Product Specification

Combination Meter KVA-KW-PF (DM 3150)

True RMS 4 Digit measurement of KVA, KW and power Factor for sine wave as well as distorted waveforms
Four digit Power Factor measurement
Conveniently accessed DIP switch at rear for CT selection
Flicker free bright 14.2 mm LED display
Auto scroll facility
96 mm x 96 mm DIN x 85 mm Depth, flush mounting case
Built in Syntron Reliability

Applications
Gensets True RMS measurement gives correct values in presence of harmonics
AMF panels Compact instrument for multi parameters and true RMS measurement for the genset
Power control panels (PCCS) compact instrument for multi-parameters
Power Distribution Boards (PDBS ) mots sutable for feeders for DC drives and VFDS
Power factor Control panels Compact multi parameter measurement
Maximum Demand Controllers Compact multiparameter measurement for demand .
Test laboratories for quick checking of instruments

Features
Measurment
Voltage
0 300 V line to neutral of all three phases.
Burden
0 2 VA approx
Current
0 5 Amps in all three phases scaled according to the CT rating selected on DIP swith at rear
Burden
0 2 VA approx
Permissible overload
20%

Frequency
45.00 to 65.00 Hz

Measured values
KVA: for all popular CT ratios from 30/5 to 1500/5 by true multiplication of true RMS voltage and Current measurement .
KW: for all popular CT ratios from 30/5 to 1500/5 by true four quadrant multiplication of voltage and Current measurement.
Power Factor : Unit measures Power Factor by ratio of KW and KVA, and not merely cos phi. This gives true measurement in presence of harmonics.
Accuracy: +/- 0.5%+/- 1 digit of full scale for voltage and current . +/- 0.05 Digits for Frequency meter
Aux supply : 180V to 260V
Burden: 3VA approx

The above measurement specifications are for the following environmental conditions
Operating temperature: -10 to 55deg C
Storage temperature: - 20 to 70deg C
Humidity: less than 95% RH non-condensing

Operation
Switch on : KVA ,KW and power Factor of R phase .
Press switch:KVA, KW and power Factor of Y phase.
Press switch: KVA, KW and power Factor of B phase.
Press switch: KVA , KW and power Factor of sum of R,Y,B phases.
Pressing switch once more reverts measurement back to the state as at switch on.
Instrument goes in scroll mode if the switch is kept pressed for 5 second or more and released
