Application
ZMDS4501 single phase electronic kWh meters adopts special Large-scale integration circuit has the characteristics of few peripheral elements, simple structure, high reliability, low power loss, long life-span, which is the single phase AC power electric meter and the reference frequency is 60 Hz.
The meter can be installed indoor or outdoor, adapt to the environment temperature is -10℃~+60℃, relative humidity is less than 80%. All the capability and specification is in accordance with all the technical requirements of ANSI12.1 standards, especially for single phase electronic meter.
Function and characteristics
Adopting special LSI and SMT surface installation technique, advanced craft work, simple structure. 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-485 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.The meter cover and base is made of Bakelite , PC, ABS etc., in accordance with Type insulation protection requirements, good anti-fire and insulation capability, firm structure and nice appearance.
Working principle and structure:
Working principle:
ZMDS4501 single phase electronic kWh meters adopts special Large-scale integration circuit to measure the KWh(Indicated by the broken line of the picture). The measurement of the Kwh consumed by the users, through the sampling of the signal by the voltage separator circuit and the shunt, processing the A/D converting procedure, the digital signal which is processed by the multiplier would be sent to the D/F converter, the impulse which is output by the converter circuit would drive the register to get the accumulated KWh, display the electricity consumption velocity by the KWh indicator.
Structure:
The meter shell is composed of meter base, holder and transparent cover, Lead sealing is put between the cover and the base The appearance of the register displaying type
