6EP3436-8SB00-0AY0 | SITOP PSU8600 24V DC 20A (480W) System Power Supply Module

Product Overview

Technical Specifications (Electrical & Output)

Technical Specifications (Mechanical & Environmental)

Key Features

• PSU8600 Modular Expandability:​ Accepts clip-on modules — Buffer Module (6EP4398-8RB01 — 4s to 20 min hold-up), Redundancy Module (6EP4398-8RB00 — diode OR-ing for N+1), and Communication Module (6EP4398-8SB00 — PROFINET / PROFIBUS diagnostics).
• High Inrush Capability:​ 150% boost current handles capacitive loads (long 24V DC cable runs, large contactor coils) at power-up without nuisance trip.
• Adjustable Output:​ 22.2–28 V DC trim compensates for voltage drop on long DC distribution runs (compensation up to ~2 V @ 20 A).
• Diagnostics Ready:​ With comms module, reports output voltage/current, temperature, and status to PLC/SCADA — enables predictive maintenance of the 24V DC bus.

Applications

• S7-400 / PCS 7 Control Cabinets:​ Primary 24V DC supply for CPUs, signal modules, ET 200 distributed I/O, and HMIs in process plants.
• Large Machine Centers:​ Powering S7-300/1500 + distributed I/O + safety modules in a single-rack solution with buffered shutdown.
• Building / Infrastructure Automation:​ Feeding DDC panels, fire dampers, access control with buffered hold-up via PSU8600 buffer module.
• Redundant Power Architectures:​ N+1 redundant 24V DC bus when paired with the PSU8600 redundancy (OR-ing) module and a second basic unit.
