6EP3436-8SB00-0AY0 | SITOP PSU8600 24V DC 20A (480W) System Power Supply Module
6EP3436-8SB00-0AY0 SITOP PSU8600 basic module. 24V DC 20A output (480W), 3-phase 400–500V AC input, width 70mm, for S7-400/ET200SP/PCS7 cabinets with buffer & communication expansion.
Product Overview
6EP3436-8SB00-0AY0 is the basic power module of the SITOP PSU8600 modular system — a high-performance 24 V DC / 20 A (480 W) switched-mode power supply designed for demanding industrial automation backplanes. It accepts a 3-phase 400–500 V AC input and delivers a tightly regulated 24 V DC output with < 30 mVpp ripple. The PSU8600 architecture allows stacking of buffer (UPS), redundancy (OR-ing), and communication (PROFINET/PROFIBUS) modules directly onto the basic unit — making it the preferred 24V DC source for S7-400, PCS 7, and large ET 200SP/ET 200M cabinets requiring diagnostics and controlled shutdown.

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.
Note: This is the basic module only — buffer/redundancy/comms modules and the SITOP SELECT diagnostic module (6EP4398-8SB00 variant) are ordered separately. For single-phase input (100–240V AC) 20A version, see 6EP3336-8SB00-0AY0 (SITOP PSU300S series — not PSU8600 modular). The PSU8600 basic module requires a 3-phase input — verify your panel has 400V 3PH before specifying.
