Technical parameters of low voltage power supply / student regulated power supply

Low voltage power supply / student regulated power supply Model: HAD/SJ-18C

I. Overview HAD/SJ-18C low-voltage power supply is mainly used for high-grade dedicated low-voltage power supply for teaching and research in institutions of higher learning, secondary specialized schools, various professional technical schools, and advanced vocational middle schools.
The power supply implements the national education industry standard, the product is completely stable in performance, the adjustable gear position is reasonable, the ripple voltage is small, and the anti-interference ability is strong. The instrument has no overload automatic protection device, and the use is extremely convenient and reliable.
