Why High-Power UPS Systems Need Fans？

                                            Why High-Power UPS Systems Need Fans？
UPS systems (Uninterruptible Power Supplies) generate significant heat during operation, especially when:
Converting Power: AC to DC (charging) & DC back to AC (powering devices).
Delivering High Load: Supporting many devices draws more current.
Running on Battery: Battery discharge itself creates heat.
This heat can damage sensitive internal components (like transformers, capacitors & batteries) and reduce efficiency & lifespan.
Fans are essential for active cooling!  They pull cool air in & push hot air out, maintaining safe operating temperatures.  This ensures your UPS performs reliably during outages and protects your connected equipment.
