About this item:
New upgrade: variable voltage fan speed controller, the input voltage is AC 120-220V, the output voltage is adjustable from 0-220V, the maximum power is 4000W, the rated current is 9A and the limit current is 15A
Good quality: zero hysteresis, zero delay, with peak voltage absorption circuit to effectively protect high-power thyristor, anti-surge, anti-peak, RC absorption multiple protection. The flame-retardant metal casing does not deform under high temperature, and the metal spray paint does not rust, which is resistant to high temperature and heavy pressure
High safety: This voltage regulator adopts imported high-quality chip thyristor, high-power new semiconductor, all-aluminum heat sink, high-temperature-resistant FR-4 circuit board, and double-sided copper-platinum welding is safer and firmer. The multifunctional industrial socket is adopted, and the internal copper parts are thickened phosphor bronze fittings, which have good contact and safety
