Outdoor Cabinets That Protect Equipment on the Tower

Plenty of towers have a concrete pad and a fence, and nowhere dry to put a rectifier. The outdoor cabinet is how SARBS houses that equipment. The company describes it as a cabinet that holds the gear, keeps it working on its own, and protects it from the weather in every season.

What goes inside

SARBS says these cabinets supply uninterrupted power to wireless communication, digital cable and wireless network equipment. The equipment installed inside is expected to follow ETSI 19, the standard rack footprint radio and transmission people already design to. That is the practical constraint: if the radio, the rectifier and the battery plan are ETSI 19, the cabinet does not become a custom metal box.

Heat, rain and dust are the real enemies. A cabinet that only sheds rain but cooks the rectifier will show up later as dried capacitors and a short battery life. Ask about the thermal path at the same time as the footprint. The battery, whether gel or LiFePO4, needs the same conversation.

Cabinet, rack and power as one visit

The cleanest installs put the rectifier, the battery string and, where theft is a risk, the anti-theft rack into the cabinet layout before the concrete is poured. SARBS lists the outdoor cabinet for telecom on its product page. Civil and rollout teams can line the pad up with the cabinet drawing during site rollout.
