Power Meter Transmitter VU Meter Head Radio Station

Power Meter Transmitter VU Meter Head Radio Station Description

Movable part: Movable coil type
Pointer swing direction: From left to right
Pointer length: 49 1mm, from the needle end to the
Pointer width: 0.45 0.05 mm
Enameled wire material: UEW polyurethane copper wire

The meter placement position: Vertical
Wire: 2 X 200mm#28 wires, one black and one red. They are used to solder LED positive/negative poles. of the wire needs 5mm of copper to be exposed for easy soldering.
Backlight type 1: Two LED are connected in series "6V, 20mA", connected to a resistor, 620ohm1/2W
Type 2: Two LED in series "6V, 20mA", connect a resistor, 1.3Kohm1/2W
Electrical performance:
Standard test conditions: Temperature 20 degree, humidity 70%.
If there is no difference in the test results, it can also be carried out in a normal temperature and humidity environment.
1 Current sensitivity: The direct current required for the pointer to be at the zero scale to the position shown on the scale plate.
2 Maximum current sensitivity: 200uA 8% of the DC current required by the pointer at the zero scale to the full scale position of the scale.
3 Internal DC impedance: 750ohm 8%.
4 Insulation resistance: test its insulation value with a 500V DC voltage, and the insulation resistance between the meter casing and the electrical circuit is above 50Mohm.
5 Friction: After adding the sensitivity current to the meter, it is slowly reduced to zero. The error between the pointer indication position and the zero scale center is 1mm.
Colour:As Shown
