Digital Watt-Hour Meter

M B Control & Systems introduces the latest power monitoring system (PM 295) with disturbance and harmonics analysis. This most advanced and high accuracy (0.2%) power meter offers unique features at very low price. The power meter (PM 295) is ideally suitable for monitoring of electrical parameters and disturbance in the power lines. Power meter Model 295 provides display of all the three phase electrical parameters, ie, voltages, currents, unbalanced current, power factor, active power (kW), reactive power, apparent power (kVA), active energy (kWh), reactive energy, apparent energy, requency, max amps demand, reactive energy (kVAh), Returned Energy, and % total harmonic distortion. In addition to above the power meter (PM 295) provides up to 512 KB on board non-volatile memory. This memory can be used for logging electrical parameters, internal, external events and wave forms. Wave forms can be stored depending on external or internal triggers. Up to sixteen cycles can be stored prior to or after the trigger. This allows disturbance analysis of the power line. These stored wave-forms can be viewed and plotted by use of PC and the software available. The power meter (Model PM 295) provides harmonic analysis till 39th harmonic four relay outputs, eight potential free inputs, sixteen set points, eight energy registers, real time clock and calendar, eight counters, four timer counters and serial RS-232/422/485 interface.
