Three Phase Multi Function Energy Meter Type DTSD999

Three Phase Multi Function Energy Meter Type DTST999 is a high-tech intelligent instrument to measure measure three phase active and reactive energy. This type of meter adopts large-scale IC-circuits, FRAM (ferro-electric memory technology), RS485 / RS232 communication ports and an infrared communication port, Large LCD-Display, wide temperature scope, real-time clock, electromagnetic compatibility (EMC) and advanced SMT production crafts.

Main Functions

• Measurement of total active energy, total reactive energy, forward active and reactive energy, reverse active and reactive energy and total four quadrants reactive energy and time of sharing energy.
  
• The formula of the total active and reactive energy, import and export total active energy and import and export total reactive energy can be programmed
• Measure the maximum demand of the total forward and reverse active energy, forward and reverse reactive energy, four quadrants reactive and interval time along with the date and time of occurance
• 8 tariffs, 14 time zones, 12 day tables and 14 time periods programmable
• 32 kinds of load curves to record data: last 4 months, voltage qualirt rate and time of beyond upper limit and beyond lower limit
• Record last 10 events 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 voltagephase 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
• Adopt safety system certification and data encryption to ensure data security and correct data
  
• Four programmable output devices: relay, light coupling, alarm indicator light and buzzer. All equipment can be output through user programming method
• Program an read out meter: RS485/RS232 and infrared communication portscomplied to IEC 1107
