Colour:green Material:metal<br><br>after the 220V is connected, the output voltage is delivered to the load immediately, and the load power is broken when the delay arrives. Direct power input, direct 220V output. External power line, load, button can work. Easy to use. Adopt high quality original loose relay, switch current up to 10A. It is equipped with normally open and normally closed points and can be connected as required. The length of time adjustment is adjustable continuously. One second to 60 seconds. The main control adopts NE555 monostable circuit, and the time delay is accurate. Control part of power supply adopts RC step-down, capacitor adopts X2 capacitor according to safety regulation, step-down resistor adopts 3W high-power resistor, filter capacitor up to 470uF, to ensure stable and reliable power supply. FR-4 glass fiber sheet is used to meet the requirement of city electricity, and it is difficult to generate leakage arc. Be able to adapt to all kinds of environment and temperature in electrical appliance. Board size: 65x38 mm, with 4 mounting holes. Input: 220V Output: 220V peak current 10A (maximum 2200W) This module uses RC step-down, debugging and installation, please pay attention to safety, installed in the product should pay attention to creepage distance requirements, to prevent electric shock damage.<br><br>Package Contents: 1 X 220V relay board<br><br>Only the above package content, other products are not included.
