Power Integrations Introduces Efficient, Tamper-Proof Electricity Meter Power Supply Design

August 6, 2007
Innovative Meter Design Slashes Waste and Deters Fraud

SAN JOSE, Calif., Aug 06, 2007 (BUSINESS WIRE) --

Power Integrations (OTC:POWI), the leader in high-voltage analog integrated circuits for power conversion, today introduced a new Power Supply Design Idea (DI-141) based on the company's highly successful LinkSwitch-XT family that enables anti-tampering protection in electricity meter applications.

In some countries it is estimated that five percent of electricity production is consumed illegally through tampered meters, a very real and high cost to utility companies. New and effective anti-tampering strategies are in continuous demand by meter developers. The Power Integrations design idea offers an isolated power supply in flyback configuration that delivers 150 mA at 5 V, even under an intense external magnetic field, the most commonly used method of disabling meters without alerting existing anti-tampering measures.

Power Integrations' LinkSwitch-XT family includes EcoSmart® technology, which optimizes the efficient conversion of energy at different load levels. By replacing traditional linear power supplies with the PI solution, the 2 W of power used by power meters, the maximum amount recommended by the International Electrotechnical Commission (or IEC), may be reduced to around 1 W while still providing the 750 mW of power required by the advanced meter electronics. The PI solution thus reduces energy expended in metering by 50 percent.

Comments Silvestro Fimiani, product marketing manager at Power Integrations: "Adoption of this technology is an effective way for utility companies - which are investing millions of dollars worldwide to install an Automatic Meter Infrastructure (AMI) - to recover part of their huge investment by saving energy."

DI-141, complete documentation for the LinkSwitch-XT family, and a description of Power Integrations' EcoSmart technology can be found on www.powerint.com.
