Products information

The STE38-GS GPRS Three-Phase Prepaid Split-type Electricity Meter is a high-performance device tailored for commercial and industrial power management, consisting of a prepaid keypad meter and a separate Customer Interface Unit (CIU) with the CIU equipped with an RF communication module that provides a coverage range of 300 to 400 meters. It features precise three-phase four-wire system measurement, allowing for real-time access to electricity data such as voltage, current, active/reactive power, and four-quadrant energy via web portals, handheld units, or API-integrated platforms. Compliant with STS standards and equipped with international-grade metering chips, it ensures accurate measurement and reliable prepaid management, while its modular plug-and-play design not only adapts to various smart metering needs but also maintains compliance with data collection and network communication requirements. With the RF module enabling remote on/off control and data synchronization, and a component-replaceable architecture that reduces long-term costs, this meter is perfectly suited for applications in industrial parks, commercial complexes, and large public facilities, serving as a key tool for intelligent power distribution and consumption optimization.
