1-phase and 3-phase power supply SITOP modular

• Stabilized; with wide-range input for connection to 1-phase or 3-phase networks worldwide
• Output currents 24 V DC with 5 to 40 A
• Efficiency up to 93%; 50% extra power for up to 5 s
• Settings for operational overload:
  • Constant current with automatic restart
  • Latching shutdown
• "Soft characteristic curve" for optimal load distribution with parallel connection
• Power boost for short-term 3x rated current for tripping protective devices
• Signaling of operating status via 3 LEDs and signaling contact

Add-on modules

Signaling module

• Provision of alarm signals for the operating status of the power supply
• Can be combined with SITOP modular power supply, 6EP1x3x3-3BA00

Redundancy module

• Decoupling of two power supplies in parallel operation via diodes
• 24 DC power supply is maintained in the event of power failure
• Message display via LED and floating relay contact

Back-up module

• Buffering the load current during brief power interruptions
• Wiring parallel to the output of the power supply
• Buffer time of 200 ms with 40 A, up to 1.6 s with 5 A load current

Selectivity module

• Distribution of the load current over up to 4 current circuits
• Monitoring of individual partial currents
• Selective cutoff of all circuit currents at overload or short-circuit
• Signaling via LEDs (channel-by-channel) and, depending on the version, common signaling contact or single-channel message
• Selectivity modules with single-channel message output the status of the 4 current circuits by means of a code that can be read by a digital controller input and evaluated with function blocks.
