LB1415
LB1415 is Level Meter manufactured by SANYO.
Features
(1) 2 types of LB1405/1415 available depending on parator. ( 2 ) Bar-shaped display of input level with 5 LEDs (see right.) (3) Built-in LED direct drive output of constant current that supply voltage regulation causes no variation of LED current.
(4) Wide remended supply voltage range : 4.4 to 12.0 V
