DKM-409 Pro AT User Manual Rev_02 Firmware V-2.5DKM-409PRO ATNETWORKANALYSERThe DKM-409-Pro-At is a precision instrumentdesigned for displaying, logging and remote monitoringvarious AC parameters in a 3-phase network.The power supply of the unit is isolated. The standardsupply range is 100-265V-AC and 88-400V-DCallowing universal use in AC and DC systems.The unit has 3 x 4-20mA analog outputs. Anymeasurement can be output as analog value.The unit has 4 digital inputs and 2 relay outputs withprogrammable functionality, selected from a list.Thanks to its isolated RS-485 Modbus RTU comport,the device is free from ground potential differenceissues and data are safely transferred to automationand monitoring systems.The device has 1MB internal memory for the record ofall electrical parameters with required frequency.Records are read through Modbus.The graphic screen allows display of waveforms andharmonic analysis graphs.The user configurable screen where any measuredparameter set can be displayed, transforms the unit toa custom designed measurement panel.Ph-N and Ph-Ph volts: V1-V2-V3-U12-U23-U31Phase and neutral currents: I1-I2-I3-InPhase and total, active/reactive/apparent powers:P1-P2-P3-Q1-Q2-Q3-S1-S2-S3-ΣP-ΣQ-ΣSPh and total power factor: pf1-pf2-pf3-ΣpfActive and reactive counters: Pimp1-Pexp1-Qcap1-Qind1, Pimp2-Pexp2-Qcap2-Qind2User counters: USR1-USR2-USR3-USR42...49 Harmonics of any voltage or currentTrue RMS measurements0.5% measurement accuracyDC supply version availableInternal 1MB record memory (optional 16MB)Harmonic distortion display (49 harmonics)Oscilloscope, waveform displayMax demand displayUser configurable display screenFully isolated RS-485 serial portMODBUS-RTU communication2 configurable relay outputsEnergy pulse output capability4 optically isolated, configurable digital inputs3 isolated, programmable 4-20mA analog outSwitched dual active-reactive power countersIndependent mains/generator energy meteringConfigurable user countersVoltage transformer ratio for MV applicationsPassword protected front panel programmingFree configuration programMini-USB port for programmingHigh visibility, 128x64 pixels graphic LCDReduced panel depthWide supply range 100-265VAC / 88-400VDCWide operating temperature rangeSealed front panel (IP54)Plug-in connection systemMEASUREMENTSDESCRIPTION FEATURES
