Terminology and Abbreviations

? DC UPS¡ªUninterruptible power supply with DC input.

? Normal mode¡ªDescribes a condition where the battery is charged, the input voltage is in range and the output is loaded within the

allowed limits..

? Buffer mode¡ªDescribes a condition where the input voltage is below the transfer threshold level, the unit is running on battery (buffering)

and the output is loaded within the allowed limits.

? Charging mode¡ªDescribes a condition where the battery is being charged, the input voltage is in range and the output is loaded within the

allowed limits.

? Inhibit mode¡ªDescribes a condition where buffering is disabled intentionally by using the inhibit input of the DC UPS (e.g. for service

actions or to save battery capacity).

? Buffer time¡ªEquivalent to the term ¡°hold-up time.¡±

? T.b.d.¡ªTo be defined, value or description will follow later.

1. Description

2. Specification Quick Reference

The 1606-XLS240-UPSD uninterruptible power

supply (UPS) controller along with a standard 24V

power supply and one 12V battery can bridge power

failures or voltage fluctuations. This unit can supply

and bridge both a 24V load as well as a 12V load at

the same time. The 12V is generated by a DC/DC

converter from the 24V output. Therefore, systems that

use 24V control circuits and require 12V for e.g.

remote radio telemetry can be supplied with

only one 1606-XLS240-UPSD DC-UPS controller.

Input voltage

The DC-UPS includes a professional battery

management system which charges and monitors

the battery to achieve the longest battery service life

as well as many diagnostic functions that ensure a

reliable operation of the entire system.
