Description

2pcs TR-57 VU Panel Meters DB Level Header Backlight w 1pc Power Driver Board
Parameters:
Pointers Material:
Nickel silver strips
Pointer color:
black
The direction of the pointer swing : left to right
Pointer length :  30± 1 mm from the center axis to the needle end
Pointer width :  0.45 ± 0.05 mm
Features:
*Standard test conditions temperature: 20 ℃, humidity 70% . Can also be tested under normal temperature and humidity
*The influenza degree pointer at the zero scale to the maximum scale sensitivity of
2.0V ± 10 %
(full scale position) internal impedance :
600Ω ± 10%
*Insulation impedance meter outside the box plus the electrical circuit with 500V DC plus 50M ohm meter shell
*Electrical insulation of the circuit impedance is 500V DC voltage test of the insulation value. Pointer to overlap with the zero-scale tolerance of ± 1mm balanced meter using a standard position and tilt 90 degrees to allow the error range of ± 1mm
*pointer to mount the current instant plus three times the full scale current, and slowly reduced to the the electric influenz degree 1/2 reading,
*The pointer will return to the scale plate within 1/3 scale friction meter coupled with the current, and slowly increase or decrease to a certain value, indicating the point of error range of ± 1mm,brake instantly plus scale plate 2/3 of the current value of the pointer indicates the location of the time required for a second or less.
Driver Parameters:
1. It is a new upgraded version,  replacement of the discontinued TA-7318P IC, works better.
2. Increase the output signal to drive more models of the meter. And can be combined with the expansion circuit to increase the peak PEAK indicator function.
PCB size: 60*39mm
Rated power: 3W
Operating voltage: AC / DC 12-15V
Meter connection cable: half a meter in length, divided into two to use
