Features This is a non-isolated DC power converter module with long service life, and the range of adaptive current and voltage is large. it covers from DC-DC 10-60V to 12-97V. High power and stable output, practical and easy to install. The power supply module uses double sendust magnets winded with 1.2mm copper wires. Designed with smart temperature control fan, which will automatically work according to the temperature. The process of usage can avoid burning, so the use of electrical appliances have better satety, and users have a more secure experience, Features:This is a non-isolated DC power converter module with long service life, and  the range of adaptive current and voltage is large. it covers from DC-DC 10-60V to 12-97V.High power and stable output, practical and easy to install.The power supply module uses double sendust magnets winded with 1.2mm copper wires.Designed with smart temperature control fan, which will automatically work according to the temperature.

Instructions: Under voltage adjustable range:DC10V‑50V (clockwise to increase, counterclockwise to reduce), firstly adjust under‑voltage to the minimum, then adjust input voltage to required under‑voltage protection value, slowly adjust under‑voltage value clockwise to increase; when the under‑voltage light is on, adjust counterclockwise of one circle, then power on again. Input under‑voltage protection mainly used to prevent battery from over‑discharging when input power source is battery. Low battery voltage will damage power module and battery. When input is switching power supply, it also need to set the low voltage protection. Constant voltage adjustable range:DC12‑97V(clockwise to increase, counterclockwise to reduce), first adjust voltage to the required voltage and then connected to the load. Package List
