off to prevent battery reflux damage the module!
(5) connected to the battery charge.
3. Use as a constant current LED driver module
(1) determine that you need to drive the LED operating current and the maximum operating voltage;
(2) under no-load conditions, adjust the “constant voltage potentiometer ADJ-V” so that the output voltage reaches the LED operating voltage;
(3) outputs directly shorting module (coarse find articles or forceps wire shorted to the output terminal, NOTE: Do not short-circuited when the tune voltage), then adjust the “constant potentiometer ADJ-I” make the current value reaches the preset display LED current;
(4) connected to the LED, the test machine.
