Feature:Module size: about 25 * 48mm (W*L)Output current: 2-20mA. ( if you want to add current, please put insurance below the transformer replaced the 0-ohm resistor, maximum 50mA, but does not recommend increased.)When the input voltage is 5V, the output voltage can be adjusted in 300-900V.When the input voltage is 6-12V, the output voltage can be adjusted in 400-1200V.The capacitor can he charged, but charging speed is somewhat slow, please note.As the module power output module, it is not possible for the sensor.Corresponding products description: This module is used on security products. stability is fairly good.The module with AC output, the output about AC75V, but cann't be adjusted, wiring: 1. Fire line connect VCC, Zero line connect its joinsProduct test pattern:Please refer to the main map, new products 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.Package includes:1 x DC-DC Boost ConverterTesting:
