Brand new and high quality OOTDTIC Shorts description one size: 6.8 for cm*2.1 for cm seconds, main chip: NE555 third, working voltage: 12 VCfour Features:1, tensile strength delay relay. In particular: 12V power supply for the relay, the relay is not immediately absorbed, and the status of the relay outputs are: disconnected normally open, normally closed, and public; wait until the delay of 1-10s (adjustable), the suction relay and, in time, the output status relay are: normally open and public driving, Normally closed and public disconnected; While the uninterruptible power supply power module, this state will be maintained. 2, Delay per time is adjustable, (0 to 10 seconds) 4, to increase potential can increase delay to time 5, Increase capacitor C1 can increase delay to time 6, With input power indicator 7, With relay indicator 8, AC 220V/10A can be controlled on the equipment. (Maximum equipment control 2000 for W) 9, with freewheel for protection relay. 10, Formula for with time delay: for T=1.1 rc. For example: capacitor resistance 100uf 100K for T = 1.1*100000*0.0001 = 11 seconds Applications 1, the vehicle delay device is turned on to avoid excess current when the car on the vehicle firing device. 2, It is necessary to start the occasion to avoid multiple devices at the same time, the inrush current is too large devices that burn.
