Overvoltage protection: guards connected equipment from voltage spikes and surges, helping prevent damage and keep operation stable. Overcurrent protection: limits current to safe levels, reducing the risk of wiring damage, component stress, and fire hazards. Overtemperature protection: detects excessive heat and takes protective action to prevent thermal damage and maintain performance. LCD display: dynamically shows realtime operation data and the working status of the equipment for quick monitoring and diagnostics. User adjustable controller parameters: some controller settings can be modified by the user and saved for repeatable configurations. Key benefits Enhanced safety for power electronics and wiring, reducing the chance of unexpected failures. Realtime visibility into system status without external tools. parameters to suit different equipment and processes. Use scenarios Benchtop lab power supplies and test rigs: protect sensitive electronics during experiments while providing clear status readouts. Small to midsize automation projects: safeguard motors, sensors, and controllers, with quick checks via the LCD and configurable parameters for different runs. Renewable energy and energy storage setups: stable protection and adjustable settings to optimize charging, discharging, and system monitoring.
