Rail type digital display meter

Focusing on multiple types of rail mounted digital displays (including NHZ-1P/3P, NA-1P/3P, NVAHz-1P, NDM1-63/100, N52-2042/2066, etc.), the core covers measurement functions such as voltage, current, frequency, power, and electrical energy. Key parameters include measurement range (voltage AC 40V-500V, current AC 0.1A-100A, frequency 0-99Hz, power 0-45000W), accuracy (± 2% or 1% ± 2words), sampling rate (1 time/second or 2 times/second), installation method is 35mm DIN rail installation, suitable for working conditions such as altitude ≤ 2000m, ambient temperature -30 ℃~70 ℃, etc. It is prohibited to use it for frequency converters, inverters, and high-order harmonic interference. In the power environment, some models require the use of current transformers (when the current is greater than 100A).
