Product Specification
Product Introduction
The STE38-G Three-Phase Prepaid Electricity Meter is a high-performance smart energy management device designed for commercial, industrial, and utility-scale power monitoring and billing. Compliant with international STS standards and IEC 62053-21, IEC 62052-11, and IEC 62055-41 specifications, this meter integrates dual-mode GPRS/433MHz RF communication with precise three-phase four-wire measurement technology. Equipped with premium international-grade metering chips, it delivers Class 1.0 measurement accuracy, ensuring reliable data collection and transparent prepaid energy management for businesses, industrial parks, and smart grid projects worldwide.
Crafted with a thickened flame-retardant shell and IP54 protection rating, the meter withstands harsh operating environments (-25℃ to 70℃) while ensuring user safety. Its modular plug-and-play design and back-mounted triangular hanging holes enable easy installation and maintenance, reducing long-term operational costs. Whether for remote energy monitoring, prepaid billing, or load optimization, the STE38-G is engineered to meet the diverse needs of modern power distribution systems.
Core Features
- Dual-Mode Communication: Supports GPRS and 433MHz RF connectivity for real-time data transmission, remote reading, and control via web portals, handheld units, or API-integrated platforms.
- STS Standard Compliance: Enables secure token-based recharge (20-digit token) with compatibility with global prepaid energy ecosystems.
- Precise Multi-Parameter Measurement: Monitors voltage, current, active/reactive power, four-quadrant energy, and neutral current for comprehensive energy analytics.
- Intelligent Prepaid Management: Features automatic switch-off when credit is exhausted, low-credit alarming, and bidirectional metering (ideal for solar hybrid systems).
- Enhanced Security: Equipped with tamper detection, cover opening detection, and Class II insulation protection (4kV AC insulation strength) to prevent theft and ensure data integrity.
- Flexible Tariff Setting: Supports up to 8 multi-tariff plans to adapt to time-of-use (TOU) billing models and energy conservation strategies.
- Reliable Performance: Operates at 50-60Hz with a wide voltage range (70%~120%Un) and low power consumption (<2W in voltage circuits), ensuring stability in extreme conditions.
- User-Friendly Design: Integrated LCD display, LED indicators, and infrared communication for on-site operation and data verification.
