0.0 0.0

 

The main technical parameters

model

DTZ110

name

Three-phase intelligent electric energy meter

level of accuracy

0.5S level 1 level 2 level

Rated frequency (HZ)

50

Dimensions (mm)

290 × 168 × 91
Rated voltage (V) 220 110 57.7
Basic current (A) 1.5 (6) 2.5 (10) 5 (20) 5 (30) 10 (40) 15 (60) 20 (80)
Daily timing error (s / d) ≤0.5
Starting current 0.1% Ib
Rated frequency (Hz) 50

 

 

Main functions and features:

1. The meter can measure forward and reverse active power, forward and reverse apparent, 1, 2, 3, 4 quadrant reactive power and A, B, C phase active and reactive power, and can set combined active and reactive power. The characteristic word performs selective addition and subtraction of positive and negative active energy and four-quadrant reactive energy to generate combined active power, combined reactive power 1, combined reactive power 2 and electricity.

2. All kinds of electricity can be time-shared and measured according to the total and maximum 4 time periods (A, B, C three-phase time-shared measurement).

3. Can store electricity data for 12 settlement cycles.

4. Maximum 4 rates. Each set of time zone table can set up to 12 time zones.

5. Electrically isolated RS-485 communication interface, designed with protection circuit.

6. The infrared communication interface and RS-485 communication interface are physically independent and can communicate simultaneously without interfering with each other.

7. The communication protocol symbol DL / T645-1997 communication protocol complies with the supplementary protocol of Anhui Province.

8. Sampling hardware clock circuit, backup battery adopts imported green environmental protection battery.

9. The electric meter can record the events of opening the meter cover and the button cover.

10. Comply with GB / T17215.321, GB / T17882-1999, GB / T17883-1999 and DL / T614-2007 and other energy meter related standards.

Main functions and features:

1. Active energy measurement, no need to adjust for long working hours.

2. Three rates, 12 periods, LED indication rate period is clear and intuitive.

3. Store the energy data of each rate in December.

4. Reverse power is counted in forward power.

5. Electrically isolated RS-485 communication interface, designed with protection circuit.

6. The infrared communication interface and RS-485 communication interface are physically independent and can communicate simultaneously without interfering with each other.

7. Communication protocol symbol DL / T645-1997 communication protocol, symbol Anhui Province supplementary protocol.

8. Sampling hardware clock circuit, backup battery adopts imported green environmental protection battery.

9. The meter can record the event of opening the meter cover and the button cover.

10. Symbol GB / T17215-2002 GB / T15284-2002 DL / T614-1997 standard requirements.
