We define the standards of metering through the depth of our technology.
JND Electrolex sets a new standard for smart metering in South Korea.
JND Electronics independently implements the core technologies that open the future of KEPCO AMI 2.0 in Korea. From the design to the manufacturing of AMIGO secure smart meters, we manage the entire process in-house and are leading a new era of smart metering in the Republic of Korea.
Our technological foundation is built on long-standing experience in the stable supply of AE and G-type energy meters. Based on this deep expertise and trust, JND Electronics, through joint R&D with KEPCO, has driven innovation in the “heart of metering” – the current transformer (CT) for power supply and demand. As a result, we developed a unique live-installation split-core CT, a breakthrough solution that transforms installation practices in the field and stands as clear proof of JND’s technological leadership.
On top of our high-efficiency AC/DC converter technology, which underpins stable measurement performance, we have integrated built-in power quality (PQ) analysis capabilities that precisely diagnose the grid. In doing so, we go beyond simple measurement to deliver true “Metering Intelligence”.
The culmination of all these technologies is rooted in JND’s principle of “complete technological internalization.” JND Electronics has established a true one-stop production system that encompasses the entire lifecycle of technology: Design, where ideas are born; Development, where they are realized and refined; and Manufacturing, where they become final products. By operating the full process under a single point of responsibility, we ensure rapid, field-driven improvements and a stable, uninterrupted supply.
From in-house manufacturing capabilities for key components, to field-transforming innovative CT technologies, and fully vertically integrated system-level solutions, JND Electronics becomes your most reliable technology partner at the grid edge, continuously raising the standard for smart metering and smart grid infrastructure.

JUMPSTART
We set new standards with a bold first step.
Through in-depth analysis, advanced engineering, and creative execution, we are the first to turn the potential of grid-edge metering into real products. With AMIGO secure electronic energy meters for KEPCO AMI 2.0 and in-house CT technology, our speed and completeness in setting new standards define our competitive edge.
NEXT-GEN
Technology leadership that designs the standards of tomorrow.
We design the next-generation KEPCO smart metering (AMI 2.0) standards based on the real needs of utility field operations. AMIGO energy meters carefully integrate built-in PQ (Power Quality) analysis and standard communication interfaces such as RS-485/Modbus. Combined with high-efficiency power supply design and live-installation split-core CTs, they simultaneously enhance accuracy, reliability, and operational efficiency.
DARING TO DEFINE
Defined by action, proven by data.
We do not remain bound by convention. Through real-world demonstrations and data-driven validation, we quantify and prove every performance gap, using the results accumulated in the KEPCO AMI 2.0 (AMIGO) project to define the next-generation smart metering standard.
JND Electronics, true to the philosophy in its name, is a specialized provider of AMIGO secure electronic energy meters (smart meters) for the KEPCO AMI 2.0 era. Building on extensive experience in the stable development and supply of Advanced-E (AE) and G-type electronic energy meters, we have integrated innovative, high-efficiency AC/DC power technologies to further enhance reliability and long-term stability.
The Value We Create
We manufacture the core component of smart metering, the current transformer (CT) for power supply and demand, fully in-house. With our live-installation split-core CT design, we minimize installation downtime and safety risks. By combining built-in PQ (Power Quality) analysis, field-standard communications (RS-485/Modbus), and RTOS-based operation, we deliver the accuracy, interoperability, and operational reliability required in modern utility environments.
Proven Reliability (Label-Level)
- Standards / Certifications: UL, CE (MID), ISO 9001 / 14001 / 45001
- KEPCO References: Qualified approval and type certification (multiple models), seamless AMIGO migration based on AE and G-type deployment track record
- Key Standards Compliance (Summary)
- Power-supply CT: KS C 1707, IEC 61869-2
- Metering unit: IEC 62052-11, IEC 62053-21 / -22 / -23 and relevant IEC/ANSI requirements
Growing the Ecosystem Together
In collaboration with domestic and global HES/MDMS cloud partners, we support API integration (MQTT/HTTPS) and secure remote metering based on TLS 1.2+ and OAuth2/PKI. This strengthens data integrity between the field, the cloud, and AMI 2.0 back-end systems, unlocking the full value of the next-generation grid-edge.
