How does a telecommunications system work?Since most telecommunications equipment at the site requires a DC voltage supply, the AC power from either the electric grid or the diesel generator is converted to –48 V DC by the rectifiers. These redundant rectifiers are used to convert the AC power to –48 V DC power used to trickle charge the batteries as well as support the critical loads.
What is a Telecom DC power system?The telecom DC power system typically includes the national electricity grid system, a diesel generator, a self-acting AC automatic transfer switch (ATS), a power distribution system, solar panels or boards, controllers and chargers, rectifiers, backup batteries arranged in series, and the corresponding cables and breakers. Figure 1.
What is a multi-output power supply design?Multiple output designs may also employ a complex regulation scheme which senses multiple outputs to control the feedback loop. Voice-over-Internet-Protocol (VoIP), Digital Subscriber Line (DSL), and Third-generation (3G) base stations all necessitate varying degrees of complexity in power supply design.
What is a 3G base station converter?In a 3G Base Station application, two converters are used to provide the +27V distribution bus voltage during normal conditions and power outages.
How much power does a PSU need?This is when the PSU is no longer powering the PA, which is the main power draw, but still needs to power other electronics. The current target for low-load efficiency is about 30 W. Some OEMs would like to see that drop to nearly 10 W.
What voltage does a DSL power system supply?The DSL power system may supply both higher voltage analog line drivers and amplifiers (typ. +/-12V) and several low voltage supplies required by the digital ASIC (+5V, +3.3V, +1.8V, +1.5
