Switch Mode Power Supply Transformer Calculations

Best solution for indoor power supply but could have put the transformer at the end not in the middle.

This cable is more than adequate for my needs. I use it as an auxiliary power supply off the NRG transformer I use for my Sony DSR-250. The only drawback is that it doesn't use heavy-duty cable. It's simply two-pole, almost zip-cord. I don't know how rugged it will prove to be.

Quality charger. Great display. To be able to access the 3 amp Quick Charge mode, you NEED a Quick Charge rated power supply of 18 WATTS. The instructions do not make this clear. Once I found the correct power supply, the Quick Charge mode as worked great.

It's a power supply.

I needed a way to control rack gear that had no on/off switch in their XLR power supply. Works well and switches are clearly labeled.

I purchased this switch to supply connectivity to an AP and 3 - IP security cameras in a detached garage. This 5 port switch is outdoor in its temp handling range. However it does need to be installed in a weatherproof enclosure or inside a building (with or without climate control.) It DOES NOT have stand alone power, but instead supplies POE power tto itself and downstream devices by being powered by POE into port 1. This means you need to power this with a POE switch or POE injector upstream. It can be powered by 802.3af or at POE, but for any practical install (meaning powering devices downstream of the switch) it needs fed with a 60W 802.3bt POE supply. I'm using a TP-Link 60W POE injector and this works without issue. The switch itself is a full feature Unifi switch. Configured and controlled via a Unifi controller (Cloud Key) it can be setup by a user with intermediate knowledge of networking. Ports feature full VLAN support and control. For my use case, I needed to power an access point and 3 wired cameras. The FLEX is tailor made for this. Port 1 is power in an a trunk port. Port 2 is a second trunk feeding and powering a Unifi 6 Pro AP. Ports 3, 4, and 5 are set to a camera VLAN as well as supplying power. It does get warm to the touch. It passes full line rate speeds. For those already in the Unifi ecosystem and in need of switch for hi/low temp environments, this switch is a good option. I'll update if anything changes or if there are any issues.

I use this intercom power supply in a studio setting. It is a two channel power supply that has a combine switch that allows the Technical Director to combine channels one and two into a single channel. I plugged it in and it worked clearly without static, hum or buzz. In other ways plug and play!!

These injectors give the PoE power supply required to use an Ubiquiti USW PoE switch that has 4 outputs. I power three G3-Flex cameras and an UAP-IW mesh on my roof to get adequate power.

Switch works fine, powered it with POE so one less wire but it does include a power supply if you need it. Wish it included a wall mount but that was easily obtained on ebay. There's a lot of people 3D printing them. Economy shipping went quicker than expected. Another easy to use unifi product.

Works just as easy as making the connections. Windows 7 - no problem. Short cut keys ( quick double tap of scroll then enter- and you switch between the two computers. You can have one set of speakers for both computers (the cables are built in). AS long as you have one connector to go from the monitor to their box ( same for keyboard and mouse) you are set. I am using DVI - and one computer is XP, the other is Win 7. I like the fact that it has it's own power supply. And if you use a master switch, you can put the power supply with that. My master switch goes to a UPS, so no worry there. Use it, you'll like it - and the one question I had was answered promptly by their tech support after a morning phone call. Couldn't ask for more.
