DDSY150 single phase prepaid electronic meter is used for measuring single-phase AC active energy with rated frequency of 50Hz to realize using electric power after prepayment. The product adopts IC card (named as smart card) and advanced micro-electronic technique to collect, process and memorize data. Its technical performances are complying with the requirements of national standards of GB/T18460.3 and IEC61036. It has strong function of preventing the meter from decoding, compatibility as well as features of small size, weight light and high reliability.
System Configuration:
1.Prepaid Meter
2.Card reader
3.Prepayment Software
Working principle:
1. Both-way electric energy metering: provides precise positive-negative active energy metering and one-way accumulating; used for power metering and advance purchase of AC single-phase current rated
2. Advance purchase quantity, preset maximum load-limit and IC card password; IC card transfers data and realizes data including total consumption, remaining quantity, accumulated quantity and total purchases) backward reading
3. Storage of leave-factory serial number, meter constants, initial data and the user's name and address
4. Alarm and switch off when overload; alarm at low remaining power to remind user of timely purchasing
Features:
1.LCD display:With backlight and display Chinese characters
2.Display 8-digit :Display 2 decimal places
3.Remaining amount, total electricity consumption & total amount :2 decimal places, Up to 999999.99
4.Single price:Pricing is up to 6 decimal places
5.IC card type:Contact card(4442 card) OR High-frequency RF card(M1)
6.Overload alarm:When the user average power exceeds the preset value for more than one minute, the electricity meter will automatically stop power supply. It will resume power supply automatically 5 minutes later.
7.Power-off alarm:When electronic shortage, remind users to buy electricity timely
8.Overdraft electricity:Allow set the overdraft electricity

Who is a Prepayment Meter suitable for?
Firstly is Landlords who rent their property out. Many landlords choose to install a prepayment meter as it means their tenants are responsible for paying for their electricity as they go and won't leave the landlord with an unexpected bill to pay if they move out. Also it reduces any headache of changing the names registered with the energy company each time a tenant moves out and a new tenant moves in.
Secondly, a prepayment meter may be a good idea for those that have struggled to keep up with bill payments in the past. If a customer has fallen into debt with their energy company, the energy company may install a prepayment meter to help the customer control their budget.
