MAXLINEV is the maximum line voltage since the last STATUS as returned by the UPS.

MINLINEV is the minimum line voltage since the last STATUS as re- turned by the UPS.

OUTPUTV is the voltage the UPS is supplying to your equipment.

SENSE is the sensitivity level of the UPS to line voltage fluctuations.

DWAKE is the amount of time the UPS will wait after a power off con- dition when the power is restored.

DSHUTD is the grace delay that the UPS gives after receiving a power down command from apcupsd before it powers off your equipment.

DLOWBATT is the remaining runtime below which the UPS sends the low battery signal. At this point apcupsd will force an immediate emergency shutdown.

LOTRANS is the line voltage below which the UPS will switch to bat- teries.

HITRANS is the line voltage above which the UPS will switch to batter- ies.

RETPCT is the percentage charge that the batteries must have after a power off condition before the UPS will restore power to your equip- ment.

STATFLAG is a status flag indicating the UPS status. See STATUS.

ITEMP is the internal UPS temperature as supplied by the UPS.

ALARMDEL is the delay period for the UPS alarm.

BATTV is the battery voltage as supplied by the UPS.

LINEFREQ is the line frequency in Hertz as given by the UPS.

LASTXFER is the reason for the last transfer to batteries.

NUMXFERS the number of transfers to batteries since apcupsd startup.

XONBATT time and date of last transfer to batteries, or N/A.

TONBATT time in seconds currently on batteries, or 0.

CUMONBATT total (cumulative) time on batteries in seconds since apcupsd startup.

APC UPS control system manual

UPS control system specifications

APC UPS (Uninterruptible Power Supply) control systems are vital components for ensuring uninterrupted power supply and protecting critical equipment from power interruptions, surges, or fluctuations. Designed by Schneider Electric, APC UPS systems are renowned for their high quality and reliability. They utilize advanced technologies and features to suit diverse applications, from home offices to large industrial settings.

One of the main features of APC UPS systems is the ability to provide backup power during outages. This is achieved through a battery system that activates immediately when the mains power fails. This seamless transition minimizes downtime and ensures that electronic devices continue to operate, protecting data integrity and equipment lifespan.

Another significant characteristic of APC UPS systems is their intelligent management capabilities. Most models come with PowerChute software, which provides users with real-time monitoring of power conditions and the status of the UPS. This software allows for graceful shutdowns of connected devices during extended outages, thereby preventing data loss and damage to devices.

APC UPS systems also incorporate advanced technologies such as Automatic Voltage Regulation (AVR). AVR technology ensures that the output voltage remains stable by correcting minor fluctuations without switching to battery mode. This not only prolongs the battery life but also provides a consistent power supply to the connected equipment.

Thermal management is another critical aspect of APC UPS control systems. The design often includes efficient cooling systems that prevent overheating, ensuring optimal performance and longevity of the unit. Some models feature EcoMode, which reduces energy consumption and lowers operational costs by working at high efficiency only when battery backup is not required.

APC UPS systems are designed with scalability in mind. Users can easily add more batteries or connect additional UPS units to accommodate growing power needs. Features such as hot-swappable batteries and modular design facilitate easy upgrades and servicing without interrupting power supply.

In terms of connectivity, APC UPS products often feature multiple options including USB, RS-232, and network management capabilities. This enables users to connect remote management tools and integrate the UPS with existing IT infrastructure.

In summary, APC UPS control systems deliver reliability, efficiency, and advanced technology features that cater to a wide array of power protection needs, making them a trusted choice for individuals and businesses alike.
