Detailed Product Description

Product Brief Introduction

LTM-G Series Single Phase socket type two wire and three wire compact

watt meter

The single-phase plug type electrical energy table uses the newest craft

manufacture, has the volume to be smaller, the weight is lighter, the

service life is longer and so on the characteristics, this instrument

quantity is accurate, the performance is reliable, conforms to ANSIC12.10

and the IEC62053-21,IEC 62052-11 standing operating procedure 1.0 level of

electrical energy measurement request, uses the LCD demonstration electric

quantity (also to be possible to select register demonstration electric

quantity).The watch cover uses being flame-resistant to gather the carbon

manufacture, it has the dual insulations, IP53 dustproof, the

waterproofing, shows the base to make by the high grade bakelite material.

The communication conforms to the IEC1107 communication agreement, the

electrical energy table has the photoelectric communication port, the user

may carry on the electric instrument parameter through this photoelectric

communication mouth the establishment or the downloading data recording, in

sets at RS-485 or the RS232 port, only can use the corresponding on

position machine system software to carry on the read-write operation, this

table may the record reverse electrical energy (be possible folk remedy to

measurement electrical energy).

Product Features
* Single and Multi-rate options
* Optical IEC 1107 Flag Port (optional)
* Active Energy and Maximum Demand (optional) measurement
* Reverse Energy Register (separately record or add to forward register as

required)
* Fraud Protection
* Compact size and weight .
*Display remains operative in the event of supply failure (optional)

1. Product Highlights
This meter can be supplied with a large digit LCD or a Cyclometer

Register.  The use of innovative metering technology provides high

security and ensures the meter maintains its accuracy over its full

operating range.
2. Meter Case
Meter cover is made of self-extinguishing recyclable polycarbonate.It has

double insulation and has IP53 protection against dust and water

penetration.  The meter base is made of high quality bakelite.
3. LED Indicator
A high light LED is mounted on the front of the meter, pulsing at a rate

proportional to the measured load. The pulse  is identified on the meter

cover. The pulse can be used for checking calibration of the meter.
4. Communication
The meter has an optical interface based upon IEC 1107 protocol. The user

can program meter parameters or download recording data through this optic

port. Optional built-in RS-485 or RS-232 port for accessing to AMR system.
5. Reverse Energy
Reverse Energy is detected if export energy greater than the meters

starting threshold is measured. If reverse energy is detected, the alarm

flag will display on the LCD.  The meter will register the reverse

enenergy. (Unidirectional meter measuring energy).
