Product description
This is a modified version of the timer restart module intermittent power supply module for power equipment fan automatic cooling or miniature fountains, oxygen pumps intermittent power supply, you can improve the life of the oxygen pump to reduce power loss, note that the oxygen pump refers to small fish tanks with the oxygenator is not an industrial or medical equipment, please pay attention to Do not make a mistake use!
On the operating voltage: This product is DC4-15V range, it is recommended that the input 5V or more, the chip breakdown voltage is greater than 17V breakdown, the input power supply needs to be stable and low interference, otherwise it will affect the stability of the timing module, the rated load current is 3A-4A, depending on the ambient temperature to use the ambient temperature is not high can be used to 4A, the instantaneous load current resistance of 5-6A can withstand a few seconds, if the load time is less than 1 second, if the load time is less than 1 second, please note that do not make a mistake! If the load time is less than 1 second, it can withstand a current shock of about 10A, of course, before talking about the current, you need to determine how much current your wire can withstand, if you can not withstand high current, either change the thick line, or do not connect the high-power load!
About the product working mode: this product has two working modes, respectively, 1:1 intermittent mode and 1:2 intermittent mode, where 1:1 mode = power on xx seconds stop xx seconds, power on and stop time is the same, 1:2 mode is power on xx * 0.5 seconds stop xx seconds, the stop time is twice as long as the power on time, the time parameter can be selected through the jumper on the back of the motherboard, the default is 1:1 mode, the default is 1:1 mode, the power on is 1 second. The default is 1:1 mode, after power on, it is power on for 1 second, stop for 1 second, then repeat the process, if it is short-circuit the D jumper on the back of the motherboard, the operation mode will be changed to power on for 0.5 second, stop for 1 second, then repeat the process!
About the time setting range: 1 second, 3 seconds, 6 seconds, 9 seconds, 12 seconds, 15 seconds, 18 seconds, 21 seconds, and so on 8 combinations, boot time can be set to 1:1 or 1:2
About input power: this product needs pure and stable power supply as input, if your power supply has interference, please reserve a port at the input side and connect an electrolytic capacitor to filter the interference, if the interference is very small, connect a few hundred microfarads of capacitors on the line, if the interference is very heavy, then you need to connect thousands of microfarads of capacitors in order to solve the interference, if the interference is not too big, try to use a small capacitor it! Tips: Timing module startup voltage 3.5-4V, working voltage 5-15V, undervoltage protection threshold 3V-3.5V, input voltage below 3V-3.5V module automatically disconnect the load!
If users want to change the operating voltage, you can replace the 1206 202 resistor on the lower left corner of the motherboard, replace the 102 resistor, the input voltage range is 4-9V, replace the 201 resistor range is 3-5V.
Input parameters: starting voltage DC3.5-4V, working voltage DC5V-15V, with reverse connection protection Output parameters: rated current 3A-4A (a few seconds to 5-6A) output without short circuit protection
Welded wire interface at both ends
Integrated surge protection
Input reverse connection protection
Input DC4V-15V (upper limit 16V) IC breakdown voltage 17-18V This product has integrated surge protection function, can support hot plugging environment.
System operation status LED (on and off, abnormal blinking)
When the load is abnormal, the LED will blink rapidly 2 times per second.
No-load power consumption of the motherboard: 0.5mA-5mA, about 1mA on average.
Tip: Input power type support switching power supply or various types of battery packs, if you are connected to power generation class input or industrial frequency power supply, please add their own filter or use other methods to solve the power supply interference before use, otherwise it may not work stably Default version: operating voltage DC4-15V, current: 3A within the on-off time: 1S / 3S / 6S / 9S / 12S / 15S / 18S / 21S (Default 1:1 intermittent) can also be adjusted to 1:2 intermittent, such as through 0.5 seconds off 1 second, through 3 seconds off 6 seconds and so on.
Tip: The input power type of the motherboard to support switching power supply or various types of battery packs, if you are connected to the power class input or industrial frequency power supply, please add their own filter or use other methods to solve the problem of power interference before use, otherwise it may not work stably, remember to remember!
A = 3 seconds, B = 6 seconds, C = 12 seconds, D = set through the ratio, the default 1:1, set to 1:2, the factory default parameter is through 1 second off 1 second, if short-circuit D jumper, then the ratio of 1:2, that is,: through half a second off 1 second, the other time to superimpose settings
A=3 seconds, ignore D when pass 3 seconds break 3 seconds, set D jumper when pass 1.5 seconds break 3 seconds ignore D when pass 6 seconds break 6 seconds, set D jumper = pass 3 seconds break 6 seconds B=6 seconds, A+B=9 seconds, ignore D when pass 9 seconds break 9 seconds, set D = pass 4.5 seconds break 9 seconds
C=12 seconds, ignore D time on 12 seconds break 12 seconds, set D time on 6 seconds break 12 seconds A+C=15 seconds, ignore D time on 15 seconds break 15 seconds, set D time on 7.5 seconds break 15 seconds B+C=18 seconds, ignore D time on 18 seconds break 18 seconds, set D time on 9 seconds break 18 seconds
ABC=21 seconds, ignore D jumper, pass 21 seconds, break 21 seconds set D jumper, pass 10.5 seconds break 21 seconds, since the power on start timing, LED with the pass off light or off, the chip comes with under-voltage protection and load anomaly detection, abnormal fast blinking!
9, the probe can be plugged and unplugged design, convenient for testing.
For ozone gas detection devices in domestic and atmospheric environments.
