High Speed Transient Capture

Advanced Remote Wireless Communications

Made in the USA


The Dranetz HDPQ Xplorer 400 Plus (portable)  power quality analyzers take PQ, Demand and Energy monitoring to new heights by adding 400Hz monitoring capabilities to the already powerful Dranetz HDPQ Xplorer family. The Dranetz HDPQ Xplorer 400 is designed for applications such as aviation, naval, military, etc. requiring 400Hz capabilities that are not available in most PQ and Energy analyzers which typically only measure 50/60Hz. The Dranetz HDPQ Xplorer 400 family was designed with 400Hz applications in mind, but it is also an all-purpose tool that can be used for any traditional 50/60Hz application. In addition to the 400Hz applications, the Dranetz HDPQ Xplorer 400 family is perfect for applications such as power quality surveys, voltage and current transient studies, fault recording, inrush, motor testing, harmonic analysis, advanced distortion analysis, demand/energy/load studies, and many more.

The Dranetz HDPQ Xplorer 400 is a true hand-held portable instrument with a built in 7″, tablet-like touch LCD display.  The Dranetz HDPQ Xplorer 400 family of power quality instruments offers you the best in class monitoring capabilities available. In addition to the 400Hz capabilities, it measures to all current industry standards, including IEC 61000-4-30 Class A, IEC 61000-4-7, IEEE 1159, IEEE 519, IEEE 1459, and more. With its high speed transient data capture (1 microsecond/channel) capabilities, this 8-channel workhorse simultaneously captures and characterizes thousands of parameters, by using a range of standard and customizable operating modes. The unique measurement capabilities include capture of low-medium-high frequency transients through peak, waveshape, rms duration and adaptive high-speed sampling, as well as power measurements to clearly characterize harmonics, non-sinusoidal, and unbalanced systems. The Intelligent AnswerModule® feature provides consultant-like analysis of sag directivity, capacitor switching transient identification/directivity and motor analysis/reporting.

The Dranetz HDPQ Xplorer 400 family enables users to review data and change settings remotely from virtually any smartphone, tablet, mobile device, as well as with traditional PC and MAC laptops and desktops. Just hook up the instrument, close the cabinets to the ‘safe’ environment, and use either the VNC interface along with our Dran-View 7 software or our Dranetz HDPQ Apple or Android Apps via Ethernet for remote control from anywhere with connectivity to the instrument.
