Features: Zero offset, zero delay, with a top voltage-absorbing circuit to effectively protect high-power thyristors, offering anti-overvoltage, anti-spike, and RC absorption with multiple protections. The high-temperature resistant flame-retardant casing prevents deformation, and the metal spray paint resists rust, effectively guarding against high temperatures and pressures while eliminating potential safety hazards. Utilizes multi-functional industrial sockets with thickened copper internals for high current capacity, excellent contact, and safety. The humanized installation hole design allows for convenient flat placement or hanging. Independent button switch control provides free management of power supply and output interruption. Features exquisite, high-smoothness buttons for effortless operation, with output voltage clearly visible at your fingertips. Applications include high voltage, speed, temperature control, and thyristor dimming effects, suitable for household appliances, industrial electrical equipment, scientific testing instruments, and electrical equipment in factories and schools.
