San Jose, CA, U.S.A. — (METERING.COM) — December 1, 2010 – Mixed signal semiconductor solutions provider Integrated Device Technology, Inc. has announced that its single phase energy metering IC has been selected by Gude Analog- und Digitalsysteme GmbH for use in its Expert Power Meter.

Gude, a manufacturer of power distribution units through TCP/IP networks, selected the IDT energy metering IC because of its high accuracy and wide dynamic range.

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 a dynamic range of 5000:1, which facilitates measurement over a large current range of 20 mA to 100 A. The device measures RMS voltage and current, phase angle, voltage frequency, power factor, and mean active, reactive and apparent power.

“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,” said Sean Fan, vice president and general manager of IDT. “We will continue to deliver complete smart metering solutions that are vital to improving energy efficiency for electricity distribution and consumption worldwide.”

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.
