DC configuration module/intermittent power supply switch module/DC5V-15V/load current 3A-4A

This is a intermittent power supply module revised by the timing restart module. Fan automatically used for power equipment for automatic heat dissipation or miniature fountain, oxygen pump intermittent power supply, which can increase the life of oxygen pumps and reduce electrical energy loss. Note that oxygen pump refers to small fish tanks for small fish tanks for small fish tanks.Oxygers are not industrial or medical equipment, please be careful not to use mistakes!

Regarding working voltage: This product is the range of DC4-15V. It is recommended to enter 5V or more. The chip breakdown voltage is greater than 17V. The input power supply requires stable and extremely low interference. Otherwise, it will affect the stability of the timing module. The rated load current willIt is 3A-4A. When the environmental temperature is used, it can be used by 4A when the environmental temperature is not high. Instantly load current is 5-6A, it can withstand a few seconds. If the load time is less than 1 second, you can bear the current impact of about 10A.Of course, before talking about current, you need to determine how large your wire can withstand the current. If you can't withstand a large current, or change the thick wire or not to connect to a large power load!

Regarding product work mode: There are two working modes of this product, namely 1: 1 interval mode and 1: 2 interval mode, wherein the 1: 1 mode = boot XX seconds to stop XX seconds, the boot and stop time are the same, the 1: 2 mode mode, the 1: 2 modeIt is the XX*0.5 seconds to stop the XX seconds. The stop time is twice as large as the boot time. The time parameters can be selected through the jump line on the back of the motherboard. The default is the 1: 1 mode.In this process, if the D jump line on the back of the short -circuit motherboard will be changed to power to stop for 1 second, and then repeat this process!

Regarding time setting: 1 second, 3 seconds, 6 seconds, 9 seconds, 12 seconds, 15 seconds, 18 seconds, 21 seconds, wait for the boot time to be set to 1: 1 or 1: 2

Regarding the input power supply: This product requires a pure and stable power supply as the input. If your power supply is interfered, please reserve an electrolytic capacitance at the input terminal to filter the interference.Just, if the interference is very heavy, you need to connect a few thousand micro -method to solve the interference. If the interference is not large, try to use a small capacitor with a small capacity!Tip: The starting voltage of the timing module is 3.5-4V, the working voltage is 5-15V, the valuable value of the underwriting voltage is 3V-3.5V, and the module automatically disconnects the load when the input voltage is lower than 3V-3.5V!

If the user wants to change the working voltage, you can replace the 1206 202 resistor in the lower left corner of the motherboard. When the 102 resistance is replaced, the input voltage range is 4-9V, and the range of the 201 resistance is 3-5V.

Input parameters: Starting voltage DC3.5-4V, operating voltage DC5V-15V, with anti-connection protection output parameter: rated current 3A-4A (several seconds to 5-6A) output without short circuit protection

End weld interface

Bring work indicator

Integrated wave protection

Enter anti -connection protection

Load abnormal detection

Two -off time can be adjusted

Owish pressure protection

Enter DC4V-15V (upper limit 16V) IC breakdown voltage 17-18V This product has integrated surge protection function, which can support the use of hot plugging environment

The system is running status LED (lighting out of light, abnormal flashing)

When the load is abnormal, the LED will flicker quickly 2 times per second

Motherboard empty load power consumption: 0.5mA-5MA, average about 1mA

Tip: Input power supply type supports switching power supply or various battery packs. If you connect to power generation input or industrial frequency power supply, please add filter or use other methods to solve the power interference before using it. Otherwise, the default version of the work may be unstable:Working voltage DC4-15V, current: 3A Term Time: 1S/3S/6S/9S/12S/15S/18S/21S (default 1: 1 interval) can also be adjusted to 1: 2, for example1 second, 3 seconds to break and 6 seconds, etc.

Tip: The input power type of the motherboard supports switching power supply or various battery packs. If you connect to power generation input or industrial frequency power supply, please add a filter or use other methods to solve the power interference before using it. Otherwise, the work may not be stable.Remember

A = 3 seconds, B = 6 seconds, C = 12 seconds, d = setting the interrupt ratio, default 1: 1. 1: 2, the default parameter when the factory is left, 1 second, 1 second, if the short circuit D jumps,Line, the ratio is 1: 2, that is, for half a second, break the settings at other times

A = 3 seconds, ignore D pass and break 3 seconds in 3 seconds, set the D jump line for 1.5 seconds to break 3 seconds to ignore the D pass 6 seconds and 6 seconds, when set the D jump line = 3 seconds to break 6 seconds B =6 seconds, A+B = 9 seconds, when ignored D, 9 seconds break 9 seconds, when set D = pass 4.5 seconds to break 9 seconds

C = 12 seconds, ignore D Tong Tong for 12 seconds and 12 seconds, set D pass for 12 seconds for 12 seconds A+C = 15 seconds, ignore the D pass for 15 seconds for 15 seconds, set D pass 7.5 seconds to break 15 seconds B+C = 18 seconds, ignore the D pass for 18 seconds to break 18 seconds, and break 18 seconds in 9 seconds when the D pass is set

ABC = 21 seconds, when the D jump line is ignored, the D -jump line is set for 21 seconds, and the D jump line is set for 21 seconds.Blind protection and load abnormal detection, quickly flicker when abnormal!
