System Integration & Protection
Modular design supports N+1 hot backup and seamless capacity
expansion, enabling parallel operation with current sharing
imbalance ≤±3%. Equipped with standard RS485 communication
interface compatible with Modbus and TonHe dual protocols, enabling
"four-remote capabilities" (telemetry, remote signaling, remote
control, remote adjustment) for seamless automation integration.
Comprehensive multi-layer protection includes overvoltage
protection (320±5VDC), short-circuit protection, overtemperature
protection (automatic shutdown at 85℃ and restart at 80℃), and
overcurrent protection. LED digital display with key operation
supports three working modes (independent, manual, automatic), and
hot-swappable design ensures efficient maintenance.
Design & Environmental Specifications
Natural cooling design with compact structure weighing only 9kg.
Requires only good surrounding ventilation for stable operation.
Excellent environmental adaptability operates reliably in indoor
environments with temperature range of -10℃~+40℃, relative humidity
≤90% at 25℃, and altitude ≤2000m.
Applications
Widely used in various global scenarios including substations,
power plants, and power control equipment. Provides highly
reliable, efficient, and easy-to-integrate DC power supply
solutions for power systems, ensuring continuous and stable system
operation.
