12V 3A 36W Metallic Switching Power Supplies

12V 3A 36W Metallic Switching Power Supplies AlphaTronics by Alpha Elettronica represents a reliable and robust solution for those looking for a versatile power supply with a resistant metal body. This power supply is designed to offer effective protection against overloads and short circuits, ensuring safety and durability over time. Its ability to be easily connected via screw terminals makes it ideal for powering a wide range of devices such as LED strips, routers, hubs, security cameras and audio-video systems.

The specific recommendation of having a power supply with a rating of 20% higher than the actual wattage of the device it is connected to, ensures that there is always enough power without overloading the system. For example, for a 10W per meter LED strip, you need a power supply of at least 12W to ensure efficiency and reliability.

Technical features

  • High Protection : Included against overload, over temperature and short circuit, for safe and long-lasting use.
  • High Connection Versatility : Easy connection thanks to screw terminals, suitable for various types of electronic installations.
  • Power Regulation : Equipped with a trimmer for regulating the output voltage (±10%), it allows accurate control of the energy supplied.
  • Energy Efficiency : With a power factor of 0.5 and 1% load and line regulation capability, it optimizes energy use while reducing consumption.
  • Robust and Durable Design : Metal body with passive cooling, ideal for working environments from -20 to 40 °C, ensuring reliability even in extreme conditions.

These features make the 12V 3A 36W Metallic Switching Power Supply an excellent choice for industry professionals such as electricians and installers, as well as DIY enthusiasts who need a reliable, high-quality product for their projects.

Changed your mind? Here's what to do

If you want to return your order, we're here to help. You have the right to withdraw from the purchase within 14 days of delivery, without having to provide any reason.

Right of withdrawal (within 14 days)

The deadline is 14 days from delivery. If the order includes multiple items delivered separately, the deadline starts from the delivery of the last item.

The 14 days are calculated in calendar days, including Saturdays, Sundays, and public holidays. If the last day falls on a Saturday, Sunday, or public holiday, the deadline is extended to the next working day.

How to exercise it: Initiate the request from the dedicated function in your account: https://account.oniroview.com → Orders section → "Manage" → "Request Return". The withdrawal is validly exercised at the moment you send the online request; it is not subject to our prior authorization.

  • Return: You must send the products back within 14 days from the date you notified us of the withdrawal.
  • Refund: We will refund you within 14 days of the withdrawal notification. We may withhold the refund until we have received the goods or proof of their shipment, whichever occurs first.
  • Full withdrawal (you return all products in the order): 100% refund of the price plus standard outbound shipping costs. If you chose a more expensive delivery than the standard one at the time of the order, any supplement is not refundable.
  • Partial withdrawal (you return only some products): refund of the price of only the returned products; outbound shipping costs are not refunded. If the order benefited from free shipping due to reaching a threshold and the partial return causes the value to fall below that threshold, the corresponding shipping cost will be calculated and deducted from the refund.
  • Return costs: The direct costs of return are borne by the customer.
  • Diminution in value: You are only responsible for any diminution in the value of the goods resulting from handling other than what is necessary to establish their nature, characteristics, and functioning. In such a case, we will deduct from the refund an amount corresponding to the ascertained lost value.

The refund will be made using the same payment method used for the purchase.

Exclusions from the right of withdrawal

Pursuant to Article 59 of the Consumer Code, withdrawal does not apply to:

  • goods made to measure or clearly personalized (e.g., cables cut to size, custom configurations);
  • sealed goods that are not suitable for return for hygienic reasons or health protection, if unsealed after delivery;
  • digital content supplied on a non-material medium, if the performance has begun with your prior consent and acceptance of the loss of the right of withdrawal.

Outlet Items: Items in the Outlet category are sold as final sale and are not returnable.

B2B Sales: The right of withdrawal does not apply to contracts concluded with customers holding a VAT number.

How to ship the return

Once the request has been submitted, send all items to: Oniroview, Via Piave 17, 95129 Catania (CT), Italy.

  • Pack carefully and use secure, tracked shipping: products lost or damaged during return transit cannot be refunded.
  • To protect the original packaging, place it in a second box when possible. Do not apply labels or adhesive tape directly to the product's original packaging.
