Apcupsd, short for APC UPS daemon, is a utility that runs on Linux, UNIX, macOS and Windows. [1]: 1, 8–9 It allows the computer to interact with APC UPSes. Apcupsd also works with some OEM-branded products (e.g. Hewlett-Packard) manufactured by APC. [1]: 7 [2] [3] Apcupsd is a free software equivalent of the APC's proprietary PowerChute software.
The Smart-UPS is a series of enterprise-level uninterruptible power supplies (UPS) made by American Power Conversion (APC). [1] Most of the units have a SmartSlot (with the exception of SC and SMC series) which accepts an optional interface card providing features ranging from network connectivity to temperature and humidity monitoring.

Pavel KoĊenský's original apcd provided the inspiration for pursuing the APC Smart-UPS protocol in 1996. [4] This is the same software that Apcupsd derived from, according to the Debian maintainer of the latter. [5] Russell Kroll, the original NUT author and coordinator, released the initial package, named smartupstools, in 1998.
APC Smart-UPS is a line of smaller units intended for home and office use, available as floor-standing and rackmount versions. With the exception of the Smart-UPS Online series (SURT and SRT models), Smart-UPS units are line-interactive UPS systems, running their outputs off the inverters only when the grid power is unavailable.
In low-voltage conditions the UPS will use more current than normal, so it may need a higher current circuit than a normal device. For example, to power a 1000 W device at 120 V, the UPS will draw 8.33 A. If a brownout occurs and the voltage drops to 100 V, the UPS will draw 10 A to compensate.
APC-7 connector, a coaxial connector used for high frequency applications; Application Program Command, a C1 control code; Asynchronous procedure call, a function that executes asynchronously in the context of a specific thread on Microsoft Windows; Atari Punk Console, a simple DIY noisemaker circuit; VIA APC, a low-cost Android PC computer
This process included a lengthy alignment process in which the vision engineer would work with the camera operator, to adjust the settings on both the actual camera and the CCU in tandem. [1] During production, it was the vision engineers' job to operate the CCUs and control both the exposure and the colour balance .
Drawing showing the relative sizes of sensors used in most current digital cameras. Advanced Photo System type-C (APS-C) is an image sensor format approximately equivalent in size to the Advanced Photo System film negative in its C ("Classic") format, of 25.1×16.7 mm, an aspect ratio of 3:2 and Ø 30.15 mm field diameter.
