Help and assumptions

Enter AC input watts, including supply losses and downstream loads. For a DC controller or lock, include its load once at the AC power supply input. Do not add it again as an independent AC circuit. For PoE switches, include the intended PoE load and power-supply losses in input watts. Device Details lets you enter heat released inside this room separately from remote power delivery.

Library values are editable planning allowances, not universal maximum ratings. Verify selected models, configuration, and supply paths. UPS input/output voltages are separate; conversion must be specified. Runtime requires model-specific load points. Electrical and mechanical complete final sizing.

PER-RACK BREAKDOWN
POWER CONSUMPTION & CIRCUIT SCHEDULE
  • Power Factor. Default 0.90 applied to all loads. Adjust under Global Settings for known equipment behavior.
  • 125% Planning Allowance. Applied once to preliminary circuit current and ICT generator load. This does not establish a code requirement or final equipment selection.
  • Wall-Mount Device Wattages. Wall rows represent complete AC supply or system inputs. Include downstream controllers, readers, locks, losses, and charging once at the supply. Do not create independent AC rows for DC components. Verify the installed configuration.
  • Cooling Load. Room heat watts, adjusted by the recorded load factor, × 3.41214 = BTU/hr. Blank room heat assumes all input stays in this room. Cooling allowance includes a 25% buffer and the configured ambient percentage.
  • Generator Sizing. Total load × 1.25 (continuous). Growth recommendations show +25% and +50% above continuous.
  • UPS Runtime. Individual connections and recorded manufacturer load points determine the result. No batteries are pooled, and no runtime is interpolated. Missing load points remain unknown. A/B checks each source at full transferred load; parallel systems require vendor modeling.
  • Breaker Selection. Breaker shown is the next standard commercial size at or above calculated continuous-load current. Final breaker and conductor sizing by licensed electrical engineer.
  • Redundant Power Supplies. Enter complete device input once. Confirm efficiency, loading, and failure behavior. A redundancy objective does not establish availability or N+1 compliance.
  • Scope. Preliminary planning and coordination only. PLEX does not replace stamped electrical design. All outputs require review and sign-off by a licensed electrical engineer.
