The XZ188 Integrated Single Phase Prepaid Energy Meter is a high-performance smart metering solution designed for residential, commercial, and utility prepaid electricity applications. Featuring STS prepaid technology, DLMS/COSEM compliance, advanced tamper detection, and AMR/AMI communication capability, the XZ188 provides accurate energy measurement, secure credit management, and reliable operation even in harsh environments.
Built in a compact BS8565 standard housing, this keypad-based prepaid meter supports a wide dynamic current range from 5A basic current up to 80A maximum current, while maintaining excellent RF immunity and an IP54 protection rating for outdoor and industrial installations.
Supports STS (Standard Transfer Specification) prepaid technology
Enables convenient electricity credit management through keypad operation
Supports prepaid mode and credit mode hot swapping
Automatic disconnection when credit is exhausted or overload occurs
DLMS/COSEM compliant for smart grid applications
Supports PLC/RF communication with AMR/AMI head-end systems
IEC62056-21 compliant optical communication port for easy data reading and interrogation
Supports Time-of-Use (TOU), multi-tariff, and holiday settings
The XZ188 provides intelligent monitoring and records abnormal events, including:
Cover opening detection
Reverse connection detection
Significant Reverse Energy (SRE) detection
Power outage event recording
Tamper event logging
