100% brand new and high quality Features: Made of high quality electronic components, it is solid, durable, good conductivity and high performance, long service life. 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. Please pay attention that the capacitor can he charged, but charging speed is somewhat slow. As the module power output module, it is not possible for the sensor. This module features protection functions, so its stability is fairly good. The module with AC output, the output about AC75V, but cant be adjusted, wiring: 1. Fire line connect VCC, Zero line connect its joins. Boost module only, other accessories demo in the picture is not included Specification: Model: GT1000V Material: Circuit Board, Electronic Components Input voltage: 5-12V DC input Output voltage: 300V-1200V Size: app.7 x 1.1cm/2.75 x 0.43in Color: Wood Quantity: 1 Pc Instruction: Module control terminal: There are 3-wire interfaces, all interfaces have wiring terminals, which is convenient for users. 1. DC +: DC positive electrode. 2. DC-: DC power negative. 3. CH1: Input detection interface, active high. Relay output: There are 3-wire interfaces, all interfaces have wiring terminals, which is convenient for users. 1. NO: The interface of relay is normally open, and it is suspended before pull-in, short-circuited to COM1 after pull-in. 2. COM: Relay common interface. 3. NC: The interface of relay is normally closed, and it is connected with COM1 before pull-in, and suspended after the pull-in Load capacity: Normally open port max.load capacity: DC 0-30V/10A, AC 0-250V/10A Max. load capacity of normally closed port: DC 0-28V/10A, AC 0-125V/10A Note: No retail package. Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
