The board belongs to high frequency square AC output; it is not suitable for the inductive appliance, such as motor, fan and coil transformer. 2. While picked up with low-load machines (LED light, mobile phone charger and DVD set-top box), you are suggested to pick up with low voltage point, such as: 172V/110V. 3. You should install a large heat sink to release its long time high-load (¡Y100W) work. 4. You could not connect the power inversely. Besides, power supply and power wire should have large enough current. 5. Do not overload and short-circuit because it without any protections. 6. The number in measured by the output high frequency non-load voltage meter will be a little higher.   Output wiring the following voltages:   V0--V2=110V V0--V3=175V V0--V4=200V V0--V5=220V V5--V4=20V V5--V3=45V V5--V2=110V V4--V3=28V V4--V2=90V V3--V2=62V Package includes: 1 x 150W Converter DC 12V to AC 220V Inverter

Features:   - The product delay time can be set by yourself, and can be set by the button. After setting, it will count down according to the set value after the next power-on. - The product is accurate delay, 0.01% error per second. This product has three delay versions. One version has a delay of 0-999 seconds, and the LED changes every 1 second. The other delay time is 0-999 minutes. The LED digital display changes every 1 minute; the third version has a delay of 0-999 hours, and the hourly LED digital display changes; - Can be triggered by an external signal. When power is on, the power LED lights up, but the module does not work. When there is an external trigger (low power or high level trigger) (such as the button is grounded instantaneously), the relay is triggered, the module starts to work and countdown delay, when the delay time After the relay is disconnected . If during the delay process, it is triggered again, the delay time starts counting again, and the delay time has been triggered last time. - This product has a wide range of applications and can be used in many fields. The new version can be easily used in equipment such as car driving recorders!   Specifications:   Voltage: input voltage 5-24V (higher than 15V need to be used for heat dissipation) Current: less than or equal to 100mA Load: 250V 10A AC or 30V 10A DC Power consumption: 0.5W Delay range: 0-999 hours or 0-999 seconds or 0-999 minutes Size: 55.8mmx34mm   Adjustment Method:   1. The first time the power is turned on, the system defaults to the initial value of 10 seconds (minutes) countdown. 2. Time setting: The left button is the LED bit digital adjustment, which increases from 0-9 cycles; the right button is the LED bit selection button. Specific method: After power-on, press and hold the left button. After about 3-5 seconds, the third digit of the LED starts to flash. At this time, you can continue to press the left button or the right button. Press the left button. The corresponding flashing digit of the LED can be from 0-9. Change, if you press the right button, the LED bit is selected. When a bit is selected, the corresponding bit will flash. After the 3 digits of the corresponding LED are all set, wait for about 3-5 seconds, the system will automatically save the time set at this time, and wait for the next time to start the countdown delay according to the set value! 3. Power on again, start working properly according to the set value!   Package Included:   1 x 24V Trigger Time Delay Relay Module 0-999s 0-999min 0-999H Work-delay/Delay-work
