Kosteffektiv enkelt-fase processor til energimåling
Maxim lancerer fuld autonom processor, der gør det muligt at addere simpel 'utility' grade energimåle- og diagnosefaciliteter til eksisterende designs (in english).
Maxim Integrated Products is now sampling the 78M6610+PSU1)/78M6610+LMU2) single-phase energy-measurement processors.
These processors are an energy-measurement subsystem in a single chip. They provide simple utility-grade sensing and diagnostics for existing designs without the traditional cost of a utility meter system-on-chip. Both devices contain unique firmware to meet end application requirements.
The 78M6610+PSU is specifically designed for real-time monitoring of data centers, servers, and telecom and data equipment, while the 78M6610+LMU is a more general-purpose solution for applications such as white-good appliances, smart plugs, EV chargers, and solar inverters.
The 78M6610 processors enable energy-measurement functionality while reducing both manufacturing costs and time to market. Energy-measurement solutions traditionally required the use of an additional microcontroller, which adds significant design cost and months of development time. The 78M6610 allow users to conveniently add a complete energy meter to an already existing design without significant cost or redesign. Additionally, the processors’ flexible measurement and host interfaces allow for easy integration into any system.
- A more efficient smart grid needs energy measurement at a variety of endpoints beyond the traditional electric meter. The 78M6610+PSU/78M6610+LMU enable these points of measurement with utility-grade accuracy, application-specific firmware, and at a low system cost, says Kris Ardis, Business Director for Smart Grid Products at Maxim Integrated.
- The smart grid benefits from embedded technologies like these processors, comments Christine Hertzog, Managing Director at Smart Grid Library.
- They reduce BOM costs and encourage more widespread deployment of energy-measurement intelligence across the electricity value chain.
Key advantages:
• High performance: utility-grade sensing over the entire dynamic range of load current and power-down modes
• Reduced bill of materials (BOM) costs: internal RC oscillator and low baud rate serial interface eliminate the need for expensive and fragile crystals.
• Simplicity: firmware is optimized for end applications so design-in is greatly simplified.
