Siemens 6EP4136-3AB00-0AY0 SITOP UPS1600 24V DC 20A Uninterruptible Supply

The Siemens 6EP4136-3AB00-0AY0 is a SITOP UPS1600 DC uninterruptible power supply module rated 24 V DC at 20 A, providing 21-29 V input buffering with an adjustable cut-in threshold and a rotary-switch-selectable backup time from 0.5 to 20 minutes. It delivers up to 60 A peak, runs at 97.7% efficiency with 10 W typical power loss, and carries an IP20 rating in a compact 50 x 139 x 125 mm DIN-rail enclosure weighing 0.39 kg.

Selection Notes

The rotary-coded backup-time switch (0.5 to 20 minutes, or maximum) sets how long the 24 V rail rides through a supply interruption before the connected battery module is exhausted, letting the same UPS1600 serve either a quick-ride-through role or a full shutdown-sequence role without reprogramming. The adjustable cut-in threshold (21-25 V in seven steps) lets it buffer only on a genuine dip rather than normal ripple from a lightly loaded 24 V supply. At 20 A rated and 60 A peak, it covers inrush from contactors and solenoids during the switchover without derating the connected battery module.

Applications

Used to bridge short mains interruptions for PLCs, I/O, and drives on a 24 V DC bus in control cabinets where an orderly shutdown or ride-through is required instead of an immediate loss of power.
