Features 【FEATURES】: This is a non-isolated DC power converter module with long service life. Input overcurrent protection; Short circuit protection; Input reverse connection protection; Low battery protection. 【DIY PROJECTS】: It adopts 7 electrolytic capacitors and a 33MM high-power iron-silicon-aluminum magnetic ring to prevent over-temperature magnetic saturation under high current conditions. Use a piece of aluminum radiator on the back to dissipate heat , Reserve fan mounting holes, suitable for more DIY projects. 【WIDELY APPLICATION】: Can be used for high power solar street lamp driving, various LED lighting CV driving, vehicle-mounted and mobile device power, DIY adjustable CV CC power, solar power charging, and various batteries charging. 【ADJUSTABLE VOLTAGE】: 1200W 20A DC converter boost Input voltage range is DC 10-60V, Output voltage range is DC 12-80V. Can be arbitrary adjustable; Input current: 0.5-20A (MAX), Max output power is 1200W.(exceeds 15A, please add fan cooling）High power and stable output, it converts 10-60VDC to 12-97VDC. 【OUTPUT POWER】: Input voltage * 20A, such as: input 12V * 20A = 240W, input 24V * 20A = 480W, input 60V * 20A = 1200W Note: Do not use the short-circuit output method to adjust the current. It is recommended to use a smaller adjustment range. High quality components ensures high conversion efficiency, up to 97%. Features: The product is a hand planer, used to plan wood, gypsum board, etc., can be used as trimming, and is a tool for craftsmen. SK5 blade: This product adopts SK5 blade, which has high hardness, sharp cutting edge and long service life. 45°/90° trimming: There are double grooves, one groove is a 90° right angle, and the planing surface is 45°. The right angle side can be cut into a 45° bevel; the other groove is a 15mm wide 180° flat angle, Can be cut out at right angles. Reusable: The product can be used multiple times, with good quality and long service life. If the blade is no longer sharp, you can replace it with another blade. Small shape: The product shell is made of ABS engineering plastic, which is of good quality, lighter in weight, and small in size, which is convenient to carry and use. Application range: Mainly used to trim the corners or planes of gypsum board, fiberboard, cork board, etc.  Specifications: Product material: ABS+metal Product color: yellow Planing angle: 45°/90° Suitable length of flat-angle planer: ≤15mm Package weight: 125g Packing size: 15*6*3cm   Packing list: Hand planer*1 Package List
