Step Up/Down Buck Boost Converter Power Supply Modul USB Type-C Micro Input 5V to 3.3-24V Voltage Current Adjustable Switch | Инструменты

Description: This is an instrument with integrated buck-boost power supply module and multi-function voltage ammeter and temperature display module. In ‘PER’ work mode, it can be used as buck-boost power supply module. It can convert to DC 3.5V~12V to DC 1.0V~24V and power is about 2W~3W. In ‘VAH’ work mode, it can be used as multi-function voltage ammeter. It can be used to measure voltage, current, power, battery capacity, discharging time. It also can display real time temperature in both work modes. It is very suitable for technical engineers to develop, debug instrumentation, after-sales engineers travel maintenance, etc. Feature: Dual operating system Support power supply output function Support test power function Support real time temperature display Support over power protection Support under-voltage protection Support over-current protection LCD high definition display Automatic calibration Multi-parameter simultaneous display Support power saving mode Three voltage input methods Support voltage and current calibration Parameter: Work Voltage:DC 3.5V-12V Output Voltage:DC 1.0V-24V Output Power:3W(MAX) Maximum output power within 2W when output DC 1.2V~2V Maximum output power within 3W when output DC 2V~20V Maximum output power within 2.5W when output DC 20V~24V Output voltage accuracy:+/-0.5% Output voltage accuracy:+/-1% Measure voltage range:DC 0~35V Measure current range:0~3A Measure power range:0~110W Measure battery capacity range:0~9999Ah Discharging time:0~100hours Measure temperature:-20℃~70℃ Work Temperature:-40℃~85℃ Work Humidity:0%~95%RH; Mode Switching: The default is the Power Output Mode PER at first Keep press button ‘ON/OFF’ for 10 second to switch mode When power is remove, module can remembers current operating mode. The default work will be the same mode when power on at next time. Power Output Mode PER: Input from standard USB male socket, Micro USB female socket and Type-C female socket. Output from ‘OUT+’ and ‘OUT-'. The ‘COM’ terminal can not be used at PER mode. LCD display will display current mode ‘PER’ when start up. And there is a symbol ‘OUT’ when work in PER mode. Terminal ‘COM’ unavailable at PER mode. Short press button ‘ON/OFF’ to turn ON or OFF output voltage. At this time, screen will display 0V. Keep press button ‘ON/OFF’ for 2 second to switch display output current or output power at the second line. Keep press button ‘ON/OFF’ for 5 second to turn ON or OFF display screen backlight. But the module can output voltage normally. Keep press button ‘ON/OFF’ for 10 second to turn switch work mode PER or VAH. Short press button ‘UP’ and ‘DOWN’ to adjust the output voltage. User also can keep press to adjust the output voltage continuously and greatly. There is a symbol ‘SET’ will display at the same time. Automatically save the set parameters after 2 second. Short press button ‘UP’ and ‘DOWN’ to switch display current temperature when turn OFF power supply output. Supports over-power protection. It will automatically stop output voltage and the LCD will display ‘OPP’ and flash if output power is more than 3W. Supports under-voltage protection. It will automatically stop output voltage and the LCD will display ‘LVP’ and flash if output voltage is less than 0.8V. Supports over-current protection. It will automatically stop output voltage and the LCD will display ‘OCP’ and flash if output current is more than 2A. The module does not support reverse connection protection, please do not short circuit and reverse. Multi-function Meter Mode VAH: Module work voltage: Standard USB male socket, Micro USB female socket and Type-C female socket are used to provide work voltage for this module. Measuring voltage: ‘V’ and ‘COM’ terminals are used to measure Measured Device Voltage. Measuring current: ‘A’ and ‘COM’ terminals are used to measure Measured Device Current. There is a symbol ‘IN’ when work in PER mode. Short press button ‘ON/OFF’ to switch display current temperature or Measured Device Voltage. Keep press button ‘ON/OFF’ for 5 second to turn ON or OFF display screen backlight.But the module can output voltage normally. Keep press button ‘ON/OFF’ for 10 second to turn switch work mode PER or VAH. Short press button ‘UP’ and ‘DOWN’ to switch display Measured Device Power and current. And also can measure Battery capacity, Battery discharging time if connect battery. The module does not support reverse connection protection, please do not short circuit and reverse. Calibrate Voltage/Current: Calibrate Voltage: Keep press button ‘ON/OFF’ before power ON and then power ON and release button after 5 second. Automatically enter calibration mode. The voltage display will flashing. Short press button ‘UP’ and ‘DOWN’ to adjust and calibration voltage. Enter current calibration mode if keep press button for 2 second. Automatically save parameters and return to the normal display interface if keep press button for 5 second. Calibrate Current: Enter current calibration mode if keep press button for 2 second after Calibrate Voltage. The current display will flashing. Short press button ‘UP’ and ‘DOWN’ to adjust and calibration current. Automatically save parameters and return to the normal display interface if keep press button for 5 second. Voltage and current need to be separately calibrated separately in different work modes. The same way of calibration. Usage: Connect to power supply from input terminal Set work mode by keep press button ‘ON/OFF’ for 10second Connect load or Device Voltage Set required parameters Test and use Application: Ordinary low power supply Voltmeter Ammeter Battery capacity tester Battery load capacity tester Temperature monitor
