Model: JK021 AC power-on delay power-off module (original model JK02-220V)
Function: After connecting to 220V, the voltage is immediately output to the load, and the load is disconnected after the delay arrives. (Note that this power-on starts to delay, no trigger signal is required)
Basic features
Direct mains input, direct 220V output. The external power cord, load, and button work. Easy to use. (If you need the output to be isolated, that is, if you do not have electricity, please contact the store to note JK022)
The high-quality original Songle relay is used to switch the current to 10A. It is equipped with normally open and normally closed points and can be connected as required.
Delay adjustment time length potentiometer is continuously adjustable. 1 second to 60 seconds.
The main control adopts NE555 monostable circuit with accurate delay.
The control part of the power supply adopts RC step-down, the capacitor adopts X2 capacitor conforming to safety regulations, the step-down resistor adopts 3W high-power resistor, and the filter capacitor is up to 470uF, ensuring stable and reliable power supply.
It adopts FR-4 glass fiber board, which is suitable for the mains demand and is not easy to produce leakage electric arc. Can adapt to various environments and temperatures in electrical appliances.
Board size: 65×38 mm with 4 mounting holes.
Input: 220V
Output: 220V current up to 10A (maximum 2200W)
