| Three-phase electronic watt-hour meter Type：LTM34 Product number：LTM34－2a Weight：1.35kg ☆ Product Brief introduction This three-phase electronic watt-hour meter
adopts advanced microelectronics technique and SMT manufacturing
technology. Its performance conforms to IEC 61036 Standard, whose
rated frequency is 50Hz or 60Hz. The meter own the function of
forward direction ,reverse direction electric quantity
metering respectively or active forward and reverse direction power
accumulation metering ,which is optional. The meter with
characteristics of LCD displaying means or step-register with
circular type. Also owns the advantage of measuring accuracy high,
the sensitivity high, the power loss low, the load width, the
volume small, the weight light and so on the characteristics, The
electric quantity could add optical port or RS485 and RS232
communication, which is accorded with IEC 62056-21 or IEC 1107
requirement. ☆ Function and Features 1. Owning forward and reverse direction metering
function, besides, it can accumulate electric quantity in one same
direction (optional) 2. Adopt LCD displaying, of which there are 5
integers and one decimal-place (could increase the display number) 3. If lack of phase, it could be display 4. Own passive electric energy impulse output
terminal, the impulse output is square wave, and the impulse width
is 80ms 5 .there are LED which proportion with the
energy output in the panel for the purpose of calibration. 6 .adopt transparent cover, which made of
self-extinguishing ABS material, and the connecting terminal made
of bakelite, IP54, which designed are waterproof and dustproof 7. High metering precision, high sensitivity,
low power consumption, wide load, small volume, light weight etc. ☆ Technical parameter 1. Accuracy：class 0.5, class1.0； 2. Rated voltage：3×120/208V or 3×230/400V； 3. Rated Frequency： 50Hz/60Hz； 4. working temperature：-25℃~+60℃； 5. Store temperature：-30℃~+70℃； 6. Impulse voltage：6kV 1.2/5ous； 7. Current circuit：0.3VA； 8. Voltage circuit：0.8W/3.5VA； 9.
