Introduction
EPC 48120 / 1800-HA (B) outdoor DC power cabinet integrates Emerson
outdoor protection cabinet and DC power system with reliable performance
and outstanding qualities to provide a stable and reliable operating
environment for outdoor communication equipment. In addition to the heat
exchanger, AC and DC power distribution, surge protection device, DC power
and battery chamber, the installation space for communication equipment is
also reserved in the system. The cabinet of high protection level and the
cutting-age temperature control design ensure the reliable operation of the
system in the adverse outdoor environment.
