Dual LCD digital display allows real-time monitoring of output voltage and battery voltage. Fault detection with ble and visual alerts on the display screen for conditions such as battery under-voltage, over-voltage, overload, high operating temperature, and output short circuit. Overload delay shutdown function helps prevent false triggering during startup of motor-driven appliances. Includes reverse polarity protection for positive and negative terminal connections, suitable for small power non-professional user applications. Equipped with an intelligent temperature-controlled cooling fan for efficient heat management, ensuring quiet and energy-efficient operation. Digital MCU control delivers stable output waveform, precise frequency, accurate output voltage, and fast-acting protection circuits. Designed for use in vehicles, boats, mobile stations, telecommunications, public safety, and emergency equipment.
