Power That
Never Quits. For Hospitals. For Hospitals. For Data Centers. For High-Rise Buildings. For Government.

$44B

Annual cost of sustained US power interruptions

Lawrence Berkeley National Laboratory (2018) puts the economic cost of sustained outages at roughly $44 billion per year using peer-reviewed methodology.

54%

of data center outages cost over $100,000

Uptime Institute's 2024 analysis: half of significant outages now cross the six-figure threshold; one in five exceed $1M.

90 min

Egress illumination required after grid loss

NFPA 101 §7.9 mandates 1½ hours of emergency illumination along every egress path. Full brightness on minute 89 is the test.

10 s

Maximum activation time for emergency equipment

UL 924 requires emergency lighting and power equipment to reach full output within 10 seconds of normal-power loss. NFPA 110 Type 10 matches.

24 hr + 5 min

Standby + full-alarm duration required

NFPA 72 §10.6.7.2: secondary power carries 24 hours of standby plus 5 minutes of full alarm — 15 minutes with voice/MNS evacuation.

2 hr

Continuous evacuation power for safe egress

ASME A17.1 / IBC require a standby power source capable of operating the elevator and its accessories for safe evacuation during utility failure.

Type 1

Essential Electrical System for Category 1 care

NFPA 99 requires a Type 1 EES restoring power within 10 seconds for any space where power loss could cause patient death. UL 60601-1 leakage limits stack on top.

100 µA

Max chassis leakage for medical equipment

UL 60601-1 caps chassis leakage at 100 µA normal condition and 10 µA at the patient under single-fault condition — thresholds no standard UPS meets.

±5%

Utility service voltage tolerance (US)

ANSI C84.1 specifies ±5% utility service voltage tolerance. Sensitive equipment fails well inside that window — voltage regulation closes the gap.

5% THD

Voltage distortion limit at the PCC

IEEE 519 limits voltage THD at the point of common coupling to 5%. Isolation transformers and harmonic-mitigating PDUs keep non-linear loads inside the window.

400 Hz

Aircraft & defense electrical systems

MIL-STD-704 standardizes 400 Hz, 115 VAC three-phase power for US military aircraft. Ground-support gear requires frequency conversion from 60 Hz utility.

IEEE 1100

Grounding for sensitive electronic equipment

IEEE 1100 (Emerald Book) recommends isolation with electrostatic shielding for sensitive electronic loads — the spec behind medical imaging and broadcast clean-power requirements.
