Power Description
2 Product Overview
Power 6308 converts AC power to –48 V DC power. It is part of a modular building concept that enables a variety of
installation alternatives that can be expanded. Flexible mounting solutions are provided using rails, pole clamps, and
brackets. The small size together with the flexible mounting solutions reduce the site volume. The low weight also provides
easy handling.
2.1 Main Features
These are the main features of Power 6308:
– Converts AC mains (100–127 V AC or 200–240 V AC) to −48 V DC voltage to feed remote radio products
– Has a total output power of 3500 W peak and 3000 W average at 100–127 V AC, and 6000 W at 200–240 V AC
divided across seven output ports
– Has a similar appearance as a Radio 4480 and uses the same type of handle and rail mounting bracket
– Has an IP65 enclosure
– Is convection-cooled
– Protects against power line disturbances and lightning
– Can handle a current ripple load of 80% of full output power and limit the voltage ripple to a level suitable for the
radio
– Uses Support Unit (SU) communication to the Radio
– Can be connected in parallel with another PSU for redundant operation
– Has two integrated battery ports

3.2 Environmental Characteristics
This section contains operating environment data for Power 6308.
Power 6308 is designed to be installed in a Class 4 environment.
Power 6308 must be installed in restricted access locations, such as building rooftops or poles where the general public has
no access.

(1) For high ambient temperature, > 45°C, an inherent movement of air is expected. The unit must therefore be installed so that free movement of air is
allowed around it.
3.2.2 Heat Dissipation
The unit is convection-cooled and intended for rail installation. The heat dissipation of the unit can be calculated by using
data in Power Consumption Data.

5 Installation Recommendations
To achieve reliable operation and maximum performance, an appropriate installation location must be chosen.
5.1 Indoor Locations to Avoid
Although the unit is designed for outdoor use, it can also operate in an indoor environment according to ETSI EN 300 0191-3 class 3.1, 3.2, 3.3, and 3.6. This does not include installation with heat traps or installation in lofts, where air ventilation
does not exist. For smooth performance of the product, it is recommended to ensure that the planned installation site for
the unit is not a potential microclimate location. This typically occurs in locations such as unventilated lofts, sites with heat
traps, or sites where the product is exposed to direct sunlight through windows. Ensure proper ventilation and avoid
installing the equipment below glass covers or skylight windows.
5.2 Outdoor Locations to Avoid
Although Ericsson declares this product suitable for most outdoor environments, this does not include installations where
the planned installation site for the unit is a potential microclimate location. Typical examples of these microclimate
locations are sites where the product is not only exposed to the actual temperature, but also additional heat is generated
from dark-colored planes, for example, reflections from the ground or walls. The additional temperature can generate heat
traps with temperatures up to 10°C higher than expected.
Avoid to install equipment in the following locations:
– Near the exhaust of a building ventilation system
– Near the exhaust of a chimney
– Opposite large surfaces made of glass or new concrete
5.3 Painting Limitations
Ericsson does not recommend to paint the unit as it can affect the performance of the unit. If the unit is painted, limitations
to the warranty and service contract will apply.
5.3.1 Technical Limitations
If the unit is painted, be aware of the following technical limitations:
– Sunlight on dark paint may increase the temperature of the unit, causing it to shut down.
– Never use metallic paint or paint containing metallic particles.
– Ensure that ventilation and drainage holes are free from paint.
– Ensure proper adhesion of the paint.
5.3.2 Commercial Limitations
If the unit is painted, the following commercial limitations apply:
– Failure modes directly related to overheating due to painting are not valid for repair within the scope of the warranty
or standard service contract.
–
about:blank
12/23
2/8/24, 9:34 AM
Power Description
Product failures related to paint contamination of components of the unit are not valid for repair within the scope of
warranty or standard service contract.
– When a painted unit is repaired, it will be restored to the standard color before being returned to the market. It is not
possible to guarantee the same unit being sent back to the same place. This is also valid for units repaired under a
service contract.
– For repairs within the warranty period or a standard service contract, the customer will be charged the additional
costs for replacing all painted parts of the unit or the complete unit.

The equipment presented in this section is optional and can be ordered separately.
6.3.1 DC Fuse
Each DC output interface of the unit supports one DC fuse. Select the DC fuse according to the power consumption and
cable size of the load equipment. The fuse quantity must correspond to the number of the load equipment. The fuses are
class G type designed according to UL 248-5. These are the available fuses:
