The Dranetz PowerXplorer® PX5 is a portable, hand-held, eight-channel power quality meter/monitor. This cutting-edge power quality instrument is designed with a color liquid crystal display (LCD) 1/4 VGA, using touch screen technology. It can monitor, record and display data on four voltage channels and four current channels
PX5 is designed to meet both the IEEE 1159 and IEC 61000-4-30 Class A standards for accuracy and measurement requirements. It can do PQ-optimized acquisition of power quality related disturbances and events. It is designed with a statistical package called Quality of Supply (QOS), with monitoring and setup protocols set to determine voltage
measurement compliance required for EN50160 monitoring. European standard EN50160 requires that measurement parameters must be within a specified percentage for 95% of the time.
PowerXplorer PX5 is available in two models:
• Model PX5-XFAST is equipped with the high speed sampling analog board for microsecond transient detection digitization and analysis. The PX5-XFAST performs measurements for 50/60 Hz power frequency systems.
• Model PX5-400 performs measurements for 400 Hz power frequency systems. The PX5-400 will also monitor at 50/60 Hz. The user needs to set the default frequency to either 400 Hz, 60 Hz or 50 Hz, depending on the application. When operating at 400 Hz, rms calculations are made on a cycle-by-cycle basis with 1 cycle step; whereas at 50/60 Hz mode, it steps at 1/2 Hz. Also, the PX5-400 does not calculate the IEEE 1459 power parameters as well as flicker, which are not defined at 400 Hz.
