Testing UPS Output Waveforms
이 글은 사무실에 있는 여러 UPS(무정전 전원 공급 장치)를 오실로스코프와 프로그래머블 AC 전원 공급 장치를 이용해 출력 파형을 측정하고 분석한 탐구성 테스트 결과를 다룹니다. Eaton SMART1500PSRTNC는 순수 사인파 출력을 제공하는 반면, 저가형 APC BE750G는 모의 사인파를 출력해 민감한 장비에 영향을 줄 수 있음을 확인했습니다. APC BN1500M2-CA 모델은 일부 장비가 배터리 모드에서 비정상적인 파형을 보여 고장 가능성을 시사합니다. 테스트는 고전압 안전 문제를 고려해 절연된 AC 소스를 활용해 진행되었으며, UPS 전환 시 파형 변화와 지연 현상도 관찰했습니다.

If your power went out right now for 72 hours, what's the first thing that would cause a problem?
For most: the fridge. For some: a CPAP or medication needing refrigeration.

Today's Ready Brief: Home Power Backup — Your Options Ranked
Portable power stations vs. generators vs. batteries. Carbon monoxide risks. Solar charging reality check.

Home power backup, ranked by value:
1. Portable power station ($200-500) — quiet, safe indoors
2. Gas generator ($400-800) — more power, CO risk, outdoor only
3. Whole-home battery ($5k+) — best if budget allows
The thing that kills during outages? Carbon monoxide from indoor generators. Every storm season.
