"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.
