Voltage regulator, 40 A voltage stabilizer, surge protection, protection device

Function】: When overvoltage, undervoltage, or overcurrent occurs in the circuit, the voltage regulator can immediately cut off the power supply to protect electrical equipment from damage. When the mains voltage returns to normal, the protector automatically resets without any further manual operation.

【LCD Screen】: Dual display indicating overvoltage and overcurrent; the voltage status is clear at a glance, and the real-time display is clearer.

【PC Material】: The outer casing of the voltage protection device is made of high-quality PC material, which is flame-retardant and high-temperature resistant, with insulation protection, extremely low power consumption, and a long mechanical lifespan.
