Part 3: Built-in Protection Systems
Over-voltage protection automatically shuts down output if voltage exceeds 40V. Over-current protection activates at 1100A to prevent damage. Short-circuit protection triggers immediate output disconnect. Thermal protection with fan cooling ensures stable operation up to 50 degrees Celsius ambient. All protection parameters are user-configurable via the digital interface.
