Reliability
Accuracy remains stable over extended periods; requires no periodic recalibration and is unaffected by installation or transportation stresses.
Accuracy
Features a wide measurement range, broad power factor adaptability, and high startup sensitivity.
Functionality
Supports centralized meter reading, multi-tariff billing, prepayment systems, anti-theft measures, and meets requirements for internet connectivity services.
Cost-Effectiveness
Offers excellent value for money, includes reserved capacity for future functional expansion, and is minimally affected by fluctuations in raw material prices.
Alarm Notification
When the remaining credit falls below the preset alarm threshold, the meter continuously displays the remaining balance to prompt the user to purchase electricity. When the remaining credit reaches the alarm threshold, the meter trips once to interrupt power supply; the user must insert their IC card to restore power, at which point they should promptly purchase additional electricity.
Data Protection
Data protection is implemented using fully solid-state integrated circuit technology, ensuring that data remains preserved for over 10 years, even in the event of a power outage.
Automatic Power Disconnection
When the remaining credit in the meter reaches zero, the meter automatically trips to interrupt the power supply; the user must then promptly purchase additional electricity.
Data Write-back Function
The electricity card can write back the user's cumulative consumption, remaining credit, and "zero-crossing" consumption data to the electricity sales management system, facilitating statistical analysis and administrative oversight.
User Sampling Function
The electricity sales software supports data sampling of consumption levels and can generate a prioritized list of users for inspection based on specific requirements.
Consumption Inquiry
Upon insertion of the IC card, the meter sequentially displays the total purchased electricity, number of purchase transactions, amount purchased in the last transaction, cumulative consumption, and remaining credit.
Overvoltage Protection
If the actual electrical load exceeds a preset safety threshold, the meter automatically trips to interrupt the power supply; inserting the user's card restores power.
