The -48V back-up battery converter is similar in construction and complexity to the single-output, high-power VoIP converter previously discussed. The power factor corrected (PFC) AC/DC produces the supply voltage for the 3G Base station''s RF Power amplifier (typ. +27V) and the bus voltage for point-of-load converters.
Telecom and wireless networks typically operate on –48 V DC power, but why? The short story is that –48 V DC, also known as a positive-ground system, was selected because it provides enough power to support a telecom signal but is safer for the human body while doing telecom activities.
Compatibility and Installation Voltage Compatibility: 48V is the standard voltage for telecom base stations, so the battery pack’s output voltage must align with base station equipment requirements. Modular Design: A modular structure simplifies installation, maintenance, and scalability.
In a DSL application, a -48V to multiple output converter may be used which incorporates a more complex, lower power transformer (50-100W) with several outputs.
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
