ZVS Drive 3.7V Low Voltage Boost Drive Board, Tapped, with Protection/timing Function, 18650 Power Supply

With timing function
 
 

 

Watch before shooting！

 

  • Board size（long*wide*high）：100mm*25mm*9mm。The height does not include the pin height of the plug-in，Error in manual measurement。
  • One contains the input and output lines for testing，Unless tested，Otherwise, it is recommended to weld the input and output lines directly，There is voltage drop loss in the sub connection。（be careful，Welded ones are not returnable！）
  • Default operating voltage range：DC2.9V~4.2V±0.15V。
  •  
  • Over current protection current10A±2A。
  •  
  • The working voltage is4.2VTime：No load current≤23mA±1mA，

              Enter protection mode or stop working current≤6mA±1mA，

              ShutDown Current ≤0.9mA±0.1mA。

  • power≥30W。
  • This board is suitable for3.7V 18650Power battery power supply，proposal2More than one node in parallel，discharge rate 3Cabove，Single section capacity2000mAHabove。
  • be careful，The protection of this board is mainly used for the protection of this board，The battery itself is also recommended to be protected。
  • white4PThe seat is the input：be marked with+ +Connect the battery positive pole，be marked with- -To the negative pole of the battery。
  • white6PThe seat is the output：Middle two（OUTM）Connected to transformer primary tap，The other two sides are connected to the two sides of transformer primary。
  • Over temperature protection temperature point62℃±5℃。
  • LEDThe lamp is a multi state indicator。
  • Key：

    AN1andAN2It is a multi-function key。

  AN1It is tentatively designated as shutdown button（Other functions can be customized，Charge as appropriate），At work，When the press time exceeds30ms，The board stops working，LEDThe light goes out，Enter shutdown state。

  AN2Key for startup and shutdown：In shutdown state，Click（12mSabove，The same below）The back panel starts to work；when in use，Press three times to enter the shutdown state。

 （The two keys cannot be pressed at the same time，You can customize the function of pressing two buttons at the same time，Charge as appropriate）

 

  • It can only be used to drive high frequency transformers at present，Turns2.5T+2.5Tabove，Middle tap。Note that the input power should be controlled within40Wwithin。
  •  
  • Normal operation：Press the start key，delayed0.5Start working in about seconds，LEDThe lamp is always on。Time without timing function，Normally it works all the time。
  •  
  • Over current protection：When excessive input current is detected，Enter over current protection，Will stop the output，LEDLamp with0.3Blinks quickly at intervals of seconds。When the input current is detected to be lower than the set value，Exit over current protection。
  •  
  • Over temperature protection：When the detected temperature is too high，Enter over temperature protection，Will stop the output，LEDLamp with1Seconds interval；When excessive temperature is detected for more than260mS，It will delay6second（LEDtwinkle6second）And the detected temperature is lower than the set value，Exit over temperature protection。
  •  
  • Low voltage protection：

  When the input voltage is detected≤2.9V±0.15VTime，Enter low voltage protection，Will stop the output，LEDLamp with bright2Second off0.5Blinking at intervals of seconds；

  When the input voltage is detected≥3.4V±±0.15VTime，Exit low voltage protection；

  When the low voltage protection is entered and the input voltage is detected≤3.4V±0.15VMore than30second，Automatically enter the shutdown state。

 

.The timing cycle work can be opened and the timing mode can be selected through the dial code on the board，One of dial switch、Two、Three and0、1Screen printing on the corresponding board。The following is the default timing，It can be changed according to the buyer's request（There is no extra charge for simple timing changes）
