4U power supply AC2000 N1 AC3000 N1 DC2000 N1 DC3000 N1

AC/DCswitchingfor industrial applications

Description
The AC2000 N1 and AC3000 N1 SMPS rectifiers and the DC2000 N1 and DC3000 N1 DC converters are 19" 4HU natural-cooled modules designed for continuous, secure DC power delivery in industrial and nuclear environments. Available output power is 2.1 kW (65 A) or 3.2 kW (100 A) depending on model. The units are fully analog controlled to avoid programmable software components and reduce the need for software certification, thereby lowering the attack surface for cybersecurity.

Highlights

• Industrial-grade design for harsh environments and critical installations
• Fully analog control: no freely programmable digital interfaces
• SiC power stage for high efficiency (~94%) and reduced operating losses
