DC 0~100V 3~Wire LED 0.56in Dial Voltage Meter Panel

Descrtion:1.This s 0.56inch LED dial tube and partially closed ABS plastic casing without rear cover.2.The is r thin with small shape and low price and stable performances. It can display well.3.This 's measurement range is wide，it's DC0-100V.4.It need outer working power supply and the voltage is DC4.5-30V.5.There is protection when the wires aren’t correctly connected.6.This 's display resolution is 0.1V.7.This is suitable for clients who has DC power supply，beca this can save cost. And it can be d when the voltage need to be measured from 0V.Feature:With 3 wires, easy connection; anti-impact shell, dust free pt producing; rior ;No ex power supply is needed for DC4.5- 30V voltage;High precision, low starting working voltage; with re protection, prevent ing wires; fine adjustment function;Specifications:Measuring range: DC0-100VThe highest input: DC120V (risk of ing above this voltage)Allowable error: ±1%Display mode: three 0.56′′ LED dial tubesDisplay Color: Red/Green/Blue (optional)Refresh rate: about 200mS/timesPower supply: DC4.5-30VCurrent consumption: le than 20mA, generally 5-15mAWorking temperature: -10°C~65°CDimensions: 48mm x 29mm x 16mm / 1.89in x 1.14in x 0.63in (Length x Width x Thickne)Opening size: 46x27mmLead length: 20cmPrecautions1.This 's measurement range is 0-100V，this voltage is just measurement signal and it can't be regarded as 's working power supply. This need outer working power supply which can supply DC4.5-30V as working power supply. About three wires，the blawire is communal negative pole，the wire is connected to measuring voltage's positive pole，the red wire is connect to working power supply's positive pole，the measuring circuit and power circuit's negative pole are communal.2.The voltage of this 's working power supply is 4.5-30V，30V is the ’s maximum operating limited voltage，please leave enough margin when working，to avoid ’s permanent damage beca of electrical spark，power supply rple，or other too high abrupt change of voltage.3.This didn’t do moisture-proof,waterproof,shockproof,anti-oil proceing,please be careful or handle by yours when using.Package include:1 x DC100V
