Single-phase
fee control smart watt-hour meter, used to measure the rated frequency
of 50Hz AC single-phase active energy, to achieve first pay after the
power management functions.
This product is manufactured
by special VLSI and SMT process. The key components and components
adopt well-known brand of low power consumption and long life device.
The whole machine adopts a variety of anti-interference technology to
improve the reliability and service life of the product. , The data show that using large-screen Chinese LCD, easy to meter reading.
This
product can directly measure the positive and negative active energy
accurately and directly, and make multi-rate measurement according to
the corresponding rate setting, which can store the total energy and the
energy data of each rate on the 12 settlement days. With event logging. Support 2 year time zone, 2 day timetable, 8 day time, 4 kinds of rates. At
the same time also has infrared and RS485 communication, remote meter
reading can be achieved, communication protocol to follow DL /
T645-2007. Its performance indicators in line with GB / T 17215.321-2008 and GB / T18460.3-2001 standards.
The meter test output does not produce more than one pulse when the meter is applying 115% of the reference voltage without current in the current line.
Watt-hour meter in the factory after passing the test, and seal, you can install and use.
installation
Meter should be installed indoors. The
upper part of the power meter base has a hook screw hole, which can be
fixed with a hooking screw; two mounting holes are arranged at the lower
part of the energy meter and can be fixed with screws on the wiring
board; the bottom plate of the energy meter should be placed on a solid
and fireproof wall; About 1.8 meters. Meter installation location as shown below:
