## Key Features
• Universal input acceptance (AC and DC) simplifies integration across global designs
• Remote sense on main output compensates for up to 0.5 V lead drop
• Built-in EMI filter minimizes conducted and radiated emissions
• Short-circuit and overload protection on all outputs (110–145% derating)
• Overvoltage clipping: 5.7–6.7 V DC on main output
• Reverse connection protection
• High peak ratings sustained for 30 seconds

## Typical Applications
Commercial IT equipment requiring multi-voltage power rails. Network infrastructure, server peripherals, telecommunications modules, and industrial control systems benefiting from a small footprint and wide input tolerance.
## Compatibility & Integration
Open-frame construction enables direct PCB mounting and thermal integration into larger assemblies. Main output adjustability and remote sense allow field optimization for cable drop compensation. Triple outputs accommodate mixed-voltage subsystems without auxiliary regulation.
