Description
【Upgrade ac to dc converter】Compared with the old power supply, we have retained 3 sets of output channels, but upgraded the input channels. The old power supply needs to be connected to the input through wiring. We have upgraded the input method, greatly improving the connection efficiency. In addition, we have added a safety switch, which can more conveniently start or turn off the power supply. On the other hand, the safety switch can also be used to quickly determine whether the power supply is normal
【12 Volt Power Supply】Input voltage 110v-240v ac, output voltage 12v dc, adjustable range: ±10%; Output current Mainly depends on your decive, such as DC 10A/120W, 20A/240W, 40A/480W, max current up to 40A, max output power 480W, For more efficient and secure use, recommended for equipment below 384w
【Intelligent Cooling System】The 12v 40a power supply with aluminum alloy shell and designed with multiple holes for better heat dissipation, Built-in intelligent Cooling Fan to prevent overheating and burning of circuit boards, when the working temperature is more than 122℉(45℃), the power supply will automatically run to dissipate
【Multiple Protection】BOSYTRO 12v switching power supply features a overload protection, over-current protection, short circuit protection which can protect your device from damage. Safe and stable, suitable for newer or an experienced user
【Wide Application】This 12v dc power supply widely used in industrial automation equipment, RV, radio/car stereos, led strip, cctv, computer project, 3d printer, motor pump, security camera, lcd monitor, lab computer and more 12 volt device

Common questions about buying open-box and refurbished.
Why buy refurbished or open-box?
Refurbished and open-box products offer the same performance as new at a fraction of the price. You're already saving $3 on this listing. They've been inspected, tested, and are ready to use — the only difference is the price tag. Buying refurbished also reduces electronic waste, extending product life cycles and keeping functional devices out of landfills.
What's the difference between open-box and refurbished?
Open-box products are customer returns that have been inspected and confirmed functional. They may show little to no use — often the item was returned simply because the buyer changed their mind. Refurbished products have been professionally repaired or restored by technicians, tested to meet or exceed manufacturer specifications, and sometimes come with a warranty. Both are a smart alternative to buying new.
Why use OpenBoxFox?
Finding refurbished deals is time-consuming — you'd have to check Amazon Warehouse, Reebelo, Dyson Outlet, and others separately for BOSYTRO products. OpenBoxFox aggregates these listings in one place, so you can compare and find the best deal without the legwork. We update pricing daily so you always see current availability and real savings.
Is it safe to buy refurbished?
Yes. Products listed on OpenBoxFox come from established retailers like Amazon, Reebelo, and Dyson — not unknown third-party sellers. Each retailer has buyer protection policies, return windows, and in some cases warranties. You get the price advantage of used goods with the purchase security of a known retailer.
