Newtons4th Ltd Model PPA1500 compact power analysers

Newtons4th Ltd Model PPA1500 compact power analysers are available in 1-, 2- or 3-phase configurations. They offer 1 MHz bandwidth, full oscilloscope display of voltage and current waveforms, harmonic bar graphs and graphical data logging, as well as tabular digital displays.

The PPA1500s are fitted with internal current shunts (with options for external shunts) rated to 20 A RMS with 300 A Peak capability. The current shunts have very low phase angle error for precision power measurement in low power factor applications. Maximum input voltage is 2500 V peak (1000 V RMS) divided into eight separate ranges.

The PPA1500s can be connected to current transformers and voltage transformers and the ratios programmed in so they read out directly in kilovolts and kiloamps. They are also said to offer x10 gain mode for standby power measurement, and Inrush current mode.

The PPA1500s offer real-time analysis of electrical power with no measurement gap. They are fitted with a range of interface options including LAN, USB and RS232 ports. They can be operated from a PC using the optional software or as a standalone instrument.
