Government bidding for supporting multifunctional power instruments and power systems

A key project of Xiamen Siming District Government has chosen our company's multifunctional power instrument power system. The following is the on-site scene after successful installation:

The development of this system has 5 major features:

1. This setIn addition to industrial grade varistors for power withstand protection, the power input terminal of the multifunctional power instrument is also equipped with a self recovering fast fuse produced by Tyco Electronics in the United States for power surge protection, ensuring stable use of the multifunctional power instrument.

2. Johnson Intelligent Multi functional Power Meter adopts switch mode power supply, wide voltage AC/DC universal, and adds high-voltage capacitors and supply mode inductors at the power input end to filter out harmonic interference to the power grid, which meets EMC electromagnetic compatibility requirements.

3. All electronic components such as resistors and capacitors are made of pure imported products (such as Murata from Japan, Black Diamond from Japan, Guoju, etc.), and are made of fully automatic imported lead-free and environmentally friendly solder patches.

4. The sampling current transformer adopts high-precision specialized electrical measurement transformer, made of flame-retardant PBT material, and the wire adopts multi strand flame-retardant soft copper wire, with a flame-retardant rating of level one.

5. The Johnson Intelligent Multi functional Power Meter LED Display Screen adopts a high brightness color screen mold, directly displaying U, V, A, KW, Kvar, PF, Hz, which is intuitive, clear and easy to understand.
