ACQUISITION SETTINGS■ Bandwidth Settings PPA5500DC(DC-5Hz)Low(DC-200kHz)Wide(DC-2MHz)DC measurements up to 5HzBasic power (50/60Hz) including harmonics of thefundamental while rejecting high frequency noiseWideband applications such as PWM inverter drivesincluding all power components for true total powerNoteExample of independent wiring configurationshowing 3 phase individual coupling settingsThe PPA5500 series includes a programmable digital filter that allows users to set a preferred bandwidth■ Display Settings, Smoothing Response and Frequency Reference PPA5500 PPA1500 PPA5001Display update rateVarious settings for the displayupdate rate (12.5ms ~ 10s) whichalso increases the smoothing whenused together with the smoothingoption. A 'window' option permitsdirect control of the measurementwindow sizeExample of setting the window, eg (50Hz set to 20ms)2Smoothing settingsWorking in conjunction withthe speed setting, a smoothingfilter can then be applied to themeasurements. Normal and slowoptions are available which applyan increasing time constant to theoutput of the measurement window・Display update speed settings・Setting the filter (normal/slow)■ Frequency Reference PPA5500 PPA1500 PPA500When making a precision measurement of ac power,correct synchronization with the fundamental frequencyis essential. The PPA series provides a solution tofrequency synchronization in a wide range of applicationsincluding Standby Power, Variable Speed Drives,Electronic Ballasts and DC to AC Inverters with the optionto select voltage, current, speed or ac line input as thefrequency reference. The PPA5500 series also providesfully independent frequency detection an all phase inputsSpeed Input PPA5500 only1:5 cycle (10Hz standby current period)Power measurements synchronized to low duty cyclecurrent pulses of a power supply in standy mode1:5 duty cycle standby power measurement cycle1:50 low duty cycle (1Hz) power measurement10
