タイトルまたは説明

Description:

    1. Input voltage range: ***0 v (*0 v to limit the highest voltage). 
    2. Output voltage range:1.*5V - *7V (decompression mode, output must be greater than 2 V above).
    3. Output current: 2 A continuous output.
    4. Output power: the maximum *5 w.
    5 .Ripple frequency: **0 KHZ.
    6. Grain wave peak: **0 mv.
    7. Voltmeter precision: ± 5 ‰ .
    8. Static power: *0 ma (and voltage output voltage and digital tube color is closely related to the actual current will exist deviation). 
    9. Weight: *3g. 
   *0. Size:7cm*4cm.

   *1. With voltage display function, the displayed accuracy is ± 0.*5V, range is 0 - *0V.( Note: in order to voltage display more accurate, please ensure that the voltage is higher than 4V) .
   *2. Button to switch measurement of the or output voltage,and LED indicates the current measurement of the or output voltage;The nixie tube can be turned off by another .Mentioned in these states are able to be memorized, is not lost even if the power is disconnected. 
   *3. Continuously adjustable output voltage range of 1.*5V **7V, ***0V voltage range.(The voltage is at least high than the output voltage of 1.5V). 

   *4. High efficiency,**0 kHz fixed frequency internal oscillator. 
   *5. Guaranteed 3A output load current. 
   *6. Thermal shutdown and current limit protection.
   *7. IN + : positive/IN - : negative.
   *8. OUT + : output positive/OUT - : output negative.
