Detailed Product Description

DTSD5-T, a basic Poly-phase multi-tariff meter. It is developed under the ongoing technology evolution in the residential sector and in order to meet the growing customer demand for static meters. It gives advantages to all users in the process: an installer, a maintenance engineer, a service engineer, a readout operator and a final user. The meter is approved and manufactured in compliance with the IEC 62052-11, IEC 62053-21 (IEC 61036) standards, and was designed according to even higher internal PAX-HUALONG standards.
An outstanding advantage of this compact, cost-effective meter is its easy-to-read LCD, instead of a drum register. It keeps the user continuously up-to-date with energy consumption and provides an optical data interface for local automatic reading by handheld units (HHU).

Reliability and stability. With proven electronic technology, long-life components and special care in the manufacturing process, DTSD5-T guarantees precise accuracy and high reliability throughout its life span.  Re-calibration is no longer necessary.
 
Fast and Easy Installation procedure
This design is easy to handle and extremely efficient for large-scale residential installations. Adapted to current connection standards the meter is compatible with existing installations and test benches.

Local metering data display (LCD):
Automatic Scroll mode
Manual scroll (by button)
Programmable data set and sequence
LCD back-light: optional
LCD display when power absent: optional

Flexible Tariff Management
Benefit from an internal RTC, full Time of Use (TOU) function is realized.

A tariff program are managed by the RTC which suitable for the most complex metering applications. The meter is able to generate End of Period information as defined by the user, usually based around billing dates. The non-volatile memory is able to save energy information for up to 12 billing periods. This removes the need to visit the meter on a frequent basis.

DTSD5-T supports 4 kinds of tariffs and 12 intervals in 24 hours for each day, which can be programmed flexibly. Interval 1 to 12 of each day can be combined with tariff 1 to 4 according to various requirements, these combination is called Tariff Set. In addition, the meter supports  holidays & weekends, which can be individually set with different kinds of combination of tariffs and intervals.Maximum Demand information can also be measured for all tariff rates allowing optimum billing of high consumption customers in particular.

Registering Modes

Mode 1: Import per phase (anti-reverse function set for each phase)
Mode 2: Ferraris-like (simulation of induction watt-hour meter)
Mode 3: Unidirectional (always positive register)
Mode 4: Bi-directional (both import and export)
