24V 250W 10.5A Metallic Switching Power Supply
📐 24Vdc · 10.5A · 250W · IP20 · Metal housing · Screw terminals · 222×68×40 mm
🔧 Difficulty: 4/5 (230V and DC cable sizing) · 🎯 Ideal for: extensive LED systems, warehouses, multi-camera video surveillance
24V 250W 10.5A metal switching power supply for extensive systems
24Vdc switching power supply, 10.5A / 250W, with IP20 metal casing and screw terminals: the high-capacity size in the range, needed when an LED installation exceeds fifteen meters in length or when multiple low-voltage devices are connected to a single distribution point. 222×68×40 mm body, mountable vertically or horizontally.
Technical advantages
- ⚡ 10.5A available: powers extensive LED systems or multiple parallel branches without needing multiple units
- 🧱 Metal housing: at high power, heat dissipation matters, and metal dissipates via convection much better than plastic
- 🔩 Screw terminals: inspectable connection suitable for generous cable cross-sections
- 🔒 Integrated protections: overload and short-circuit
- 🔄 Dual mounting orientation: vertical or horizontal depending on the panel

Cable cross-section on the 24V side
At 24V, the current is ten times that of an equivalent 230V load, so the low-voltage cable cross-section becomes the true constraint of the project. Indicative values to keep the drop within 3%:
| Current on the branch | Up to 3 m | Up to 6 m | Up to 10 m |
| 3 A (72 W) | 1.0 mm² | 1.5 mm² | 2.5 mm² |
| 6 A (144 W) | 1.5 mm² | 2.5 mm² | 4 mm² |
| 10.5 A (250 W) | 2.5 mm² | 4 mm² | 6 mm² |
Expert Advice
🔍 Expert Advice:
At 250W, the nature of the project changes: the critical component is no longer the power supply, but the downstream cables. With 10.5A on a 24V backbone, a 0.75 mm² cable — which is perfectly fine for a 3A run — will heat up and consume half the voltage along the path: the strip at the end remains off and the cable becomes a safety issue. Use the table above and, when in doubt, increase the cross-section. Secondly, regarding the upstream side: switching power supplies of this size have high inrush current at startup, and if you connect two or three on the same line, a curve B miniature circuit breaker may trip without apparent reason every time the lights are turned on. In that case, a curve C breaker is needed. Alternatively, if the system is spread across different rooms, before buying a single 250W unit, consider two smaller units near the loads: shorter cables, cheaper cross-sections, and a fault that doesn't turn everything off.

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.
