LM3914 10 Segment 3.7V Lithium 12V Battery Capacity Indicator unassembled Module Power Level Tester LED Display

Description

Features: 

– This is an assembled kit.

– The power indicator is to assume a voltage, the simulation percentage of segments, such as 3.7V lithium batteries, 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, the battery is analogue. 

– LM3914 can accurately detect an analogue voltage, and 10 LED indicator is the display of the display point mode LED 10 one, or in a strip pattern that lights up individually. 

– Display description: shows the battery voltage between the lower limit of 10 files, indicating that representatives of each of the charge indicators of lights 10% charge indicators, on order of 10 light display charge 0% -100% -Arrange; you can also change the single light display, only be a lighter, more power supply, storage. current 4 mAAll bright 42 mA displayed. 

– Suitable for lithium batteries, lead-acid batteries and other power batteries must be displayed. 

– Power adjustable display range for the battery output 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. 

Parameters: 

Power: bar display full brightness 42mA, single light shows 4mA 

Measuring range: the battery within the common 2.4-20V 

Colour: red, green, blue. 

Display: multi-light bar display or single light box display 

PCB card size: 45 x 14 mm 

Display mode A/P: full brightness linear / single lamp grid mode switch, the standard is a linear model, whereby the board sets a switch pad aside, even with solder pads can be converted into linear mode in full light, no welding of the point, single light indicator. 

A variety of high and low voltage battery indicators.

Package: 1 PCs assembled module
