Three Phase Multi-function Energy Meter Type (DTSD999)

Three Phase Multi-function Energy Meter Type (DTSD999)

Product Description

Three phase Multi-function energy Meter type DTSD999 is a hi-tech intelligent instrument to measure three phase active and reactive energy
This kind of meter adopts large-scale IC circuit, FRAM (ferro-electric memory technology), RS485/RS232 communication ports and infrared communication port, LCD display with large screen and wide temperature scope, real-time clock chip, electromagnetic compatibility (EMC) and advanced SMT production crafts.

Main Function
1. Measure total active energy, total reactive energy, forward active& reactive energy, reverse active & reactive energy and total four quadrants reactive energy and time of sharing energy;
2. The formula of the total active and reactive energy, Import and export total active energy, Import and export total reactive energy can be programmed:
3. Measure the maximum demand for forward & reverse active, forward & reverse reactive, four quadrants reactive and interval time along with the date and time when it occurred;
4.8 tariff, 14 time zones, 12 day tables and 14 time periods programmable;
5. Load curve: Support max. 32 kinds of load curve to record data; Record last 4 months' voltage quality rate and time of beyond upper limit and beyond lower limit.
6. Record last 10 times' event and related data: Phase failure, loss voltage, total loss voltage over voltage, loss current, current unbalance, over power, over demand, system reset, clock set, data /demand reset, check clock, program, on/off power; The related data of loss voltage, phase failure and loss current events include: Starting time, ending time, total active energy, forward active energy, reverse active energy, total reactive energy, forward reactive energy, reverse reactive energy, average voltage, current integrate and active demand.
7. Adopt safety system certification and data encryption to ensure data security and correct;
8. Four programmable output device: Relay, light coupling, alarm indicator light, buzzer; All equipment can output through user programming method.
9. Program and reading: Via RS485 and infrared communication port complied to IEC1107.
