Can a power supply be used outdoors?
Power supplies used outdoors on top of buildings, traffic lights and other external urban small cell locations also need to be able to withstand the rain and dampness. Mostly, this will involve placing power supply units inside waterproof cabinets creating a “semi-outdoor” environment.
What are the requirements for a power supply unit?
Power supply units feeding the cell site gateway, aggregation routers, and core routers need to be able to operate outdoors or semi-outdoors, withstand wide temperature variation, and offer surge protection. There are also requirements for the mobile core itself - usually indoors or inside a container.
What makes a good power supply?
This includes: R&D capability to provide a standardized and intelligent power supply. For instance, products with digital and communication functions, high power density, high efficiencies, designs that can withstand harsh conditions, and highly scalable systems for wider roll-outs. Digitized product design.
Should you use a MOSFET with a power supply?
Pairing them with integrated power supply devices costs more, but it also protects small cells if there are dramatic changes in voltage. For instance, FETs can dissipate power and stabilize the differences between input and output voltages. They also use thermal control features to keep the internal power MOSFETs with a safe operating range.
How do dust-proof power supplies work?
Dust-proofed power supplies have solid metal cases, sometimes coated in heat-conducting silicone gel. To keep dust out, they do not use fans. Instead, they rely on passive cooling technologies that help to dissipate any excess heat out of the chassis and into the wider environment.
Do adaptors and power supplies have overvoltage protection?
Adaptors and power supplies with overvoltage protection, however, can mitigate these risks. Several types of overvoltage technologies are available. One of the most common is the SCR crowbar. Here circuits use thyristors to link back to a fuse that blows, isolating the circuit and protecting the equipment.
