NAME

       al175 - Driver for Eltek UPS models with AL175 alarm module

NOTE

       This man page only documents the hardware-specific features of the al175 driver. For
       information about the core driver, see nutupsdrv(8).

SUPPORTED HARDWARE

       The al175 driver is known to work with the following UPSes:

           Eltek MPSU4000 with AL175 alarm module

       It may also work with other UPSes equipped with AL175 alarm module, but they have not been
       tested.

       AL175 have to be configured to operate in COMLI mode. See documentation supplied with your
       hardware on how to do it.

EXTRA ARGUMENTS

       This driver does not support any extra settings in the ups.conf(5).

INSTANT COMMANDS

       This driver supports some extra commands (see upscmd(8)):

       test.battery.start
           Start a battery test.

       test.battery.stop
           Stop a battery test.

VARIABLES

       Besides status, this driver reads UPS state into following variables:

       •   ups.test.result

       •   output.voltage.nominal

       •   output.current

       •   battery.voltage.nominal

       •   battery.current

       •   battery.temperature

       •   input.transfer.boost.low

KNOWN ISSUES AND BUGS

       •   Shutdown is not supported. FIXME

       •   The driver was reworked to meet the project code quality criteria, without testing on
           real hardware. Some bugs may have crept in.
