Description:
- 100% brand new and high quality.
- Features:
This is a DIY kits,need buyer to assemble it.
Power display is to take some voltage, perform simulations show the percentage
of segments, such as 3.7V lithium battery, take the lower voltage 3V, the upper
limit of 4.2V, 4.2-3 = 1.2V, the voltage difference between the lower limit of
1.2V, is the battery Analog power up
LM3914 can accurately detect an analog voltage, and 10 LED display, display dot
mode LED is lit 10 one, or in a stripe pattern individually lit LED
Display Description: Displays the battery voltage between the lower limit of 10
files showed that representatives of each of the lights 10% charge displays, on
behalf of 10 lights display charge 0% -100% range; you can also change the
single light display, is displayed only a light, more power, single-light power
4mA, all bright 42mA
A variety of high and low voltage battery display range adjustment:
1. Lithium battery:
After the completion of a single lithium battery discharge voltage is 3V, when
fully charged 4.2V;
1S correspond to 3V (first light) to 4.2V (tenth lights);
2S corresponds to 6V (first light) to 8.4V (tenth lights);
3S correspond to 9V (first light) to 12.6V (tenth lights);
4S correspond to 12V (first light) to 16.8V (tenth lights);
Other series voltage and so on.
2. Lead Acid Batteries
6V or 12V lead-acid battery is generally:
6V corresponds to 4.8V (first red light) to 6.75V (tenth lights);
12V corresponds to 9.6V (first red light) to 13.5V (tenth lights);
The module according to the above standard battery discharge range design, can
accurately reflect the battery, so that users can readily observe the status of
the battery.
Adjustment of the following methods:
Equipment needed: an adjustable power supply, precision accuracy of the
decisions of the panel display. Watches word screwdriver.
Case in single 3.7V lithium, 3V is less low-end power, 4.2V for the full power
of high-end.
1, the adjustable power supply voltage to the desired voltage display high 4.2v,
connect this board, this time there are two results: one is not bright, one is
all bright or light a few. This time slow adjustment plate 503 (50k)
potentiometer until the LED strip just lit up the whole. Several light does not
shine or counterclockwise to adjust, when full light clockwise.
2, the adjustable power supply voltage to the low end of the desired 3V.
Adjustment board 502 (5K) potentiometer to just light a LED, does not light
clockwise adjustment, several or all bright light counterclockwise.
3, patiently repeating the first step two. Usually 2 times to adjust to the
desired display range.
Display Mode A / P: full brightness linear / single lamp lattice mode switch,
the default is a linear model, the board set aside a switch pad, even with
soldering pads can be turned into full light linear mode, no welding is the
point like single light display
Note:
To adjust their voltage, according to the method of adjusting the order, to
emphasize high-end, then adjust the low end.Red then positive, then negative
black, must not be reversed, this module is the maximum limit voltage DC 20V,
please use anti-static welding or soldering station pull electric heat welding
Specifications:
Power: bar display full brightness 42mA, single light shows 4mA
Measuring range: the battery inside the common 2.4-20v
Light Color: Red/Green/Blue
Display: Multi-light bar display or a single light dot display
Suitable for lithium batteries, lead-acid batteries and other power batteries
need to be displayed
Power adjustable display range for the battery discharge curve of a scientific
setting, direct support: single lithium 1S (4.2V) ~ 4S (16.8V), lead acid 6V ~
12V, NiMH 3.6V ~ 18V, nickel-cadmium batteries 3.6V ~ 18V
Size: 4.5x1.9cm/1.77x0.75inch
Quantity: 1 Pc
- Note:
- 1.Please allow 1-2cm error due to
manual measurement. pls make sure you do not mind before you bid.
