Electricity Meter Power Supply Design

Tue, 08/28/2007 - 6:07am

Power Integrations introduces its power supply design idea (DI-141) which is based on the proprietary LinkSwitch-XT family that enables anti-tampering protection in electricity meter applications. It offers an isolated power supply in flyback configuration that delivers 150 mA at 5V under an intense external magnetic field, the most commonly used method of disabling meters without alerting existing anti-tampering measures. This product family includes EcoSmart technology which optimizes the efficient conversion of energy at different load levels. By replacing traditional linear power supplies with the design idea, the 2W of power used by power meters can be reduced to around 1W while still providing the 750 mW of power required by the advanced meter electronics.
