DDZY1122C-Z Single phase local tariff control smart meter

La description

 Single phase local tariff control smart meter 

【Overview】 Adopting advanced integrated circuit design and manufactured with advanced SMT and re-flow soldering technology, single phase local tariff control smart meter DDZY***2C-Z has the features of accuracy, high overload, low power consumption and strong capability of resisting disturbance. And the meter was equipped with infrared palmtop, RS**5, power line carrier communication connection, which can ensure the customer program, timing and reading the meter by themselves. 
【Function overview】 * Store the latest *2 months active power forward direction overall, peak, smooth, valley electric quantity and active power total electric quantity. 
* Save latest *2 hours null point freeze data and *6 integral point freeze data; save latest 2 time zones, time interval records and appointed freeze record;  save latest 3 instant freeze records.  
* Broadcast timing function: the gap between electric meter clock and timing clock within 5 minutes can broadcast timing; otherwise the electric meter would not response. Broadcast timing can check once per day.  
* Built-in clock chip, multi-tariff, which can support *4 time intervals. 
* Events recording function: record program, timing, reset, open meter cover, power down, switch out, switch on recording. 
* Automatic settling account function: can set the settling account by management system. 
* Freeze function: freeze at fixed time, instant freeze, convention freeze, daily freeze, integral point freeze 
* Tariff control smart: the electric meter has time division electrovalence and stepwise tariff, which can switch over by the setup. 
* Alarm function: set up the alarm amount to remind the user to purchase electricity in time, preventing the unnecessary troublesome to users.  
* Overdraw function: after user consumed the purchased amount but hasn’t purchase more in time, he is allowed to overdraw some amount. 
* Preventing corner function: when the electric meter balance amount is more or equal to the recharge threshold amount, it won’t allow this purchased amount. 
* Remote power on & outage control function. 
* Problem self test function. 
* Battery under voltage test function. 
* Have the auto cycle display status and keypad page turning display status.  
* Have backlight big screen character suggestive LCD display. 
* Can display when power out and activation by the page turning key. 
* Telecommunication function: infrared, RS**5 and power line carrier telecommunication function.
