ITEM NAME:5V-12V Step up to 300V-1200V High Voltage DC-DC Boost Converter Power Modul L7S1 5V-12V Step up to 300V-1200V High Voltage DC-DC Boost Converter Power Modul L7S1 Output current: 2 ~ 20mA.( if you want to add current, pls 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 300V ~ 1200V. When the input voltage is 5V ~ 12V, the output voltage can be adjusted in 300V ~ 1200V. Color:blue Material:CCL 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. Corresponding Products Description: This module is used on security products, stability is fairly good This module with AC output, the output about AC 75V, but can't be adjusted, Product 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. When adjust the output , recommended add a rectifier resistance. Package Contents: 1 x Power module Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
