The evolution of AMI (Advanced Metering Infrastructure) for demand response is an important enabler of the coming smart grid. The underpinning appliances, smart meters, have evolved into complex, full-function products that provide metrology, monitoring and control as well as real-time communications.  From simple remotely-read meters, the power needs of these feature-rich units have increased from miliwatts to watts, and can no longer be powered by a simple transformer or battery.

Whether youíre working on your first design, or already looking to optimize your next generation meter, Bias Power can help.  Bias compact 2W and 4W ac/dc modules, using patented technology, offer many advantages compared to discrete power designs. Unlike other switching power supplies, our modules produce no conducted EMI, thus eliminating the need for bulky filtering. And due to their low radiated EMI, they are also compatible with the most popular communications, including Zigbee.

The Bias constant power module can be less expensive, more cost-effective than your existing design! Most switching power solutions are sized to address the peak-power requirements, but with Bias you can greatly reduce costs by sizing for average power and adding an external capacitor. We can also help to achieve even lower costs for higher volumes; Bias proprietary reference design provides a migration path to a discrete solution utilizing our custom ASIC controller and proprietary transformer.
