DISTRIBUTION FEEDER TERMINAL FTU YM-FDR700

YM-FDR700 Distribution Feeder Terminal (FTU) is developed per the 2021 Standardized Design Scheme for 12 kV Primary-Secondary Integrated Pole-Mounted Circuit Breakers and Distribution Automation Terminals. Featuring a high-performance, fully domestic processor, it enables monitoring and protection of distribution networks for safe, reliable operation. Key functions: three-stage protection, zero-sequence current protection, overvoltage/undervoltage protection, reclosing, single-phase ground fault protection, data acquisition/processing and remote transmission, remote signaling anti-jitter and error prevention, SOE recording, remote control logging, line loss logging, protection logging, terminal operation logging, control loop disconnection detection, self-diagnosis, self-recovery and abnormal alarms, non-blocking lockout, inrush current anti-misoperation, local FA protection, post-acceleration protection, fault/ switching/ energy storage waveform recording, and State Grid encryption.

STACKABLE HOME ENERGY STORAGE SYSTEM YM-B400

Yunmu Home Energy Storage System is a new-generation modular vertical stacked all-in-one unit with layered inverter and battery architecture: the 6.2 kW inverter module integrates MPPT, bidirectional conversion, and UPS switching; the 5 kWh LiFePO4 battery pack serves as the standard module, supporting vertical stacking and expansion. The core innovation uses aviation connectors instead of cables for one-step alignment, offering high current capacity, vibration resistance, mis-insertion prevention, and long service life, significantly reducing installation time and wiring faults. Wall-mounted vertical design with BMS-inverter collaboration ensures excellent balancing and fault isolation; compatible with grid-tied/off-grid modes, suitable for PV storage, backup power, and demand response, enabling flexible capacity expansion in limited space while balancing performance, safety, and maintainability.

DISTRIBUTION TERMINAL UNIT DTU YM-D800

YM-D800 Distribution Station Terminal is widely used in switching stations, distribution rooms, ring main units, and box substations for local detection, control, and fault current detection of switchgear. Working with master/sub-station systems, it enables multi-line measurement, control, fault detection, location, and zone isolation, reducing outage areas. Integrating protection, measurement, and line loss statistics, it meets the latest State Grid primary-secondary integration requirements. Featuring a high-speed DSP core and highly integrated design with industrial-grade components, it offers high reliability in harsh environments, rich plug-in expansion, self-check/mutual-check alarms, smart terminal data access and forwarding, isolation protection, and strong EMI resistance.
