Product Description

Single Phase STS Prepaid Electricity Meter BS footprint Extended terminal cover steady broad voltage range

As the fundamental meter type of prepaid meter, the DDSY168 is designed and finished with a BS8565 standard housing and customer interface keypad. It operates with the current from 5 to 80Amp maximum.It is built with the rugged RF immunity withstand of 30V/m and IP54 rating, and therefore is able to operate in harsh environments. The meter is can be utilised as a credit meter as well as a prepayment meter to be vended with STS(Standard Transfer Specification) standard. The consumer can punch in the credit token number via the meter keypad to get  recharge.

Main Features

1) SRE- significant reverse energy detection and measurement

2) IR optical port compliant with IEC62056~21 

3) Operate in both prepayment and post payment mode

4) Disconnects on overload and credit exhausts

5) Adjustable power limit and low credit warning level

6)Anti-tamper detection such as opening cover, reverse connection, blackout and etc.
