al175 - Driver for Eltek UPS models with AL175 alarm module

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

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.

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

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

test.battery.start

Start a battery test.

test.battery.stop

Stop a battery test.

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

•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.
