Compared to traditional meters, the new generation of smart meters have more convenient functions to help us know the total energy used by electrical equipment, tenant space or buildings anytime and anywhere. Smart meters have strict requirements for their internal power supply in order to achieve 24-hour online monitoring while achieving optimal safety standards.

Power Solutions for Smart Electricity Meter
|
|
|
Common Challenges and Demands
|
|
Save cost
|
Compact size
|
Excellent EMC performance
|
|
|
Wide input voltage：45-528VAC/90-528VAC
|
|
• Compatible with mutual inductor input：45-264VAC/45-528VAC
|
|
• Not compatible with mutual inductor：90-264VAC/90-528VAC
|
|
|
|
Transient power
|
|
• Data transmission requires high power(12V/0.56A), and the time is short within 3S
|
|
• If the design is based on long-term power, it will cause cost waste
|
|
|
|
EMI meets CISPR32/EN55032 CLASS B, surge meets ±2KV/±4KV
|
|
• Meet the EMC requirement with limited dimension & limited cost
