Description
The compact and flexible all-in-one solution REX consists of several
perfectly matched components. It comprises the EM12-T supply
module for the plus and minus potential via a single or double channel
REX12-T electronic circuit protector which can be mounted side by
side in any number and the PM12-T potential extension module for
plus and minus multiplication. Connection of the only 12.5 mm wide
modules is exclusively with push-in terminals which allow no-tool
time-saving wiring.
The circuit protectors are placed on the symmetrical rail one after
another in combination with EM12-T and PM12-T and are electrically
connected by means of the built-in connector arm - no further acces-
sories are required. The circuit protector REX12-T offers selective over-
current protection by responding to short circuit or overload faster than
the switch mode power supply. Capacitive loads of up to 20,000µF
can be switched on without problems. The circuit protector is available
in all standard fixed and adjustable current ratings from 1 A to 10 A.
Besides the UL508listed approval and NEC Class2, the REX12-T also
meets the requirements of cable protection to EN60204-1.
