1.Quality material adopted and stable output, small volume, low weight, easy to carry and move and simple operation. 2.The power supply has an overcurrent setting and an overvoltage setting, so that the product is not damaged by short circuit when using the power supply. Safe and convenient. 3.The power supply is sturdy and compact. Productive work, as the power supply provides multiple protection functions for overvoltage, overcurrent, overload, overtemperature and short circuit. 4.Applied in production line testing, electrical maintenance, aging products, battery charging, scientific research and teaching in laboratories and all others who need a DC regulated power supply. 5.The power supply is durable and compact. Productive work, as the power supply has multiple protection functions against overvoltage, overcurrent, overpower, overtemperature and short circuit. 6.Used in production line tests, electrical maintenance, aging products, battery charging, in laboratories, in scientific research and teaching and anywhere where a regulated DC power supply is required. 7.By using quality material, the performance is more stable, the volume is small, the weight is low, it is easy to carry and move and the operation is simple. 8.The DC bench power supply can effectively dissipate heat. Reduces operating noise and extends the life of the equipment.
