Siemens 6EP3436-7SB00-3AX0 SITOP PSU6200 24V/20A 3AC Diagnostics Power Supply

The Siemens 6EP3436-7SB00-3AX0 is a SITOP PSU6200 stabilized power supply that converts a 3-phase 400-500V AC input to 24V DC at up to 20A (24A to 45C), with a dedicated diagnostics interface and 95.9% efficiency. It supports parallel operation of up to 2 units for higher-capacity DC bus builds.

Selection Notes

The 3-phase 400-500V AC input distinguishes this unit from single-phase 120-240V models in the same PSU6200 family, so it fits machines already wired for a 3-phase feed rather than needing a single-phase tap. The diagnostics interface at the output adds a dedicated diagnostic signal beyond a basic DC-OK contact, useful for reporting power supply status back to the PLC. Parallel operation of up to 2 units, set with a DIP switch, extends total output to roughly 40A for larger DC buses without adding a redundancy module. The 24A rating applies only up to 45C ambient; the 20A continuous figure governs above that.

Applications

Central 24V DC power distribution for larger PLC/IO racks, motor control centers, and machine cells running on a 3-phase 400-500V supply, where load current or diagnostic feedback needs exceed what a single-phase, lower-current PSU6200 unit provides.
