Description

ZMDS***1 single phase electronic kWh meters adopts special Large-scale integration circuit, has the characteristics of few peripheral elements, simple structure, high reliability, low powerloss, long life-span, which is the single phase AC power electric meter and the reference frequency is *0 Hz. The meter can be installed indoor or outdoor, adapt to the environment temperature is **0℃~**0℃, relative humidity is less than *0%. All the capability and specification is in accordance with all the technical requirements of ANSI*2.1 standards, especially for single phase electronic meter. Function and characteristics Adopting special LSI and SMT surface installation technique, advanced craft work, simplestructure. Using the latest electric integrate circuit compacted with inner digital multiplier, greatly improve the dynamic working range, enlarge the over loading capability several times more. All the elements of the meter is ling life-span and highly reliable. Precise unidirectional measurement of the active energy, ling service time without callbration. Impulse output indicating when the meter is working. Expandable infrared communication or RS***5 communication function. High Electro-Magnetic Compatibility, and anti-tampering function with LED indicator. Adopting Mechanism register to display the KWh clearly and straightly; step-upon electric motor with shielding cover, good anti-jamming capability; LCD displaying module is selective. Good Measurement characteristic, working under the condition of variety of power factor all complied with flat and suitable load curve. Low power loss designing, power loss is not more than 1W. Wide voltage range designing, make sure the meter can work normally between 0.7UN~1.2UN.
