Power from the phase

"Having the ability to power the Dranetz HDPQ SP instruments from the circuit being measured is a great convenience to users, and it also enhances their safety," said Ross Ignall, Dranetz Director of Product Management. "With the new, built in, 600VAC/DC power supply, users no longer have to locate a separate 120/230V power source for the instrument; they now have the choice to either power the instrument from the circuit being measured or from a separate power source."

Dranetz HDPQ users can now choose between a traditional portable instrument with a local 7" colour touch LCD display or a SP version that can be powered from the phase, and is housed in an IP65 enclosure without a local LCD display. The HDPQ portable (with 7" display) and SP (IP65 enclosure without display) versions of each model have exactly the same measurement and strong remote communications capabilities.

The Dranetz HDPQ Family of Power Quality, Demand & Energy instruments not only offer measurement capabilities, but also have what the company claims to be the most powerful communications capabilities in the industry making it suitable for commissioning, engineering, and troubleshooting applications.

The communications available in the Dranetz HDPQ line enhances the end users productivity and safety by allowing users to control the instrument and download data remotely. Users no longer have to subject themselves to hazardous environments and can now manage power surveys remotely from the safety and comfort of an office or other more convenient location.
