First 48V redundant DC-DC converter for telecom and datacentre
The Artesyn CSU2000ADC-3 is the industry’s only carrier-grade 48V DC-DC converter in the CRPS redundant power supply form factor 

Advanced Energy (AEIS) has launched a 2kW DC-DC converter for high reliability designs in telecoms and data centre applications to 48V architectures.

The Artesyn CSU2000ADC-3 -48V to 12V DC-DC converter is the first to use the CRPS common redundant power supply form factor that measures 73.5 x 185 mm, says the company.

The CSU2000ADC-3 has -70V to -48V input and 12V output at 2000 W with the CRPS form factor making it simple for customers to design into systems. It is aimed applications in traditional AC data centres, DC telco central offices, as well as increasingly-common DC data centres.

“Our customers want a one-stop partner for power conversion solutions and this introduction of a 48-volt DC-input power supply is the next important milestone in building our complete CSU series portfolio,” said Brian Korn, vice president and general manager of data centre computing, telecom and network products, Advanced Energy. “Our new CSU2000ADC-3 provides our customers with the predictable performance and future-proof system designs they’ve come to expect from AE.”

AE points to exponential growth in data computing, storage and networking, fueled by accelerated adoption of cloud computing and Internet usage, as well as growing investments in hyperscale data centre infrastructure. To meet the growing demand, today’s data centres require increased compute density and that in turn requires a higher level of power density.

The 1U high CSU2000ADC-3 has a power density of 62 W/in 3 and is based around silicon MOSFETs with a peak efficiency of 94 percent. It uses two-hole terminal lugs to handle high input current and includes inrush current control, N+M redundancy and hot plug support. There is active current sharing and full digital control via a PMbus.
