Problem
UPS runtime is too short to safely transition the production system during a brief outage.
Solution
Root Cause / Diagnostic:
When primary mains power drops, an undersized battery topology or degraded lead-acid cell bank cannot sustain the combined VA load of the broadcast rig. The rapid voltage sag under heavy CPU/GPU encoding draw triggers premature low-voltage cut-offs before generator transfer or orderly software shutdowns complete. This leads to abrupt system termination, corrupting local multi-track recordings and terminating ingest connections.
Actionable Fix:
1. Size an online double-conversion (zero transfer time) UPS rated for at least 150% of the total measured wattage (e.g., 1500VA/1350W for an 800W draw) to guarantee a minimum 15-minute runtime at full broadcast load.
2. Separate non-critical production gear from critical path hardware by plugging auxiliary monitors and ambient lighting into a surge-only bank while keeping the main encoder, audio DSP, and network switch on battery banks.
3. Perform a cold pull-the-plug dry run during off-air testing while running OBS/vMix and stress encoding to verify real-world battery discharge time against software shutdown scripts.
Pro Tip:
Deploy network management cards (SNMP) on your UPS to automate network-wide graceful degradation alerts and trigger automatic scene changes to an emergency static slate before system power cuts.
