Siemens 6EP4293-8HB00-0XY0 SITOP BUF8600 4s/40A PSU8600 Power Supply Buffer Module
SITOP BUF8600 buffer module for PSU8600, 4s ride-through at 40A, double-layer caps
Description
About the BUF8600
About the BUF8600
The Siemens 6EP4293-8HB00-0XY0 is a SITOP BUF8600 buffer module that plugs directly into a SITOP PSU8600 power supply and uses maintenance-free double-layer capacitors to hold a 40 A load for 4 seconds during a mains interruption. It recharges in about 5 minutes at 400 V, reports buffer status over Ethernet/PROFINET through the PSU8600, and needs no external battery or separate field wiring to operate.

Selection Notes
Rated for a 4-second bridge at the full 40 A load, this module recharges to full readiness in about 5 minutes at 400 V between events, which sets how often it can absorb repeated short interruptions without losing backup capability. Because it draws power through the PSU8600's integrated connector rather than separate input terminals, it adds this buffer duration to a PSU8600 rack without extra field wiring beyond the control and status contacts. Pick this duration for momentary sags and switching transients rather than a sustained outage that needs a longer ride-through.
