Three Phase Multi-Tariff Energy Meter Type DTSF999
Three phase multi-tariff energy meter type DTSF999 is used to measure 50 Hz or 60Hz active energy and power flow of peak time, shoulder time, flat and off-peak time.All of its functions comply with the relative technical requirements for class 1 three phase whatt hour meter in IEC 61036-2000. Using the RS485 communication port you can program tariff periods and time
It is a new and high-tech adopting special large-scale IC, latest micro electronic technology and SMT production crafts.
It is designed for rough working condition and components selection as foundation. This all leads to a long-term stable operation.
Main Function
- Four tariffs: Total, T1, T2, T3 and T4
- Displaying and recording the total power and peak, shoulder, flat and valley of present month, previous month and previous 2 months.
- Maximum Demand cycle: is 15 minutes
- Slipping time: 1 minute
- Recording and displaying reversed power
- Displaying and recording phase absence
- Display turns: total, T1, T2, T3, T4, Demand 1, Demand 2, Demand 3, Time and Date
- Displaying and recording the total power
- Infrared Communication: Reading power consumption, setting period, setting meter no., adjust date and time
- RS485 Communication: Reading power consumption, reading maximum demand and occired time, reading phase absence times and periods, reading last phase absence starting and stopping time, settting meter no. and adjust the date and time
- Manual programming button: Setting period and adjusting date and time
