Siemens Logo! Stabilized power supply, 5VDC, 3A Part number 6EP3310-6SB00-0AY0

Product Overview

The Siemens 6EP3310-6SB00-0AY0 is a DIN-rail mounted switching power supply from the LOGO!POWER series. It converts single-phase AC (or DC) input into a stabilized 5 V DC output at 3 A, providing a compact and reliable supply source for logic modules, controllers, and small automation devices — ideal where low-voltage DC power is required.

Key Features

• Switched-mode DIN-rail power supply (LOGO!POWER series)
• Input: 100–240 V AC (single-phase) or 110–300 V DC (wide-range); supports wide voltage tolerance
• Output: 5 V DC, 3 A (fixed, regulated)
• Isolated, stabilized DC output with galvanic separation between input and output — safe low-voltage output
• Compact DIN-rail housing — easy to install in control panels or enclosures
• Short-circuit, overload, and overvoltage protection built in, ensuring safe operation under fault conditions
• Internal fuse protection; recommended external protection via miniature circuit breaker
• Rapid output voltage recovery and mains-buffering capability for short interruptions (minimum 40 ms buffering at rated load) — improves resilience against supply disturbances
• Status LED indicating “5 V OK” output — easy operational monitoring
• Post-fail safe operation: no output overshoot or harmful transients at startup (soft-start behavior)

Compliance & Standards

• Galvanic isolation ensures SELV-class output, compliant with safety requirements for low-voltage outputs
• Conforms with relevant standards for industrial switching power supplies — including short-circuit and overvoltage protection norms
• Designed for industrial use in control cabinets, automation enclosures, and electrical distribution systems

Applications

The 6EP3310-6SB00-0AY0 is ideal for supplying 5 V DC power to logic and control modules, small controllers, PLC I/O expansion modules, sensor/actuator interfaces, and other low-voltage devices in automation panels, machine control cabinets, or compact control enclosures. Well suited for small automation tasks, building automation, compact control cabinets, and equipment that requires a stable, regulated 5 V DC supply.
