The company's EV charger mainboard modules are optimized for DC fast charging, integrating surge protection up to ±6.5kV and low-power design, making them ideal for high-reliability scenarios such as public charging stations and commercial complexes. The company also provides comprehensive metering solutions for EV charging billing, helping customers build efficient and reliable smart charging infrastructure.
3. Smart PDU Meter Modules
For data centers and industrial power distribution, Jiansiyan's PDU metering modules offer real-time energy monitoring, remote management, and overload protection. These compact modules support Modbus - RTU ,SNMP V1/V2c/V3 and other protocols, making them an ideal choice for data centers aiming for refined energy efficiency management.
4. IoT Smart Meters
WiFi-based smart meters are another highlight of Jiansiyan. These meters support remote meter reading, energy consumption analysis, and can be integrated with smart home systems, helping users monitor household electricity usage in real time to save energy.
5. Other Product Areas
Jiansiyan's business also covers:
Electrical measuring instruments and meters: Professional single/three-phase electrical parameter measuring instruments.
Fire alarm and fan control systems: Fire protection products such as the JSY-MK-310M.
Energy consumption analysis and split-phase energy metering systems.
Smart gateway devices as data hubs for IoT systems.
Business Model: Dual-track Development Driven by Technology
Independent R&D and Technological Innovation
Jiansiyan always considers technological innovation as its core driving force. According to the company, more than 50% of its products are technology-innovative products, leading the industry.
