IEEE Open Journal of Industry Applications (Institute of Electrical and Electronics Engineers (IEEE)) 2020
Keep bus gap as an input in arc flash calculations for DC panels and battery busbars; do not rely on the maximum-power method alone.
Schneider Electric 2011
Store UPS efficiency as a curve with at least 25/50/75/100% load points, plus storage type (battery, flywheel) and ride-through seconds.
Vertiv 2024
Record telemetry capability (protocols, factory sensors, remote monitoring support) in the equipment catalog.
Schneider Electric 2017
Distinguish 'N+1 internal modular', 'N+1 parallel redundant' and 'isolated redundant' instead of a single N+1 flag; for modular frames store module rating, max modules, shared battery bus and redundant controls/fans.
Eaton 2025
Add grid-code parameters to the utility connection object: UFLS stages, LVRT curve, post-fault power recovery ramp (%/s) and short-circuit ratio at the PCC.
Consulting-Specifying Engineer 2018
In business-model templates (enterprise, colo, cloud), set default redundancy and base-to-redundant ratios.
Lawrence Berkeley National Laboratory, Center of Expertise for Energy Efficiency in Data Centers 2023
Benchmark the electrical loss model against this tool's structure: transformer, UPS and PDU efficiency curves by load factor, plus eco-mode.
Open Compute Project Foundation 2026
Choose the voltage class with LV limited to 1500 VDC; check that sources stay below it in steady state (for example 750 V per pole) and that device voltage windows fit; 800 V devices with only a +/-5% range cannot operate below 750 V and are unusable there.
arXiv preprint (University College Dublin) 2025
Expose UPS transfer thresholds (voltage %, frequency Hz), return-to-mains delay and staggering across UPS modules as design parameters, and warn when all modules share identical thresholds and delays, since synchronised reconnection can re-trip the grid.
Consulting-Specifying Engineer 2013
Offer distribution-voltage options (208/120, 415/240, 380 Vdc) with automatic loss and fault-current comparison.
Huawei Digital Power 2022
Add a 'prefabricated power train' block type (transformer, LV, UPS, feeders) carrying footprint, weight and a clearance envelope.
Eaton 2013
Allow UPS placement in the white space with an airflow-pattern attribute (front-to-back, front-to-top) and count its heat release in the hall cooling load.
Legrand 2022
Give UPS records an architecture enum {conventional, modular, scalable_modular}, module rating, maximum parallel units, MTTR hours and a hot-swap flag; store efficiency at 25/50/75/100% load, not one number.
ABB 2022
Use it as a template for a '2N LV, 0.5 MW' starter project, auto-generating the RPDU, RPP, secondary board, UPS, main board and transformer/generator chain from rack count and kW/rack.
Uptime Institute Journal 2019
Support generator-less or reduced-generator options in the design wizard (fuel cell, long-duration BESS) with explicit autonomy-hours calculation and load-shed tiers.
Socomec 2024
In the single-line editor, tag transfer devices as ATSE (IEC 60947-6-1) or STS with a transfer-time field, and suggest STS where the load needs under about 10 ms.
IEEE Open Journal of Industry Applications (Institute of Electrical and Electronics Engineers (IEEE)) 2024
For UPS battery arc-flash checks at 380-1000 VDC, expect incident energy to rise sharply with voltage and arc duration above roughly 500-800 V.
Springer Science and Business Media LLC (preprint) 2026
Make the 0.1-10 Hz oscillation, 1.40 peak-to-mean ratio and coincidence factor explicit inputs in the AI campus load model, and check storage and buffering against grid ramp limits.
Electronics (MDPI AG) 2018
When selecting double-conversion UPS, include the measured efficiency curve by load point and the annual energy cost of the loss difference (here about 1380 USD per year for 450 W) in total cost of ownership.
Consulting-Specifying Engineer 2018
Support both distributed-redundant and catcher/reserve UPS topologies with automatic post-failure load checks, warning if any unit exceeds 100% after a single failure.
Schneider Electric 2016
Store full UPS efficiency curves (10/25/50/75/100% load), ride-through, footprint and service clearance, and a technology field (static VRLA, static Li-ion, DRUPS) rather than one peak value.
Eaton 2017
Treat the UPS in inverter mode as a current-limited source in the short-circuit engine, with catalogue fields inverterIscMultiple, inverterIscDuration_ms, bypassIcw and maxProspectiveFaultAtBypass.
Buildings (MDPI AG) 2025
Plan UPS maintenance from a condition table that maps each unit's state to MTBF and MTTR, then pick the units to maintain that meet target availability at the lowest cost.
arXiv preprint (Stanford University) 2026
Offer rack-level smoothing storage (filter + battery/supercap + DC regulator) as a catalog item for HVDC AI racks, sized by peak power swing and grid ramp limit rather than backup energy.
