DTSF999: Three Phase Multi-Tariff Energy Meter

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.
