The term "AC outdoor telecom cabinet" may refer to different configurations. One case is a cabinet with AC input, power distribution, and protection components inside; another is a cabinet equipped with an AC air conditioner or other AC cooling units. Both products differ in electrical layout, heat dissipation, cable entry, and maintenance requirements.

Before customization, confirm the input voltage, frequency, power distribution, air conditioning or climate control equipment, internal telecom gear, and cable entries. If power modules, telecom equipment, and batteries are installed simultaneously, thermal evaluation and internal zoning are also required. This article explains how to distinguish between AC power supply and AC climate control configurations to prevent misunderstandings.
