DC-UPS-System

Industrial Power Supplies

TIS Series

50–600 Watt

In addition to the standard power supply function, these models

include a professional battery management system to charge and

monitor an external battery. In the event of a power failure the

battery is switched automatically and without any interruption to

the DC output. Once mains power is available again, the battery

is switched off. The backup time is limited only by battery capacity

and load. Charge current and voltage can be adjusted to values as

required by battery type. Power fail and low battery alarm signals

are available via two independent relay contacts. During normal

operation the battery status is monitored by periodically loading

the battery for a short time. If a cell resistance is high, there is a

relay alarm is available. The battery is fully protected under any

operational conditions. The power supply is short circuit protected

even in battery backup operation but, for safety reasons, the bat-

tery should be fitted with a fast blow fuse. Battery mode can be

activated by interconnecting pin 7 and 8.

Complete external battery packs (3.2 Ah or 7 Ah standard) with lead batteries and circuit breaker are available (see page 8).
