3.0 WATT SWITCHING PCB MOUNT POWER SUPPLY INPUT: 85-264VAC OUTPUT: 3.3VDC 0.5A

2.5 WATT SWITCHING PCB MOUNT MODULAR POWER SUPPLY; INPUT=85-264VAC / 70-400VDC OUTPUT=5VDC 0.5A. DC-DC CONVERTER

Module parameters: Input voltage: 6V-32V Output voltage: 1.5-32V continuously adjustable (can only be used step-down module, the input must be greater than the output 1.5V or more) Output current: adjustable, the maximum 5A (recommended in the use of 4.5A, when exceed 3A or 35W the best to strengthen the cooling! Suggest using a small fan at the input terminal! Constant current requires an output voltage of 2V or more to be adjusted, the current regulation, only in the constant current state will work, constant current is mainly directly used to the low resistance battery charge or LED working current limit and other use, please make sure about this before you order it. Output power: up to 75W (recommended in the use of 50W, if uses large pressure difference, please reduce the power) Operating temperature: -20 to +70 degrees (pay attention to the power tube temperature, when exceed please strengthen the cooling) Operating frequency: 180KHz Conversion efficiency: up to 96% Short circuit protection: Yes, constant current Current set constant current value Over-temperature protection: Yes (over-temperature automatically turn off the output) Input reverse protection: Yes Output reverse flow: None, for charging please add a diode! Installation: 8pcs pillars, 8pcs 3mm screws Wiring method: wiring terminal or soldering terminal, VIN for the input, VOUT for the output Module size: 65.6mm x 40mm x 25mm (L*W*H) Weight: 77g Calibration method: The module has a calibration function, don't worry about measuring inaccurate problems, if you find the measurment is not inaccurate you can use the following methods calibration. Just need to calibration once for the first time! Voltage calibration: In the case of power down, press and hold the "SET" button, power on, enter the voltage calibration mode, the LCD screen starts to flash, release the set button, press the "Set" key to add, "OK" to reduce, calibrate correct input voltage, such as: the input voltage is 12.65V, then adjust the current voltage to 12.65V, after 2 seconds it automatic save, power off and exit to complete the calibration! Current calibration: For no-load current display, or current is too large! In the case of power off, press and hold the "OK" button, power on, enter the current calibration mode, the LCD screen starts to flash, release the "OK" button, press the "Set" button to add, "OK" button to reduce, calibrate correct current, such as: no load display 0.02A, then adjust to 0.00A, after 2 seconds it automatic save, power off and exit to complete the calibration! Special Note: Some customers feedback that the output voltage can not be adjusted, this is due to the factory default voltage is 20V. When you encounter this problem, please counterclockwise rotation ADJ-V potentiometer 10 laps above, until the voltage value changes, and then the module can be normal adjustment of the voltage. Note: USB output voltage and the module output voltage needs to be consistent, when the USB indicator does not light, means USB has no output, when the USB light is set, it is not fixed 5V output, when charging USB device please make sure the voltage is 5V, if higher than 5.5V screen will flash, it will be reminded to adjust the voltage, otherwise it may damage your device, USB output power is turned off by default, to ensure that mistakenly plug USB will not damage the device. Setting Description: Setting key can be set to four kinds of display mode: 1. F-0 mode: display output voltage; 2. F-1 mode: display input voltage; 3. F-2 mode: alternately display input and output voltage; 4. USB mode: display USB output voltage and turn on or off the USB output; Instructions: press the "set" button, the cycle shows four kinds of display mode, the corresponding indicator light will on/off, press the "OK" key to save and exit, press the "OK" button to switch the LCD backlight. Package includes: 1 x 5A DC-DC Adjustable Step Down Power Supply Module (Board color will send in random)
