Sanxing selects IDT Energy Metering IC for single phase smart energy meter


San Jose, CA, U.S.A. — (METERING.COM) — January 12, 2011 – Ningbo Sanxing Electric Co., Ltd. has selected Integrated Device Technology, Inc.’s  single phase energy metering IC for use in its single phase smart energy meter.

The IDT90E24, which was selected for its wide dynamic range, belongs to a family of high performance energy metering ICs for single phase two-wire, single phase three-wire or electricity meters with anti-tampering mode. With a dynamic range of 5000:1, it enables accurate measurement of several tens of kilowatts down to just a few watts. Thus the device is ideal for measuring large power consumption during peak load hours, and also for measuring small amounts of generated power from renewable sources such as solar and wind during off-peak hours.

“IDT’s newly released IDT90E24 product features a wide dynamic range, making it suitable for applications with a wide metering range requirement,” said Zhongxiang Zhou, chief electronic meter engineer at Sanxing Electric Co., Ltd. “It passed all of Sanxing’s internal tests and won positive recognition from our customers.”

The IDT90E2x is offered in a Pb-free 28-lead SSOP package, and is designed for long term stability over variations in ambient environmental and grid conditions. The device 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.

“We are pleased to have our smart energy meter selected by Sanxing,” commented Sean Fan, vice president and general manager of IDT China, adding: “We will continue to deliver complete smart metering solutions to benefit both meter manufacturers and utilities economically and environmentally.”

Ningbo Sanxing Electric Co., Ltd. is one of the largest electric meter manufacturers in China with a production capacity of up to 25 million energy meters and a 30 percent market share.
