The 6EP4347-7RB00-0AX0 is a SITOP PSU8600 buffer module from Siemens, designed to provide buffered power supply for 24V DC industrial systems with UPS functionality. Here's a detailed breakdown:
Manufacturer: Siemens
Product Line: SITOP PSU8600 (modular power supply system)
Type: Buffer module (with supercapacitor backup)
Input Voltage: 24V DC (from main PSU8600 power supply)
Output Voltage: 24V DC (buffered)
Backup Time: Up to 30 seconds (typical, depending on load)
Supercapacitor-Based: Maintenance-free, long lifespan (vs. batteries)
Mounting: Snap-on to PSU8600 base unit
? Short-term power buffering during grid fluctuations
? Safe shutdown of PLCs/controls during power failures
? Prevents data loss in automation systems
? Ideal for:
SIMATIC S7-1500/ET 200SP systems
Critical sensors/actuators
Industrial PCs/HMIs
Feature | 6EP4347-7RB00-0AX0 (Buffer) | 6EP4136-3AB00-0AY0 (Battery Backup) |
