Application of Smart Meters


Smart meters are big news. The overall smart meters penetration rate for global market is expected to reach 61% by 2026.

With the energy supplies demanding more advanced communication interfaces, large memory and more powerful microprocessors, it requires wider/ higher operation voltages (up to 500 VAC ) and lower power consumption of power supply designs.

What else? The size limit and magnetic immunity are also driving the demand for more innovative power supplies designs----compact size and EMC protection.

Considering all the demands, MORNSUN releases new product LS03-16BxxSS/LD03-16Bxx series, offering an ultra-wide input voltage range of 90~528VAC, covering requirements of  3×220VAC/380VAC/480VAC nominal voltage. They also provide high efficiency up to 76%, 4000VAC isolation and output short-circuit and over-current protections.

 It is widely use in the applications of smart meters , instrumentation, fire protection system, etc.

Application of Smart Meters

1. LS03-16BxxSS can get AC input directly from any phase voltage or line voltage and convert to an isolated DC power.

2. High isolated transceiver module TD501D485H can also be selected as a package serial communication, which has integrated DC-DC isolation, RS485 and save your precious engineering time.
