Standards

The QSM31-2 is a robust three-phase smart meter. It supports prepaid and postpaid billing simultaneously, pairing accurate metering with all-round energy and network monitoring tools. Built-in functions including multi-tariff control, load profile archiving, event recording and tamper sensing allow service providers to streamline operations and secure stable revenue. Thanks to modular communication interfaces and an expandable system framework, the QSM31 flexibly caters to ever-changing AMI, smart grid and energy management standards.

Complying with STS standard: Designed with a robust, integrated tactile keypad built directly into its specialized dustproof housing, facilitating compliant token-based vending operations directly at the mounting site.
 It manages sudden load demand shifts and executes automated tariff disconnections based on continuous, real-time localized credit evaluations.
Comprehensive Tamper & Maintenance Security: Specifically optimized for field-durability with an externally accessible, replaceable battery that ensures continuous display functionality and uninterrupted event logging for base/terminal cover open detections during absolute power blackouts.
