DTS1079-D the Intelligent Power Measurement and Control Instrument is designed for monitoring and measuring data consumption status of Public facilities and intelligent buildings, able to measure all the common parameters: power, current, active power, reactive power, harmonic, etc.
l Calculate active power of both positive and negative,input&output reactive power data.
l Measuring the A, B, C three-phase voltage, three-phase current, the phase and the total active power, reactive power, apparent power, power factor and grid frequency, and has the maximum demand record cumulative, storage.
l Clock error within 0.5s/day,automatically switch calendar,timing and leap year.
l LCD displaying:Functions of Scroll-playing and Press-playing.
l Output: Active,reactive power pulse output, passive opto-isolated output port.
l Communication Port:RS-485
l Communication Protocol:MODBUS-RTU (Others customizable )
l Function of Programming:Able to configure meter address,time&date,tariff&period and reset.
l Data reading and power management:Realize the intelligent management by automatically data reading through communication of RS485.
