มิเตอร์วัดกระแสไฟฟ้าหลายช่องทางสามเฟส

1. Main features
A. High accuracy: With full electronic design, import specialized energy-metering chip, high sensitivity, exact measurement; Accuracy is not influenced by frequency, temperature, voltage and high harmonics. The complete meter is not calibrated again after leaving factory.
B. High quality: Adopt SMT manufacturing processes and select international well-known brands, long life-cycle components to make sure the stable quality.
C. Lower power dissipation: The most optimized design to make power dissipaton be less than 2.5W. When used under wide range, the meter can reduce the power grid dissipaton and also improve effeciency of power supply.
D. Stable running: With good capability of anti-interference, strong capability of over-load and wide operating voltage, etc. All of these features can ensure higher stablity.
E. Data display: Display accumulative power consumption and running status of all period of time and tariffs.
F. Data security: LCD displays various power consumption data and meter's status clearly and brightly.
G. When power off, internal data can be remained for 10 years; Meter uses lithium battery as clock's back up power supply to ensure normal work for it.

2. Applicable scope
The meter is applied to three-phase enterprises with prepayment and multi-tariff functions. This meter can solve the collection of electricity charge, and realize time-shared measurement, automatized management and external functions as per local power utility's management needs. It is the ideal meter for power utility to effeciently control and adjust grid load.
