Model: DTSY1286
Name: Three Phase IC card Prepaid Energy Meter
Introduction: high precision, high reliability, long service life, low power consumption, light weight, convenient for managing

GB/T17215-2002

GB/T18460.3-2001

IEC 62053-21

●It adopts logic encrypted IC card as user electricity purchasing card, the meter works after the prepayment.

●One card just for one meter, fake card is completely avoided.

●Automatic power off when overload, also can prevent the error overload when the load restart

●Display by both mechanical calculating device and numeral tube.

●Two alarm grade to remind purchasing electricity.

●The forward and opposite direction active power can be measured accurately

●Compute the amount of electricity normally in the absence of the phase

● Embedded large power latching bi-stable relay is used to cut off power supply directly.(except 1.5(6) A ), low power consumption, high reliability.

●The electricity is not used for 6 days, energy meter send the power cut off signal.

●It has the functions of failure checkup, anti-stealing electric power and meter record.

●The electricity purchasing card writes back the information of user’s power consumption automatically.

●It can display the operation situation of energy meter every 10 seconds, including current power consumption information, remaining capacity, power cutoff information and error information.

●The pulse indicator light imitates the traditional energy meter’s turn plate to indicate the status of meter.

●The 1.5(6)A meter has switch out indicator light to indicate the meter has sent power cutoff signal and relay K1 action, the external breaker cutoff the power supply. The other meter has the warning indicator light to indicate the remaining power reaches the deadline, reminding the user to purchasing the electricity ASAP.

●The meter has the high stability and reliability. It is no need to adjust & regulate when long term operation. The data can be saved for a long time if the power is cutoff.

●Wide working temperature range, low request to working environment
