High Voltage inside ,do not remove the cover. Professional installation of qualified electrician is highly recommended. 2.This product is suitable for indoor use, non-detachable power shell. External power supply round hole mesh heat vents, in the range of 50cm within the outlet Do not place other flammable items.5 cm in the product range not place other items, to ensure that the powersupply has good thermal environment, to ensure safety. 3.Before electricity use, carefully verify the power link is correct, rigorous power lines reversed. 4.Please accurately calculate the load power, do not overload.The 100W maximum rating for this LED driver must not be exceeded. 5.IN-DOOR USE ONLY! Review: Good power supply. Switch could be better. - So far so good, but a few minor things (not enough to subtract a star). Using to power a 16x16 LED matrix with an ESP 32. I tested the power supply with a multimeter and there is a 50ohm resistance across 5v V-/V+ which seemed a little odd, but is most likely due to shunt or bleed resistance. Tested at load and it was fine, with a stable 5.1 volt. The power supply came set to 110 v. However, the voltage switch is inside the chassis, and would be difficult to change if set to 220. You may be able to get an allen key in there, but it's probably best to take the case off if you have to change it. Not a huge deal, but not ideal either. Other supplies provide easier access. Review: Perfect 5V supply to power a rack of Raspberry Pi5's - I put together a small four-node PI5 cluster and wanted a single supply to power all of them. With the assistance of some USB-C power cables, this supply easily handled the cluster's power needs. Perfect supply for the price. ## Features - Switching Power Supply 5V, Convert AC 110V/220V to DC5V 20A Max,100 Watt Max.IN-DOOR USE ONLY! - Smart device surge protection for Short-circuit Protection, Overload, Over Voltage,Over Temperature Protection. High efficiency, High Reliability, Low Temperature Rise - Built-in EMI filter, low output ripple, noise, Rugged heavy duty enclosure, 100% Full load burn-in Tested. Parallel/Redundancy Operation is possible. - Good performance:mainly meterial are plastic and aluminum, which are good heat dissipation. The aluminum is carved directly, which make the transformer easier to heat dissipation. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07PQT2Q7L | | Best Sellers Rank | #42,061 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #172 in Power Converters | | Brand | Velain | | Brand Name | Velain | | Current Rating | 20 Amps | | Customer Reviews | 4.4 out of 5 stars 176 Reviews | | Item Dimensions D x W x H | 7.87"D x 3.94"W x 1.65"H | | Manufacturer | Velain | | Maximum Frequency | 60 Hz | | Minimum Frequency | 50 Hz | | Model | HDMI Splitter | | Mounting Type | Surface Mount | | Part Number | HDMI Splitter | | Power Source | DC | | Product Dimensions | 7.87"D x 3.94"W x 1.65"H | | Specification Met | CCC, CE, FCC | | UPC | 725756813123 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Velain - **Current Rating:** 20 Amps - **Mounting Type:** Surface Mount - **Power Source:** DC - **Product Dimensions:** 7.87"D x 3.94"W x 1.65"H ## Images ![5V 20A Power Supply,100W Universal Regulated Switching Power Converter Adapter Transformer for LED Strip Light,Probe Signal Lamp,CCTV, Radio, Computer Project - Image 1](https://m.media-amazon.com/images/I/61v5OvdkRxL.jpg) ![5V 20A Power Supply,100W Universal Regulated Switching Power Converter Adapter Transformer for LED Strip Light,Probe Signal Lamp,CCTV, Radio, Computer Project - Image 2](https://m.media-amazon.com/images/I/61Lns0EY8HL.jpg) ![5V 20A Power Supply,100W Universal Regulated Switching Power Converter Adapter Transformer for LED Strip Light,Probe Signal Lamp,CCTV, Radio, Computer Project - Image 3](https://m.media-amazon.com/images/I/71rlp504RXL.jpg) ![5V 20A Power Supply,100W Universal Regulated Switching Power Converter Adapter Transformer for LED Strip Light,Probe Signal Lamp,CCTV, Radio, Computer Project - Image 4](https://m.media-amazon.com/images/I/61KBaM63hoL.jpg) ![5V 20A Power Supply,100W Universal Regulated Switching Power Converter Adapter Transformer for LED Strip Light,Probe Signal Lamp,CCTV, Radio, Computer Project - Image 5](https://m.media-amazon.com/images/I/61oeypZi9bL.jpg) ## Available Options This product comes in different **Color** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good power supply.
