Analog meters FeaturesEs
This series products have electromagnetic and magneto electric two types, which is applied for control system or power distribution

system to display the corresponding electrical parameters, such as AC/DC current, AC/DC voltage, power factor, Hz, etc.

Analog metersStructure Characters
Magneto electric Type: Basic operating mechanism is inner magnetic structure. AC current/voltage meter is made by subjoining

thyristor rectifier circuit on DC pointer of inner magnetic structure. Because the rectifier circuit and measuring mechanism separate

out, it is easy to maintain.
Electromagnetic Type: It includes meter shell, dial, coil, bracket, fixed core component, moving-iron, pointer and hairspring, which

has good overload capacity and low cost.
The meter cover and the meter body adopt crystalline synthetic glass and black plastic respectively.
