Power Integrations: Designing Efficient, Tamper-Proof Electricity Meter Power Supplies
|
|
In some countries, an estimated five percent of electricity production is consumed illegally through tampered meters.
Meter developers are always looking for new and energy-efficient ways to deter power theft.
Power Integrations has come up with a solution based on the LNK363DN device.
