1. Power supply current: 10A2. Power supply voltage: 12v/24v3. Use: Time delay4. Module to achieve a certain time delay after power on and then output voltage / or off output5. Delay time 1~120 seconds adjustable, can be used for car recorder delay on, faucet after the water delay off and other applications6. With power supply reverse protection, reverse connection will not burn7. With repeat trigger button interface, can be connected to a button to achieve re-trigger the delay time, without the need to re-power8. To adjust the delay time: the module is connected to the power supply, using a multimeter voltage class to measure the voltage value of the two points AB, every 0.039V for 1 second. For example, to adjust to 15 seconds, it is 0.039Vx15 = 0.58V, after adjusting the charging power off and then power on test, if the time value meets the requirements, the normal use of the module can be (default factory value of 1 minute)9.
