100% brand new and high quality.Features:This module is used on security products, stability is fairly good.The capacitor can be charged, but charging speed is somewhat slow, please note.As the module power output module, it is not possible for the sensor.This module with AC output, the output about AC 75V, but can't be adjusted.The output are generally stable, of course, if you test the output voltage is unstable, you can add a limiting current resistor for testing, usually this problem does not occur.Specifications:Output current: 2 ~ 20mA.When the input voltage is 5V, the output voltage can be adjusted in 280 ~ 1200V.When the input voltage is 6 ~ 12V, the output voltage can be adjusted in 400 ~ 1200V.Material: Metal and P1asticSize: approx.64x31mm/2.52x1.22inColor: As pictures shownQuantity: 1 PcNote:No retail package.Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
