Telecom DC Generators
The telecom sector is one of the largest consumers of energy worldwide. Each BTS site requires continuous power without interruption to serve customers’ mobile telephony needs. This requires each site to have a backup power supply available in the form of a generator and battery bank. In addition to sites requiring backup power, many sites, especially in developing countries, lack a grid connection. Therefore, they rely entirely on distributed generation in the form of a generator and renewable energy.
To power up, BTS signals require DC power. Traditionally, backup power sites have used AC generators because of their availability in the market. These generators have not been engineered to maximise efficiency and instead try to have the lowest capital expenditure possible.
PMG’s DC Generators meet the telecom sector needs by the following measures:
The DC Generator uses a highly efficient permanent magnet alternator rated at over 93% efficient. This compares to a traditional alternator having less than 78% efficiency which dramatically reduces at decreased loads.
The DC Generator uses a Variable Smart DC Generator Controller. This changes the speed of the engine according to the load requirement of the site. The engine lowers the speed as the electric load decreases. Doing all of this while maintaining a constant charging voltage.
