A workhorse 3-phase 24V DC power supply for medium-to-large automation panels, the SITOP PSU4200 6EP3436-3SB00-0AX0 provides 20A of stabilized power with the rugged protection suite required for round-the-clock industrial duty.

Solid 3-Phase Power for Automation

With 480W output, this unit comfortably powers a full-sized PLC system with remote I/O racks, multiple operator panels, and connected field devices. The 3-phase input draws balanced current across all three phases, simplifying panel power distribution design.

Protection Without Complexity

Short-circuit protection with automatic recovery, overload protection, overvoltage clamping, and overtemperature shutdown are all built in. No external fusing or protection modules needed for the power supply itself — the unit handles common fault conditions autonomously.

Deploy Anywhere

CE, UL, cUL, ATEX, and IECEx certifications support deployment across global manufacturing sites. The 320–500V AC input range accommodates voltage variations in facilities with unstable mains or long cable runs from the distribution transformer.
