Driver for APC Back-UPS BR UPS equipment

Synopsis

microsol-apc -h

microsol-apc -a UPS_NAME [OPTIONS]

Note

This man page only documents the hardware-specific features of the microsol-apc driver​. For information about the core driver, see nutupsdrv(8)​.

Supported Hardware

This driver supports the following UPS models:

In 2009, Schneider Electric acquired Microsol Technologies, and by 2012, the entire Microsol line was being sold under the APC brand​. This driver supports these newer, APC-branded models​. Older equipment should use solis(8)​.

Extra Arguments

This driver support the following extra optional settings in the ups.conf(5)​.

battext=n

Default = 0, no extra battery, where n = Ampere*hour​.

prgshut=n

Default = 0, no programmable shutdown; 1 to enable one​.

Commands

shutdown​.return

Shut down in ​.3 minutes and restart in ​.3 minutes after that​.

shutdown​.stayoff

Shut down in ​.3 minutes and do not return​.

Issues

For other APC-Microsol models, the reported voltages, currents and power will be incorrect, as the communication protocol reports unprocessed data instead of real values, needing model-specific post-processing by the driver​. Monitoring of UPS state (on-battery/on-line, critical battery) should work for other models, but is untested​.
