Professional Smart Single Phase Electric Meter Active Energy
Measuring ANSI Meter
Description:
The Wuhan Radarking has the most advanced single phase electronic
watt hour meter that uses large integrated circuits. It uses
digital sampling and SMT technique which is suitable for measuring
active energy in electric net with single phase Alternating Current
50Hz or 60Hz. A Liquid Crystal Display(LCD) is used for the
register. Then meter must be mounted on a location with temperature
range of -25C to +55C and relative humidity not exceeding 95%. The
air should be free of harmful gases, dust, mildew, insect, etc.

Function:
1) Measurements
* Energy (kWh) and Active Power (kW)
* Delivered only
* Received only
* Delivered + Received
* Delivered - Received
* Energy (kvarh) in two ways: Delivered and Received (LCD only)
* Instantaneous values: voltage, current, frequency, temperature
etc (LCD only)
2) LCD Display
* Display of Energy configurable to 4, 5 or 6 digits
* Energy and instantaneous power are displayed on LCD
* Three display modes:
* Normal, display energy and instantaneous power
* Alternate, display all measurement items
* Frozen, display error and caution inner meter
3) AMR (optional)
* Two UART port:
* One is used to work with 3rd party suppliers of communication
systems to integrate AMR technology
* The other is optical port, local read by handset
* Compliant ANSI C12.18 and ANSI C12.19.
* MeterBuddy software
* Read the state information and data from meter.
* Set or change sag and thresholds.
* Perform a master reset to clear energy values; voltage event and
power fail record.
* Obtain a meter program and data summary report.
4) Load Control (optional)
* Remote connect and disconnect
* Auto disconnect logic
* Supply capacity limit
* Emergency Supply capacity limit
* Active power limit
Features & Benefits:
1) High reliability
2) Low starting watts
3) Low burden
4) Anti-tamper design
The LIBRA-1 meters' anti-tamper features include measuring energy
even if the meter is inverted and detecting when the meter is
removed from a live socket.
5) Large easy to read LCD display (or Cyclometer optional)
6) Nocturnal visibility
When the environment low light, the LCD backlight automatically
open.
7) Battery (optional)
Offers a cover battery port enabling changing of the meter battery
without removing the meter inner-cover.
8) Remote Disconnect (optional, 200A max)
9) Network Applications
Ready for an automatic meter reading (AMR) system. Several options
are available for network communication technologies, various PLC
and RF modules.
10) Four options for Energy Accumulation
Delivered only, Delivered + Received, Delivered - Received,
Received only
11) Functionality modularized architecture
Allows new snap-in specific modules to be installed into the meter
without disturbing the finely calibrated measurement function.
Optional snap-in modules include demand, time-of-use (TOU), load
profile and various communication protocol options.
12) ANSI standards compatible
* ANSI C12.1-1995 ANSI C12.10-1997
* ANSI C12.18-1996 ANSI C12.19-1997
* ANSI C12.20(Class 0.5)-1998 ANSI C37.90.1-1989
* ANSI C62.45-1992 IEC 61000-4-4
* IEC 61000-4-2 FCC Part 15,Subclass C
