IDT wide dynamic range power metering IC selected by Gude GmbH for expert power meter

SAN JOSE, USA: Integrated Device Technology Inc. (IDT) announced that the IDT single-phase energy metering IC has been selected by Gude Analog- und Digitalsysteme GmbH, a leading manufacturer of Power Distribution Units through TCP/IP networks, for use in its Expert Power Meter. Gude selected the IDT energy metering IC because of its high accuracy and wide dynamic range; the widest in the metering industry.

The IDT90E21 is a high-performance energy metering device for single-phase two-wire, single-phase three-wire or electricity meters with anti-tampering mode. It boasts the industry’s widest dynamic range of 5000:1, which facilitates measurement over a large current range of 20mA to 100A. The device measures RMS voltage and current, phase angle, voltage frequency, power factor, and mean active, reactive and apparent power.

“Gude is a leading maker of high quality power distribution units,” said Dr. Michael Gude, CEO and Founder of Gude Analog- und Digitalsysteme GmbH. “We have very stringent standards on features and performance for our Expert Power Meter products. IDT’s power metering solution offers great accuracy over a large range, which is important for our product differentiation and competitive advantage.”

“Incorporating IDT's proprietary analog-to-digital converter (ADC) and DSP technologies, we have entered a new market with this innovative power metering product, which has gained customer traction in China, Europe, and beyond. We will continue to deliver complete smart metering solutions that are vital to improving energy efficiency for electricity distribution and consumption worldwide,” said Sean Fan, VP and GM of IDT.

The IDT90E21 is fully compliant with IEC62052-11, IEC62053-21 and IEC62053-23 specifications for class 1 or class 2 single-phase watt-hour meters or class 2 single-phase var-hour meters. The device is offered in a lead-free 28-lead SSOP package, and is designed for long-term stability over variations in grid and ambient environmental conditions.
