Dc Voltage Controlled Switch

[Hardwired] I maintain a remotely controlled EMS radio site that is deep in a national forest. Power there is either too low a voltage, or too high, and rarely correct. The LCR2400 does a great job in compensating for the changing voltage, and protects about $40K worth of radio equipment. It has worked 24/7 for over two years with no problems. Highly recommend it !!

[24 VDC, 5.0 A] I purchased this power supply to power up the STM-1. Just be aware that you have to cut the DC plug end off to connect it to the STM products. I used my VOM to make sure I had polarity correct and then wired it to the STM-1. If you look at the STM-1, and possible the other STM products, this power supply gives the full voltage for the preamp to work at the designed level. If you use a power supply less than what this supplies, the STM does not provide as much of a preamplified signal. Work fine. Get it if you do already have another voltage source for the STM products.

[OLED] Literally Plug & Play. A simple robust way to run a simple low voltage on/of switch for a cabinet of equipment.

[15 W] This switch has become a staple in telecom hut and cabinet deployments for my company. It not only can be powered by DC and/or AC, it supports power options that make it effectively a hardened unit. I particularly like that I can power it natively with DC connections without the need for a large power adapter. When connected to our DC power plant, it is backed up by multiple 185AH -48V battery strings, keeping our PoE powered cameras, access points, and environmental monitors operational, even during loss of utility power. Eight ports is perfect for this function. The UNMS management platform is easy to use and allows us to manage each site from one pane of glass. The only drawback is that it doesn't come with rack-mount ears to support 19 racks. This isn't enough of a con to subtract a star, though. We have been able to adapt. While using the short metal bracket that comes with the switch on one side, we use a 3D-printed bracket on the other side that works perfectly for 19 racks. Overall, this PoE switch is vital to the success of my department and allows us to maintain an uninterrupted eye on each site, wireless access for field technicians at the site, and environmental monitoring, even when the power goes out.

[Camouflage] Great for controlled lighting

[Gray] Compact plate for DC out.

[Black] Perfect, the flexibility of voltage is great!!!

[1] Works as it should on AC power. Have not tried it on DC.

[30 W, 4 A] Great to have DC out on a Sony battery
