DDSI1 electronic three-phase multi-function energy meter
1.main functions and features:
1)Measure bi-directional active/reactive and four quadrants
reactive energy at different time periods.
2)Infrared communication, 485 communication and carrier wave
3)4 tariffs, 12periods, 5 set schedules, 4 zones and 12 public
holidays can be setup.
4)Measure and displaying parameter of voltage, current on phase A
.B. C, power factor and total active power.
5)Function of broadcast synchronization, Reprogram has been
limited, demand recovers and data reset.
6)Meter has alert function of voltage or current losing, reverse
phase sequence voltage. Record the event of voltage or current
losing, reverse phase, pass rate of voltage, programming, demand
reset and broadcast synchronization.
7)Frozen energy, and keep saving with recent month-ending energy of
3 month, automatic frozen energy for daily null-point and hourly
each clock. Energy can be saved 7 days with daily null-point, and 2
days for hourly each clock.
8)Can be reprogram by PC or HHU
9)Data on LCD screen can be rolling automatically and rolling
content can be setup, also can be checked by press button or remote
control to inquire data.
10)Remote control for power on or off, and output 1 route braking
interface point.
11)Active/reactive test impulse output port.
