Jupiter

Elcontrol Energy Net, leader-company in the field of measurement and control of electrical parameters, has expanded its range of portable analyser range with JUPITER, a high-performance Power Quality Analyser.

Further to measurement of all traditional electrical parameters, Jupiter is capable of analysing the major phenomena characterizing Power Quality: interruptions, voltage variations (dips & swells), harmonic and interharmonic distortion, transients and 3-phase voltage unbalance. Furthermore, Jupiter is also capable of verifying the compliance of the power supplied by the system with the limits set by the EN 50160 standard.

The measurement methods are compliant to the EN 61000-4-30 standard.

The colour LCD display allows visualization of data-tables, real-time waveforms of the measured signals, voltage and current transients, vector diagrams and bar-graph display of the harmonic spectrum, while the alphanumeric keyboard makes it easy and user-friendly.

With Jupiter it is possible to perform particularly detailed measurement surveys, saving the data on a COMPACT FLASH memory. The stored data can be successively analysed on a Personal Computer using the included PQ Studio software.

A full set of accessories make this a truly complete system: 3 flexible Rogowski-coil current transducers (without external amplifier/battery), 6 voltage measurement cables with crocodile clips, 10 rechargeable batteries (Jupiter is equipped with an internal battery charger), external desktop power supply, Compact Flash, Analysis software PQ Studio, shock-resistant IP64 carrying case.

The long operational life-time of Jupiter is guaranteed by its open-source Operative System, continuously updated and made available to the users by Elcontrol's development team upon any modification of the Power Quality Standards (files are downloadable to the Compact Flash from the Internet).

To increase the battery operating time of JUPITER, the screen backlight is switched off if no key is pressed for 3 minutes (press any key to switch it on again).

NOTE 3

The instrument turns off automatically if the batteries reach a voltage level below 5.9V, to prevent excessive battery discharge.
