Comprehensive Protection Design, Ensuring Safety and Reliability

Equipped with transformer short-circuit protection and interturn short-circuit protection functions. When a fault occurs, the LCD screen will directly display alarm information to timely avoid equipment damage risks.

The equipment shell and grounding terminal must be reliably grounded, and high-voltage and low-voltage cables are clearly distinguished to avoid dangers caused by reverse connection, ensuring operational safety. Adapts to working temperature of -20ºC~40ºC and relative humidity ≤85%, usable both indoors and outdoors, and can resist slight interference with strong stability. Equipped with 1A test fuse and 2A power fuse, double protection for circuit safety, reducing the impact of sudden faults on the equipment.
