SARBS articles tagged DC Power on batteries, rectifiers, towers and telecom power.
The SARBS 48V 100Ah LiFePO4 battery is built as a lighter, longer-lived drop-in beside lead-acid on a telecom DC bus.
The SARBS rectifier is a compact shelf of up to six modules that turns a wide, messy AC feed into 54V DC for the radio and the batteries.
A tower is on air only when the DC plant, the battery, the cabinet and the earth path are all finished. Here is the order SARBS sites actually follow.
Before the rectifier sees power, a board, a breaker and sometimes a generator have to present a safe feed. SARBS supplies that side of the site too.
