Application
DTSF238 three phase electrical multi-rate
watt-hour meter is a kind of new-style meter which is developed on
the base of DDSF 238 single phase electrical type multi-rate
watt-hour meter and widely heard power supply system experts and
many users’ opinions and absorb domestic and overseas new
techniques. It is a kind of potent measuring instrument for
adjusting electric power load and reasonably prepare electric power
source. It can user electric energy consumption by use-of time. Its
technical performance are completely conform to the stipulated
requirements of National Standard GB/T17215-2002《Class 1 and class
2 static type alternating current active energy watt-hour meter》
and GB/T15284-2002《Multi-rate ( time-of use) watt-hour meter》.
The meter is used for measuring
rated frequency 50Hz or 60Hz three phase AC active energy electric
power consumption and can realize many tariffs calculating cost and
collecting transcription meter functions.
Structure and features
1.Palm type computer, infrared remote controller programming
setup, transcription meter, distinguished by code.
2.The message is preserved forever if power is interrupted, inner
emplaced spare batteries and are free of maintenance.
3.Module type switch and power, wide voltage range.
4.Can connect with computer, realize data copy and printing.
5.Have three tariffs, four time zones, four daily period of times.
6.May realize data display by turns.
7.May choose 485 interface and long-distance pulse interface to
realize collecting transcription meter.
