The Siemens 6EP3336-7SB00-3AX0 is the highest-performance single-phase SITOP PSU6200, delivering 24 V DC at 20 A with a class-leading 95.5% efficiency that minimizes heat dissipation and energy cost in continuously operated control panels. Diagnostic LEDs, a signaling contact, and 150% extra-power capability make it the go-to choice for mission-critical S7-1500 PLC racks and large automation systems.

Flagship Features

• 95.5% efficiency — only 22.5 W power loss at 480 W output, reducing cabinet cooling requirements
• Diagnostic interface with LED indicators and signaling relay for remote status monitoring
• 150% extra-power (30 A) for 5 seconds per minute handles large contactor and DC motor inrush
• 70 mm slim width at 1.5 kg — higher power density than both PSU100S (115 mm) and PSU100L (110 mm)

Technical Specifications

Positioning Among 480W Options

Siemens offers four 480 W / 20 A single-phase power supplies: PSU100L (discontinued), PSU100S (standard, 90%), PSU4200 (93%, push-in), and this PSU6200 (95.5%, diagnostics, extra-power). The PSU6200 is the premium choice where uptime, energy efficiency, and diagnostic visibility justify the incremental investment over the PSU4200.
