## Long description

The MEAN WELL SDR-480P-48 is a metallic DIN-rail power supply unit delivering 480 W continuous output with peak capability up to 720 W (150% peak load). It accepts an AC input voltage range of 90–264 V, features built-in active power factor correction (PF \> 0.94), and offers high conversion efficiency (around 94%) with low power dissipation. The unit includes a DC OK relay contact, constant current limiting, and multiple protections for industrial use. It is compact and designed for TS-35/7.5 or 15 DIN-rail mounting and carries UL508 and TUV EN60950-1 related approvals.
Advantages
The SDR-480P-48 provides high efficiency and low heat generation, enabling reliable operation in confined electrical cabinets. Its 150% peak load capability and built-in active PFC improve compatibility with varying loads and help stabilize mains current. A full set of protections (short circuit, overload, over voltage, and over temperature) plus a DC OK relay contact support safe integration into industrial control systems. The unit is factory burn-in tested at full load to ensure long-term reliability and a rated MTBF of 112,900 hours.
Suitable for
Industrial control cabinets and automation systems
DIN-rail mounted PLCs, relays and I/O modules
Applications requiring stable 48 V DC power with high reliability

How to use
Install the unit on a TS-35/7.5 or 15 DIN rail inside an electrical cabinet with adequate clearance for convection cooling. Connect the AC input (90–264 V) and verify correct wiring and earthing according to local regulations. Connect the 48 V DC output to the load, and monitor the DC OK relay contact if system supervision is required. Ensure load currents remain within rated continuous and peak limits; the built-in current limiting and protections will act in fault conditions.
Usage recommendations
Allow sufficient ventilation around the power supply to maintain ambient temperature within the specified operating range, avoid mounting directly above heat sources, and perform periodic inspections of connections. Use the DC OK relay contact for external monitoring and integrate the unit within systems compliant with industrial EMC and safety standards.
