It has been used in various well-known electricity meter enterprises for many years, with stable performance and accurate measurement.
Today, I would like to share with you what series of Sanhe electrolytic capacitor are commonly used in the ammeter industry? What are the characteristics of each?
We all know that the main functions of capacitance in the circuit are: filtering, bypass, coordination, coupling, charging and discharging, etc. The application of Aluminium electrolytic capacitor in the ammeter industry is mainly based on filtering. To select a electrolytic capacitor suitable for the ammeter industry, it must have the following characteristics:
The first characteristic is: long lifespan, with a service life of 5000 to 10000 hours at 105 ℃. For example, the WF series ML series can meet the requirements of
第2個特點是：寬溫度范圍，東北地區溫度較低，即使是在-40℃ -55℃ 都能正常運行；比如RD系列
The second characteristic is: a wide temperature range, with lower temperatures in the Northeast region, which can operate normally even at -40 ℃ -55 ℃; For example, the RD series
The third characteristic is: high frequency and low impedance, which is to ensure that the meter can operate smoothly and have low power consumption. For example, WL series ML WF series
The third characteristic is: high ripple, long lifespan, and high voltage resistance, such as the MT series, with a lifespan of over 16 years
