Polyphase Multifunction Energy Meter

DTSD/DSSD876-ZA meter is a high precise three-phase electronic energy meter, for measurement and registration of active energy and reactive energy.

Main Technical Features:

Can measure the total import/export active energy and Time Of Use;
Can measure the total reactive energy of forward/reverse and four quadrant;
Can measure total M. D. Of forward/reverse active and M. D. For Time of Use
Can measure total M. D of forward/reverse reactive and four quadrant reactive;
Can set 4 tariff, 10 time period, 4 time zone, 5 day time table and 12 holidays;
Event Record: Record for M. D. Reset, programmed, off-power, off-phase, loss voltage and current, over voltage, over-load and load curve, check clock and set meter.
Can save 3 month data for energy, M. D., voltage qualification percentage;
Can save 10 times events record.
Frozen the data on the end date of month;
Can measure voltage, current, power, phase angle, power factor and frequency.
Can measurement wave distorted alternating current and 2~31 harmonic contents;
Correct the CT'error.
With RS485 and infrared communication port;
Reading after power failure is available with infrared port;
Normal measurement under 1 phase(for 3P3W meter) or 2 phase (for 3P4W meter) off-power.
Temper & Fraud Protection
LCD display with English characters.
Using the latest international BMC compound material as panels, the meter has arc-resistant, anti- ultraviolet radiation, preventing from burning function.
