4 FAQs about High Temperature Type Product Manual for Communication Power Supply Cabinets

How do you manage electrical component temperatures?

Managing electrical component temperatures can be accomplished in a variety of ways. One way is when air in the enclosure is exchanged with ambient air from the immediate surroundings; this is known as open loop cooling.

Can a telecom cabinet operate without heating and cooling?

Although the most rugged types of telecom equipment can operate without heating and cooling, most outdoor telecom cabinets are designed to comply with the GR-3108-CORE Class 1 specification, which requires that the internal temperature of the cabinet is maintained between 41°F (5°C) and 104°F (40°C).

Do Telecom cabinets need enclosure cooling?

The heat load of modern telecom cabinets is often high, and it's usually necessary to install enclosure cooling equipment to maintain the internal temperature below the higher limit specified by GR-3108-CORE. Enclosure heating may also be required in colder regions.
