Key points of selection of 24V inverter power supply for base station

Most friends who do communication base station operation and maintenance and engineering procurement have encountered this kind 

of headache: AC equipment such as monitoring and transmission in the base station will be shut down as soon as the mains supply is in-

terrupted, and the 24V battery pack that comes with the base station cannot directly supply power to the AC equipment. A separate UPS 

takes up cabinet space, and the cost is much higher. Especially in remote outdoor sites, the temperature difference between winter and 

summer is large, and the dust and humidity are heavy. It won't take long for ordinary civil inverters to break down, and it takes time and 

effort to run back and forth for on-site maintenance, which also delays the operation and maintenance progress.

Many people think that the inverter is a simple voltage conversion device. Just choose a device with similar power. When it is really used 

in the field, it is found that either the equipment is disconnected in time or the outdoor environment is frequently damaged, which adds 

more trouble. We have been deeply involved in the field of industrial power supply for many years, and have provided power supply for 

hundreds of communication base stations and outdoor monitoring stations. After contact, we found that choosing the right 24V inverter 

to adapt to the scene can not only control the cost, but also greatly reduce the pressure of daily operation and maintenance.

When choosing an inverter for a base station scene, it must first fit the power distribution system at the scene. The backup batteries of 

mainstream base stations in China are all 24V DC system, so the special models corresponding to 24V DC input and 230V AC output are 

directly selected, which can be used directly by connecting the batteries without additional transformation of distribution lines, and the 

installation and debugging can save a lot of things. Like our 2KVA rack communication inverter, it is a standard 24V DC input, which pe-

rfectly adapts to the original battery pack of the base station and can be deployed quickly without additional wiring.

The continuity and stability of power supply are the core requirements. The transmission and monitoring equipment of the base station 

cannot be powered off casually, and the inverter must support the seamless automatic switching between the mains bypass and the in-

verter mode. When the commercial power is normal, it bypasses to supply power to the load, and at the same time, it intelligently floats 

and maintains the battery. When the commercial power is abnormal or power is cut off, it switches to inverter power supply in milliseco-

nds, and the equipment will not stop and disconnect the network in the whole process, which fully adapts to the unattended base station 

operation and maintenance requirements. In addition, the model with pure sine wave output must be selected, and the output waveform 

is consistent with the commercial power, which will not interfere with the operation of precision communication equipment and will not 

damage the components of the equipment, so it is more reliable for long-term use.

Environmental adaptability can't be ignored. Outdoor base stations have large temperature difference and heavy dust and moisture. Ord-

inary civil-grade inverters can't carry this environment, and components are prone to aging and heat dissipation failures. Industrial inverter 

generally adopts metal body, with intelligent temperature control and heat dissipation, which supports wide temperature environment 

operation, and also has a full set of protection mechanisms such as overvoltage, undervoltage, overload and short circuit. Even if the field 

power grid fluctuates greatly, it can run stably and reduce the frequency of on-site maintenance. Our 2KVA model also supports RS485 

communication interface, which can be connected to the centralized monitoring system of the base station, so that we can check the runn-

ing status and receive fault alarms in real time remotely, and we can master the equipment situation without running to the site.
